Adelanto ICE facility's use of solitary confinement is among 10 highest in US, data shows

The immigration detention center closest to Los Angeles has placed dozens of people in solitary confinement each month since June, according to the most recent data from U.S. Immigration and Customs Enforcement.

In May 2025, the Adelanto ICE Processing Center had 14 people in isolation. When the Trump administration’s mass deportation effort revved up in June 2025, the number of detainees in solitary confinement there more than tripled. By July, it was 73; by August, 105.

The most recent data available shows that number went down slightly in January, to 74 people.

Ranked by percentage of the detainee population in “segregation,” as it is called at immigrant detention centers, Adelanto is among the U.S.’s top 10 facilities as of January, according to an LAist analysis of the most recent ICE data.

The data shows that of 229 ICE facilities that reported holding people since October 2024, between 50 and 60 usually reported putting at least one person in segregation in a given month. Out of the facilities that did place people in solitary confinement, Adelanto tended to do so less often than others until June 2025. (The facility held just a few people from October 2024 into January 2025.) When ICE’s presence increased in L.A. in June, the number of people sent to isolation in the facility also shot up — three to five times as many people have been isolated in Adelanto compared to the average facility that used any solitary confinement.

Since June, only two facilities have sent people to solitary confinement more times than Adelanto: one southwest of San Antonio, the other in central Pennsylvania.

Both of those facilities held twice the number of detainees as Adelanto on average from October 2024 through September 2025; but the number of people held in Adelanto since then has tripled, growing larger than either of the other facilities to hold an average of 1,800 people a day since October.

More on solitary confinement  

According to ICE, detainees may be placed in segregation for “disciplinary reasons,” or because of:

• “Serious mental or medical illness.”
• Conducting a hunger strike.
• Suicide watch.

The agency also says it might place detainees “who may be susceptible to harm [if left among the] general population due in part to how others interpret or assume their sexual orientation, or sexual presentation or expression.”

Not only is ICE holding more people in solitary confinement, but the agency's data also shows that detainees across the country are being isolated for longer periods of time. Detainees ICE considers part of the "vulnerable & special population" spent an average of about two weeks in solitary confinement each time they were isolated in 2022, when ICE first made the data available. By the end of 2025, the average stay in isolation had risen to more than seven weeks straight.

The GEO Group Inc., a private company that operates the Adelanto ICE Processing Center, has not responded to requests for comment.

How isolation can affect immigrant detainees  

UN human rights experts consider solitary confinement placements that last 15 days or more to be torture, though the U.S. Supreme Court has held that isolation doesn’t violate the Constitution.

The UN also maintains that solitary confinement should be prohibited for people “with mental or physical disabilities when their conditions would be exacerbated by such measures.”

In January, a coalition of immigrant rights groups filed a federal lawsuit on behalf of current detainees, calling for conditions at Adelanto to be improved. In addition to an unsanitary environment and a lack of healthy food and clean drinking water, detainees say solitary confinement is frequently used to punish those who speak out about conditions at the facility.

People held in immigrant detention centers are technically in “civil detention,” meaning that they are being detained to ensure their presence at hearings and compliance with immigration orders — not to serve criminal sentences.

According to the immigrant rights groups’ complaint, one detainee was placed in solitary confinement after complaining about the showers being broken. Another detainee said that, after asking a guard to “use more respectful language toward him, he was ridiculed, written up and given the middle finger by a guard who shouted, ‘Who the f--- do you think you are?’” Then, the detainee was placed in solitary confinement for 25 days.

Alvaro Huerta, the director of litigation and advocacy at the Immigrant Defenders Law Center who is representing detainees at Adelanto, told LAist that when people are placed in isolation at the facility, they’re typically in the same cell for 23 hours per day, unable to receive visits from their families.

For clients who are experiencing mental health challenges — especially those with suicidal thoughts — being placed in solitary confinement “can really exacerbate their condition,” he added.

In multiple statements to the media, ICE has said that the agency “is committed to ensuring that all those in custody reside in safe, secure and humane environments.” The agency has also said that detainees receive “comprehensive medical care” and that all detainees “receive medical, dental, and mental health intake screenings within 12 hours of arriving at each detention facility.”

Huerta called that “laughable.”

“We have countless examples of people who have said that this is not true, that they're not getting the medication that they're requesting, that they're not being seen for chronic conditions and emergency conditions,” he added. “And we know it's not true because 14 people have died in ICE custody this year alone.”
