A juvenile accused of making homemade bombs is being held in a juvenile facility in the Alexandria, La., area, Concordia Parish Assistant District Attorney Brad Burget said Thursday.

A custody hearing was held Monday after the 16-year-old boy was arrested in Vidalia, Burget said.

The boy was arrested Jan. 24 by the Adams County Sheriff’s Department after his stepmother found four homemade bombs in his room, sheriff officials said at the time. One of them was in a book that had pages carved out to fit the bomb.

The Vidalia police arrested the boy because at least one bomb was probably built in Vidalia, the teen’s current residence.

“The investigation led us to believe (he) manufactured the bomb in Louisiana,” Burget said.

Monday’s hearing was to decide whether or not to release the boy to his parents’ custody. He was denied release, Burget said.

A status hearing is set for Feb. 12, Burget said.

“It’s to see whether or not the juvenile will still be a danger or if he should be released to his parents,” he said. “The judge ordered some psychiatric testing to see whether or not the juvenile was stable enough to be returned to his parents.”

The juvenile had moved out of his father and stepmother’s Adams County house and into his mother’s Vidalia house when the bombs were found, Maj. Jody Waldrop, investigator for the Adams County Sheriff’s Office, said last week.

The boy’s mother was cleaning his room when she found a book containing a bomb between his mattresses, Waldrop said.

The Vidalia Police Department and Concordia Sheriff’s Office searched the juveniles’ current residence and Vidalia High School, but no other devices were found, Waldrop said.

The devices were “capable of doing harm to human beings,” he said, and the Adams County Sheriff’s Office detonated them soon after they were recovered.

The juvenile was allegedly upset with a grade he’d received, Waldrop said, but at the time of his Adams County arrest, law enforcement had no reason to believe he intended to harm anyone.
