A sheriff's deputy from Fairfax County was charged on Tuesday for sexually assaulting an inmate in his custody.

Patrick D. McPartlin, 45, a Warrenton resident was arrested for object sexual penetration after he assaulted a female inmate in a county-owned vehicle while he was transporting her from the Fairfax County jail to the Loudoun County jail, the Washington Times reported.

In his 20 years of working at the sheriff's office, McPartlin had a history of involving himself in fatal incidents such as in 2016 when he fatally shot a hospital patient who was suffering a mental episode outside Inova Fairfax Hospital.

In 2015, he was part of a team of deputies that shot Natasha McKenna, mentally ill inmate, multiple times with a stun gun to restrain her.
