According to the Pinellas County Sheriff's Office, the shooting happened just after 1 a.m. at Hennessey's Bar and Grill located at 127 Forest Lakes Boulevard.

The two had an altercation Feb. 6 at the bar, according to officials.

"The fight transpired over the suspect being disorderly inside of the bar," Gross said. "And making racial slurs to musicians performing at the bar."

Detectives with the Robbery/Homicide Unit said Mytych walked into the bar, which was still crowded, and was told to leave. He returned a short time later and shot Brown multiple times. Mytych, who lives in Tarpon Springs, then ordered everyone out of the bar and he then called 911.

Mytych was taken into custody without incident and he has been charged with one count of first-degree murder.

According to officials, Mytych was previously employed at the Detroit Police Department for five years. He then went on to work at Westland Police Department in Westland, Michigan for 13 years before he was terminated.
