Eric Tran Thai, 36, pleaded guilty to two counts of possession of child pornography on Monday for incidents in which he would sit in a stall in boys' rooms at Boston Latin School and surreptitiously video students in 2017, the US Attorney's office reports.

Thai is now scheduled for sentencing on May 13 on two counts of possession of child pornography. He had initially also been charged with sexual exploitation of minors, but those charges were dropped in a superseding set of charges prosecutors filed yesterday.

According to court documents, Thai somehow managed to get into the school ten times between February and December, 2017 to make his videos of students in adjacent stalls - via a camera in a backpack he'd place on the floor near a stall separator - or at urinals.

Following his arrest for similar alleged activity at Boston College in 2018, investigators found 45 videos of male Boston Latin School in the restrooms and arrested him in March, 2019.

He faces state charges, in Middlesex Superior Court, for the BC incidents.
