Lexington County deputies have charged three teens with possessing an explosive device last week at a school while students were not present.

Dylan Hank Maples, 19, and Ted William Miller, 18, are charged with possession of an explosive device, according to arrest warrants. The third teen, whose name will not be released because he is under age 18, is charged with the same crime.

“Based on information detectives have confirmed during their investigation and interviews with the suspects, the three teens took a sealed Mason jar containing gasoline that featured a T-shirt as a fuse to Pleasant Hill Elementary School Jan. 29,” Lexington County Sheriff Jay Koon said. “They climbed up on top of the school and threw the device on the parking lot, which caused an explosion.”

The three teens turned themselves in Monday night after seeing a social media post and news coverage about the incident, according to Koon.

Maples and Miller were arrested and booked into the Lexington County Detention Center. The third teen was released to his parents. His case will be heard in Lexington County Family Court.
