A few years ago, Mike MacQueen, a historian working for the Department of 
Homeland Security, was at his desk combing through decades-old Bosnian military 
records, in search of war criminals who had eluded justice. The documents 
listed the names of top officers in a batallion implicated in the massacre of 
at least a thousand Muslim prisoners at a schoolhouse and dam in eastern 
Bosnia, in 1995. He noticed that the name of one Bosnian Serb officer kept 
showing up in the logs: Ilija Josipović.

MacQueen had turned himself into an unlikely expert on the war that unfolded in 
the Balkans two decades ago, mastering the Serbo-Croatian language, making two 
dozen trips to the region, and becoming so well schooled in the war crimes that 
Bosnian prosecutors had flown him over repeatedly to testify at trials. He had 
familiarized himself with the names of many of the key figures involved in the 
atrocities, but he had never come across Josipović (pronounced 
yoh-SIP-oh-vitch). He made a note to himself to find out what happened to the 
Serb officer.

MacQueen, who is sixty-eight, has spent the last three decades tracking down 
war criminals who have been hiding in the United States. His role, first with 
the Justice Department and then with Immigration and Customs Enforcement, has 
been to find offenders who made it into America posing as refugees. His 
official title is senior historian, but MacQueen’s job description is more akin 
to that of a police detective.

His obsession with war crimes has taken him overseas to interview survivors or 
obtain documents from authorities in Bosnia, Croatia, and Lithuania. Sometimes, 
it has meant knocking on the doors of unwitting suspects in the United States. 
But on many days, it has meant simply sitting in his office, not far from the 
Capitol, and examining one document after another from some three hundred 
thousand pages of records about the conflict that he has gathered.

It can be tedious work, MacQueen told me. A tiny phonetic mistake in a foreign 
dialect can imperil a case. MacQueen’s other preoccupation is building race 
cars. He uses the same detached precision to describe how he pieces together 
war-crimes cases as he does when explaining how he rebuilt an engine that blew 
out on his MG Midget during a recent race in West Virginia. Acts of mass 
killing can sound almost mundane as he recounts zeroing in on a suspected war 
criminal. “I guess it’s the banality of investigating evil,” he told me, a 
variation of Hannah Arendt <https://www.newyorker.com/tag/hannah-arendt> ’s 
famous phrase.

After finding Josipović’s name in the logs that day, MacQueen set out to learn 
what Josipović did during the war. Records listed him as an officer in an 
important logistics role at a time when the Bosnian-Serb Army was murdering 
eight thousand Muslim men and boys at Srebrenica, in what would become Europe’s 
first genocide since the Second World War. He didn’t appear to be a low-level 
triggerman but, rather, an officer who rose in rank and gained responsibility 
as the violence grew. Where Josipović lived now was unclear. MacQueen knew that 
someone with his record should not have been able to get into the United 
States. But he also knew that the immigration system in the late nineties had 
allowed hundreds of Bosnian wartime offenders to enter America amid a mass 
influx of about a hundred and twenty thousand Bosnian refugees. As a 
precaution, MacQueen searched for Josipović’s name in ICE’s databases. A hit 
soon came back—from Akron, Ohio. “Josipović had fallen through the cracks,” 
MacQueen told me. He realized that one of the highest-ranking Bosnian 
war-crimes suspects he had ever identified had been living quietly in the 
United States since 2003.

Federal agents with “ICE” emblazoned on their jackets, conducting workplace 
raids and taking undocumented immigrants into custody, have become a notorious 
sight under President Trump. But investigators at a separate ICE unit, where 
MacQueen works, who are largely removed from the raging immigration debate, 
have carried out a much less visible mission during the past nine years, 
targeting human-rights offenders who came to America from dozens of countries.

The immigration group, officially known as the Human Rights Violators and War 
Crimes Unit, currently has more than a hundred and thirty-five active 
investigations of suspected foreign offenders now thought to be living in the 
United States, officials said. In April, the unit’s investigation into a 
Liberian warlord living outside of Philadelphia, who had been implicated in 
murders, rapes, and enslavement in his native country in the nineties, resulted 
in a thirty-year prison sentence for immigration fraud and perjury—the longest 
criminal sentence in the team’s history.

Most of MacQueen’s cases have involved Bosnian Serbs, the group blamed for the 
bulk of the war crimes during the conflict, but his unit has also moved to jail 
or deport a number of Bosnian Croats and Muslims who were also accused of 
atrocities. He says more than fifty of the Bosnian immigrants he investigated 
have been forced out of the country. (Many cases have not become public, 
because they came in sealed immigration proceedings.) In January, after thirty 
years in the federal government, MacQueen officially retired, but ICE asked him 
to stay on for another five years as a private contractor, because his work on 
the Balkan front was “invaluable,” Lisa Koven, the chief of ICE’s human-rights 
law section, said.

MacQueen is determined to continue working on the investigations of the 
suspects he has already identified, and help prosecutors prepare to take them 
to court. His aim is to finish what he began and get as many war criminals as 
he can forced out of the country. “I don’t really need the money,” he said.

A native New Yorker, MacQueen comes across as soft-spoken and stoic, with a wry 
sense of humor, but he admits to losing his temper with suspects whom he 
believes are lying to him. In an angry confrontation a few years ago with a 
Bosnian woman in Wisconsin who concealed her involvement with a Serbian 
military unit, he used a vulgar sexual expression in Serbo-Croatian to show 
what he thought of her claims of innocence. A judge “gave me a little talking 
to,” MacQueen said. “I have a stunning lack of sympathy for anyone with an 
unclean record. They can go fuck themselves.”

I first interviewed MacQueen five years ago, about his earlier work in hunting 
Nazis. I was writing a book about the thousands of Nazi war criminals who came 
to America after the Second World War, and a source mentioned MacQueen’s role 
in breaking a critical case, in 1994, when he was at the Justice Department. 
For years, prosecutors suspected that a Lithuanian immigrant and naturalized 
American citizen in Massachusetts named Aleksandras Lileikis, who had led a 
special police force in Vilnius during the war, was a top Nazi collaborator who 
ordered the roundup of Lithuanian Jews in the nineteen-forties and turned them 
over to the Nazis for execution. But the Justice Department couldn’t prove it, 
and Lileikis denied any role in the massacres. “Show me something that I 
signed,” Lileikis had dared a prosecutor who showed up at his door, in Boston, 
in 1983.

The case languished for a decade, until MacQueen went to Lithuania to examine 
dog-eared Nazi records that had become available to Americans after the fall of 
the Soviet Union. MacQueen scoured the Lithuanian archives for days without 
success. Finally, he found a canvas-bound book with the names of nearly 
twenty-nine hundred wartime prisoners held in Vilnius typed in Russian. 
(MacQueen speaks six languages, including Russian, which he brushes up on by 
watching “The Americans,” on FX.) The logs listed hundreds of Jews, many of 
them children, who were jailed, turned over to the Nazis, marched to an 
excavation site six miles away, and methodically gunned down. In all, some 
sixty thousand Lithuanian Jews were massacred. In thick black ink at the bottom 
of an arrest order, MacQueen finally spotted the signature: Aleksandras 
Lileikis, chief of the special security police in Vilnius. Then he found twenty 
more signatures just like it.

Lileikis was ultimately stripped of his citizenship and returned to Lithuania, 
in 1996, where he died awaiting trial for war crimes. MacQueen considers this 
one of the most important achievements of his career. For years, he kept on his 
bulletin board in his office the Nazis’ neatly typed “execution cards” for two 
of the Lithuanian victims—a six-year-old Jewish girl named Fruma Kaplan and her 
mother. Lileikis’s men had jailed them after they were found hiding in a 
Catholic family’s home. Below Fruma’s name on the card was the local Nazi 
euphemism for what befell her and tens of thousands of others: Befehlsgemass 
behandelt—“treated according to orders.” MacQueen rarely displays much emotion 
over his investigations, but he had nightmares for years over victims like 
Fruma. “If you have any human sensibility, it sticks,” he told me.

MacQueen switched in 2004 to hunting for the perpetrators of war crimes in 
Bosnia. “The Nazis were all dying,” he said, and a new generation of war 
criminals were beginning to surface in the United States. In both eras, holes 
in America’s immigration system allowed offenders into the country based on 
little more than their word about what they did during the war. “We didn’t 
learn our lesson,” MacQueen said. “That the whole situation was allowed to 
repeat itself in Bosnia was historical amnesia.”

On July 11, 1995, Srebrenica, a predominantly Muslim enclave in eastern Bosnia 
that had been declared a United Nations protected safe area, fell to Bosnian 
Serb forces after U.N. and NATO forces did little to save it. Thousands of 
Bosnian Muslim men were bused to schools, warehouses, and other buildings that 
served as makeshift prisons. In the nearby village of Petkovci, soldiers from 
the 6th Infantry Battalion of the Bosnian Serb Army’s Zvornick Brigade herded 
more than a thousand Muslim men into hot, crowded classrooms. With no food or 
water, some prisoners “became so thirsty they resorted to drinking their own 
urine,” according to the U.N.’s International Criminal Tribunal for the former 
Yugoslavia. Shouting “Long live Serbia, Srebrenica is Serbian,” the soldiers 
shot some prisoners to death outside the school on July 15th, the tribunal 
found, then took the rest to a nearby dam and executed them, burying them in 
mass graves.

All told, the U.N. tribunal has implicated the 6th Infantry Battalion in the 
murders of more than a thousand Muslims from Srebrenica, at the school and 
elsewhere. Using Bosnian documents and U.S. government records, MacQueen 
managed to identify a handful of immigrants in Las Vegas, Phoenix, and 
elsewhere who served in the notorious unit. In 2014, he began focussing on 
Josipović. “I just kept finding more and more stuff on this guy,” he told me. 
The other 6th Battalion members he had found living in the United States were 
lower-level soldiers, but the logs placed Josipović several rungs above them, 
with a rank of company commander and the role of the chief logistics officer 
for the battalion in mid-1995. Piecing together Bosnian Serb Army personnel 
records from 1992 to 1995, he was able to track Josipović’s whereabouts in 
those years, his promotions in rank, and, most important, his senior role at 
the 6th Battalion headquarters in July, 1995, in Petkovci, at the time of the 
killings of the Muslims from Srebrenica. There were no eyewitness accounts of 
Josipović’s role, but MacQueen found documents that showed he had significant 
responsibility for a range of operations, including summoning the trucks needed 
to shuttle prisoners to the execution site and dispatching personnel to clean 
up the blood and waste from the school. Josipović “was a key functionary 
without whom mass-murder operations could not be carried out,” MacQueen told 
me. A former prosecutor in Bosnia, speaking on condition of anonymity, 
described Josipović as a “medium to big fish” in the Petkovci operation.

In 2003, Josipović settled in the United States. On the surface, his life 
looked like that of many other Bosnian refugees. He was married, with three 
children. He spoke spotty English, but held a steady factory job. He had a 
house and a mortgage in a blue-collar area of Akron near a local diner.. He’d 
received a few traffic tickets but had no major run-ins with the law.

In 2012, Bosnian officials asked the U.S. government to interview Josipović, 
because they thought he might have information that could help in their 
investigation into the 6th Battalion’s top commander, Ostoja Stanišić. F.B.I. 
agents questioned Josipović in Akron—not as a suspect but as a possible 
witness. He told them that he hadn’t served in the battalion and knew nothing 
about the commander. Two years later, MacQueen began his own investigation and 
learned about the F.B.I. interview. He was frustrated to read in the F.B.I.’s 
report just how easily Josipović had evaded scrutiny. Josipović “blew smoke” 
and “Bureau agents wrote it all down,” MacQueen said. The F.B.I. declined to 
comment on the case.

In September, 2014, MacQueen obtained a search warrant and, accompanied by four 
immigration agents, knocked on Josipović’s door. After the visitors showed 
Josipović their credentials, Josipović became agitated, but he agreed to answer 
some questions, MacQueen told me. The conversation started civilly, in English, 
but he began cursing in Serbo-Bosnian as questions turned to the war.

Josipović again denied serving in the military. MacQueen brought out the 
records showing Josipović’s name, rank, and identification number. “How do you 
square what you’re telling me with this?” he recalled asking. Josipović got his 
eyeglasses and began reading. He declared the records a forgery. “I don’t know 
who made this document,” MacQueen recalled him saying. It had been 
authenticated, MacQueen told him. Josipović’s story shifted. He had served in 
the 6th Battalion, he admitted, but he wasn’t in Pekovci. He had “granted 
himself leave,” he said, and was visiting relatives across the river in Serbia. 
MacQueen didn’t believe him. The bloodletting at Petkovci involved the entire 
unit, and Josipović’s name was in the officer staffing logs. MacQueen finally 
left, convinced that Josipović had been lying to American officials for more 
than a decade.

A military roster for the 6th Battalion of the Bosnian Serb Army’s Zvornik 
Brigade, from July, 1995, lists the name of Ilija Josipovic. War crimes 
investigators say members of the unit massacred more than a thousand Muslims 
from Srebrenica on July 15, 1995.

For two years, Josipović’s case was stalled owing to a backlog of immigration 
cases. Photos that Josipović posted on Facebook during that time show him 
smiling, his graying hair cropped short, as he posed with his children at a 
family wedding and at a graduation ceremony for his daughter with balloons in 
hand. Early last year, things changed. Federal prosecutors in Ohio charged 
Josipović with immigration fraud, and, three weeks later, just days after his 
sixtieth birthday, he walked into the federal courthouse in Akron. He had 
decided to plead guilty, which meant near-certain deportation. His wife, who 
came from Bosnia with him, had died of cancer two months earlier, and he was 
eager to take a deal rather than face more serious war-crimes charges. “I 
figured it was the easiest route to go,” he told the judge through a 
translator, before admitting he had concealed his military service in the 
Bosnian Serb Army. Prosecutors wanted the sure thing, as well. “This was 
someone we wanted to get out of the United States as soon as possible,” Jason 
Katz, the federal prosecutor who brought the case with MacQueen’s help, told me.

A deportation order came three months later. The U.S. Attorney’s Office in 
Cleveland put out a short press release, picked up by a few media outlets in 
Ohio, that said Josipović was being deported “for failing to disclose his 
involvement in a military unit engaged in war crimes in the former Yugoslavia.” 
The statement made no mention of his role as a ranking officer in the 6th 
Battalion or the unit’s involvement in the Srebrenica massacre.

ICE agents put Josipović on a plane back to Bosnia last summer. Boro Josipović, 
his thirty-one-year-old son, told me that it was “heartbreaking” for him and 
his two sisters, who all remained in Ohio, to see their father deported after 
fourteen years in America. His father had no real choice but to conceal his 
military service from U.S. immigration officials in his application papers, 
Boro maintained, or he and his wife and three children would never have been 
let into the country. “He just basically wanted to provide a better life for 
his family,” Boro said. “It was a civil war. From what I knew, he was just a 
regular officer.”

Josipović has been living with a cousin in Zvornik since his deportation, Boro 
said. I asked to speak to the elder Josipović, but Boro declined several 
requests to put me in touch with him directly and said his father was 
uninterested in being interviewed. His health has not been good, Boro told me, 
and “he doesn’t feel like talking about it.” Asked whether he thought his 
father was involved in war crimes, Boro Josipović said he did not really know. 
He has heard accounts of the Srebrenica killings, he said, ‘‘but there’s so 
many different stories. I really don’t know what happened. God only knows.’’

Bosnian authorities had told MacQueen that they would consider prosecuting 
Josipović on war-crimes charges. MacQueen was hopeful but not confident. Over 
the years, he had seen many suspects—both Nazis and Bosnians—escape the 
punishment he thought they deserved, and human-rights advocates have long 
complained of uneven justice for Balkan war criminals. The U.N. war-crimes 
tribunal for the former Yugoslavia, which closed last December, after 
twenty-four years, brought charges against a hundred and sixty-one higher-level 
offenders, including former Yugoslav President Slobodan Milošević, who died 
while on trial; the Bosnian Serb commander Ratko Mladić, the so-called Butcher 
of Bosnia, who oversaw the Srebrenica massacres; and the Bosnian Croat general 
Slobodan Praljak, who killed himself in court last year by drinking a vial of 
poison seconds after his sentence was affirmed.

But justice has been more erratic in the cases that have been brought before 
the Bosnian state court. MacQueen testified as an expert in state court in the 
joint trial of Stanišić, the 6th Battalion commander, and his top deputy, Marko 
Milošević (no relation to Slobodan), for crimes of genocide in the killings at 
the school in Petkovci and nearby dam. Stanišić was found guilty and 
imprisoned, but his deputy was acquitted because of what the court called a 
lack of evidence.

Trying accused war criminals remains politically contentious in Bosnia two 
decades after the conflict. The Bosnian Serb leader Milorad Dodik has called 
for a referendum 
<https://www.dw.com/en/bosnian-serbs-to-vote-on-state-court-system/a-18589788>  
to reject the authority of the state court, saying it is biased against Serbs. 
The state court has an enormous backlog and hopes to resolve 
<http://www.balkaninsight.com/en/article/bosnia-hopes-to-complete-war-crimes-cases-in-2023-02-23-2018>
  five hundred and fifty war-crimes cases involving more than forty-five 
hundred perpetrators by 2023. The Organization for Security and Cooperation in 
Europe, which monitors war-crimes trials in Bosnia, has observed a dramatic 
decrease in conviction rates in the state court in the past few years. A 2016 
report <https://www.osce.org/bih/247221?download=true>  by the group found that 
“many potential witnesses have died or emigrated” and acknowledged that it 
would be impossible to try every perpetrator: “Innumerable crimes were 
committed by innumerable people. Available resources render it impossible to 
prosecute all those who committed crimes.”

In the case of Josipović, a Bosnian prosecutor “reviewed the available 
evidence” and “issued an order not to initiate an investigation,” Boris 
Grubešić, a spokesman for the Bosnian state prosecutor’s office, told me. That 
will stand, he said, “unless we find some additional and sufficient evidence.”

Free for now from the threat of prosecution, Josipović has been trying to find 
work in Zvornik, without success, Boro said. Father and son talk on Skype when 
they can. MacQueen had heard nothing about Josipović for months after his 
deportation and didn’t know about Bosnia’s decision not to initiate an 
investigation. He expressed disappointment but was not altogether surprised. 
MacQueen’s main goal—getting Josipović deported—was accomplished. “We got done 
what we could do,” he said. “He’ll never be coming back.”

The Haunting Cries of Immigrant Children

ProPublica obtained an audio recording reportedly of crying children who had 
been separated from their parents and detained in a Customs and Border 
Protection facility in Texas. In the past two months, the government has 
separated almost two thousand immigrant children from their parents.
