FORT PIERCE, Fla.
Investigators are saying that an early morning fire at the mosque attended by Omar Mateen, the shooter in the Orlando nightclub shooting that claimed the lives of 49 people, was set intentionally.
St. Lucie County Sheriff's Office received a call around 12:30 Monday morning that the Islamic Center of Fort Piece was on fire.
St. Lucie County Fire District crews responded and put the fire out.
Investigators say a video was captured at the mosque shows an individual approached the east side of the building just moments before a "flash" is seen and the fire starts.
The sheriff's office is actively investigating this as an arson with the assistance of the St. Lucie County Fire Distrcit, the Florida State Fire Marshall's Office, the Bureau of Alcohol, Tobacco and Firearms and the Federal Bureau of Investigations.
