FRANKLIN COUNTY — A 19-year-old Florida man faces multiple felony charges in connection with multiple bomb threats against Sesser-Valier schools in Illinois.

According to the Franklin County Sheriff’s Office, Gabriel Isaiah Estrada, of Fort Walton Beach, Florida, made the threats in February 2016 and January 2017.

Estrada has been indicted by a Franklin County grand jury for making a false terrorist threat, disorderly conduct, intimidation of a minor, and harassment of a minor by electronic means.

He’s being held in a Florida jail and will be extradited to Illinois to face the charges.

Investigators say the case is complex and that Estrada will likely face more charges.
