Andrew Mostyn Jr., 24, has been identified as the person who fatally shot Sheriff’s Deputy Sgt. Elio Diaz during a routine traffic stop at a Chevron gas station on Tamiami Trail across from the Sunseeker resort around 3 pm on December 15.
According to Sheriff Bill Prummell, Sgt. Elio Diaz was conducting a routine traffic stop when he pulled over a white pickup truck. Andrew Mostyn, the driver of the truck, used a rifle to open fire, killing him at the scene.
A manhunt ensued, leading deputies to Mostyn’s pickup truck parked near a Popeyes restaurant on Kings Highway, close to I-75. As deputies closed in on Andrew Mostyn, he reportedly reached for another rifle inside his vehicle. In response, a deputy fired a fatal shot to Mostyn’s head.
Andrew Mostyn was airlifted to a hospital, where he succumbed to his injuries. At the scene of his confrontation with deputies, Mostyn had his dog with him. The animal is now in the care of a local animal shelter.
Sheriff Prummell described the incident as a tragic and senseless act of violence, emphasizing the ongoing investigation to determine what led Mostyn to commit the crime.
