UPPER MARLBORO, Maryland. – A Prince George's County elementary school teacher accused of sexually abusing minors and possessing child pornography remains in custody after his attorney waived a bail hearing Wednesday.

Mark Cobb, 44, is accused of having a year-long texting relationship with a nine-year-old schoolgirl and of requesting and receiving explicit photographs.

According to police, Cobb confirmed the details of the relationship during questioning on Monday.

His next court date is a preliminary hearing scheduled for September.

Prosecutor Aisha Braveboy expressed her outrage at the allegations, calling the situation “beyond imagination.” She praised the young girl for her courage in revealing herself and stressed the importance of protecting children from people they trust.

“I'm so proud that she spoke out,” Braveboy said. “But this is no different than other cases involving young victims. Sometimes they don't understand what's happening to them. They're confused. These are people who are in positions of trust. So she had a right to trust her teacher.”

“I can't imagine how sick a person has to be to have a conversation like that, a sexually explicit conversation with a nine-year-old. It's outrageous. But our job is to get justice, and that's what we're going to do,” Braveboy continued.

During a search of Cobb's home, authorities discovered pictures and videos of other abused children.

The investigation to identify these children is ongoing and Braveboy's office urges any additional victims to come forward.

Cooper Lane Elementary School, where Cobb was employed, sent a letter to parents calling the allegations “disturbing” and assuring families that the school was fully cooperating with authorities.

The school principal also encouraged parents to talk to their children about online safety.

A lawyer for Cobb has not responded to requests for comment.
