Police and sheriff’s offices across Southwest Florida shared their condolences for slain Charlotte County Corporal Elio Diaz, who was killed in the line of duty on Sunday.

Diaz was killed following a traffic stop at a Chevron gas station across from the Sunseeker in Charlotte Harbor, shortly after 3 p.m. on Sunday.

CCSO said that during the traffic stop, the shooter, Andrew Mostyn, 24, pulled out a rifle and opened fire on Diaz.

Deputies later located Mostyn near a Popeyes restaurant on Kings Highway. Mostyn grabbed for a rifle, and deputies fatally shot him.

During a news conference held late Sunday, Charlotte County Sheriff Bill Prummel gave a brief but heartwrenching statement regarding the loss of Diaz.

“I want everyone to keep Elio in your thoughts and prayers. He was a friend and a good family man, and he loved his children,” said Prummel. “He was a good cop, and he will be missed.”

Early Monday, the Lee County Sheriff’s Office expressed its condolences on the situation and offered aid.
