Eric Tran Thai, 36, pleaded guilty to two counts of possession of child pornography on Monday for incidents in which he sat in a stall in boys’ rooms at Boston Latin School in 2017 and surreptitiously took videos of students, the US Attorney’s office reported.

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 that was dropped in a superseding set of charges prosecutors filed on Monday.

According to court documents, Thai somehow managed to get into the school ten times between February and December 2017 to make his videos via a camera in a backpack he had placed 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 students in the restrooms and arrested him in March 2019. He faces state charges in Middlesex Superior Court for the BC incidents.
