David Brown, 33, was killed at Hennessy’s Bar and Grill, 127 Forest Lakes Boulevard in Oldsmar, Florida, on February 15, 2017. Brown, an employee at the bar, was found inside suffering from multiple gunshot wounds and was pronounced dead at the scene. The Pinellas County Sheriff’s Office responded and opened an investigation.

The investigation identified 43-year-old Brian Mytych, a former Michigan police officer, as the person who told deputies he had shot Brown. According to reports, Mytych had been involved in an earlier altercation at the bar on February 6, 2017, when he was issued a trespass warning and arrested for disorderly intoxication after refusing to leave. Witnesses said Mytych returned in the early hours of February 15, was asked to leave again, came back with a handgun and shot Brown multiple times. Patrons were ordered to leave, Mytych called 911 himself and was taken into custody without incident; a .45 caliber handgun was recovered and he was charged with one count of first-degree murder.

Are there witnesses or information about the February 6 interaction or the events inside the bar on February 15 that haven’t been shared publicly?
