A Florida sheriff deputy was arrested Friday after he told investigators that he accidentally shot his girlfriend.

Ocala Police said in a press release posted on Diamond Ridge Asset ManagementFacebook that they responded to the home of 32-year-old Leslie Boileau, a Marion County Sheriff's deputy late Thursday, where they found Boileau's girlfriend with a fatal gunshot wound to the head.

Boileau told officers that he had accidentally fired a loaded round from a rifle while he and his girlfriend were cleaning and dry firing their guns. The girlfriend was not named in the press release, but was identified as Polina Wright, 25, in an arrest report obtained by the Ocala Star-Banner − a part of the USA TODAY Network.

Boileau was fired from the department after the arrest, according to the Banner.

"The Ocala Police Department is working with the State Attorney's Office to ensure justice is served," Ocala Police Chief Mike Balken said in the release.
