A former Mount Paran Christian School teacher facing sex charges involving students was denied bond Monday morning in Fulton County, according to Channel 2 Action News.

Christopher Brown, who was wanted on multiple charges in Marietta and Roswell, turned himself in to the Cobb County Sheriff’s Office on Friday night.

Brown taught high school physics, chemistry and computer science at Mount Paran in Kennesaw until he was fired Oct. 4.

In Marietta, he faces charges of sexual assault by a teacher and influencing a witness, Marietta police spokeswoman Officer Brittany Wallace said Friday. In Roswell, he is wanted on a charge of enticing a child for indecent purposes.

Brown, 37, of Marietta, allegedly had sex with a 17-year-old Mount Paran student in late July. Marietta police learned of that alleged incident from authorities in Roswell, where Brown is accused of kissing a 15-year-old Roswell High School student, Wallace said.

According to a Roswell arrest warrant, Brown, who is married, met the 15-year-old at a Starbucks on Crossville Road on Sept. 28 and drove her to a nearby park, “where the two kissed.” He was the student’s tutor, police said.

While under investigation in Roswell, Brown allegedly sent a text message to a friend of the 17-year-old Mount Paran student. In the text, Brown asked the friend to contact the girl “to make sure we’re on the same page with our story,” Marietta police Detective Mark Erion said in a warrant.

In a statement, Mount Paran headmaster David Tilley said Brown was terminated “immediately after the school learned that he had committed a violation of the standards of our Christian community."
