ICE is claiming the computer ate its records the day after it was sued for abuse.

404 Media reports that after ICE’s Bridgeview Detention Center outside Chicago was sued October 30 for allegedly abusing detainees, the agency said that two weeks of video footage that could have shown how immigration detainees are treated in the facility was lost in a “system crash” on October 31.

“The government has said that the data for that period was lost in a system crash apparently on the day after the lawsuit was filed,” one of the lawyers representing detainees, Alec Solotorovsky, said in a Thursday hearing about the footage, according to 404 Media. “That period we think is going to be critical … because that’s the period right before the lawsuit was filed.”
