What was published
K99 Hits reported that Upper Seven Law, a Montana firm, estimates more than 250 immigration-enforcement arrests in the state in 2026 involving ICE and Customs and Border Protection. The same story says a federal judge ordered 24 people released from the Cascade County Detention Center after finding officers had not taken the legal steps required before keeping them in custody. The firm traces that litigation to the warrantless Border Patrol arrest of Jesus Hernandez near Lewistown. Upper Seven litigation director Molly Danahy told KTVQ, “All we’re doing here is asking the government to follow its own laws.” The firm says its cases have led to 40 releases. Danahy said the firm did not have a complete CBP arrest record until the court cases began.
Where it stands
There is no official statewide arrest total in this item. The 250 figure is the firm’s estimate. The 24-person release is a reported court order, not a count of everyone held.
Does not establish
This is not a detainee locator. It does not list people in civil immigration custody, and it does not map upcoming enforcement. Court filings and ICE’s own detention statistics are the records to read next. A law firm’s tally is advocacy-adjacent even when the underlying dockets are real.
