Lawyers for Kilmar Abrego Garcia on Wednesday continued their push to keep their civil case against the Trump administration alive, requesting to amend the lawsuit to include what they describe as the “torture and mistreatment” he experienced at El Salvador’s notorious mega prison, where he was wrongfully deported and held earlier this year.

In court documents filed in federal court in Maryland, Abrego Garcia’s legal team alleges the Salvadoran national “was subjected to severe mistreatment upon arrival” at the Center for Terrorism Confinement, “including but not limited to severe beatings, severe sleep deprivation, inadequate nutrition, and psychological torture.”

When Abrego Garcia arrived at the prison, his head was shaved and he was kicked and “struck on his head and arms,” which left “visible bruises and lumps all over his body,” according to the filing.

Abrego Garcia and 20 others were then made to kneel overnight, with prison guards striking those who fell, his attorneys said – “During this time, Plaintiff Abrego Garcia was denied bathroom access and soiled himself,” the filing added.

The lawyers describe where Abrego Garcia was first held as a windowless, “overcrowded” cell, with metal bunks without mattresses, “bright lights that remained on 24 hours a day, and minimal access to sanitation.”
