The 24-year-old man that the Manatee County Sheriff's Office said shot and wounded a deputy Monday died of a self-inflicted gunshot wound, according to the autopsy.
There was no evidence of any other gunshot wounds.
According to officials, Ross Chrisman of Sarasota was found dead in his truck in the 5100 block of 33rd Street East in Bradenton.
Manatee County Lt. Bob Mealy was shot in the arm during an exchange of gunfire with a suspected bank robber, later identified as Chrisman.
Mealy, 52, continues to recover and is doing well. He has been with the Sheriff's Office since 1996.
According to authorities, Chrisman is believed to have walked into the Florida Bank at 3704 84th Ave. E around 11:30 a.m., displayed a gun and demanded money. He left in a white pickup truck.
Law enforcement responded to the scene, and Mealy spotted Chrisman's truck. A chase followed, and deputies used stop sticks to flatten the truck's tires, authorities said.
After the truck stopped in the 5100 block of 33rd Street E, deputies approached the vehicle and Chrisman fired a shot that struck Mealy, the sheriff's office said.
Deputies returned fire and multiple rounds were exchanged between Chrisman and deputies.
After a necropsy of the dog found in the truck, it is now believed that the animal died from the deputies returning gunfire. Initially, it appeared the dog had been shot by Chrisman.
