A volunteer aide at a suburban Maryland elementary school is facing federal child-pornography charges after prosecutors say he made videos of children having sex with him and each other.

Twenty-two-year-old Deonte Carraway faces life in prison if convicted of the eight federal charges. He's also been charged with child sexual abuse in state court. Prosecutors say he has admitted making the videos.

Police have identified 17 victims and say there may be more. The allegations against Carraway have already prompted lawsuits and shaken parents' faith in county school administrators. Authorities say Carraway made many of the videos on school grounds during the school day.

The school's principal has been placed on leave. According to the lawsuits, she didn't follow up on complaints about Carraway and didn't go directly to police when she was shown one of the videos.

Federal prosecutors are set to detail the latest allegations in a widening child pornography scandal at a suburban Maryland elementary school.

Prince George's County police say 22-year-old Deonte Carraway abused at least 17 children. According to police, he made sexually explicit videos of children at Judge Sylvania Woods Elementary School in Glenarden, where he worked as a volunteer teacher's aide. Carraway's public defender declined to comment Tuesday.

Parents of victims have alleged in lawsuits that the school's principal was warned about Carraway's conduct but did nothing. The principal has been placed on leave.

Police say Carraway also victimized children at a church, a pool, a community center and several homes.

Maryland's U.S. attorney and other law enforcement officials will discuss the allegations against Carraway at a news conference Tuesday afternoon.
