Officer Charles Kondek, a 45-year-old married father of six, was killed in Tarpon Springs, about 48 kilometres northwest of Tampa, after responding to a noise complaint around 2 a.m. ET, the local police department said.

Authorities charged Marco Antonio Parilla Jr., a 23-year-old released from prison in March and wanted for an alleged probation violation, with the first-degree murder of the officer.

Kondek had responded to a 911 call and encountered Parilla, who was at the apartments looking for someone he believed had reported him for violating his probation, Pinellas County Sheriff Bob Gualtieri said.

Parilla fired shots from a .40-caliber handgun, hitting Kondek in the upper body with one round, Gualtieri said. The suspect then ran over the officer as he drove off from the scene, according to the sheriff.
