March 19 (UPI) -- A Mexican teenager died earlier this week at Florida's Glades County Detention Center, U.S. Immigration and Customs Enforcement officials said, becoming the youngest person to die in federal immigration custody amid the Trump administration's immigration crackdown.

The teen, 19-year-old Royer Perez-Jimenez, was found unconscious and unresponsive in a facility dormitory by a detention officer at 2:34 a.m. EST Monday, ICE said in a Wednesday statement.

Medical staff performed CPR but were unable to resuscitate the teen, according to officials, who said he was pronounced dead at 2:51 a.m.

The cause of death is under investigation, but ICE said it believes he died by presumed suicide.
