FAIRFAX CITY, VA — The City of Fairfax Police arrested a Fairfax County Sheriff's deputy Tuesday afternoon in connection with an alleged sexual assault of a female prisoner that occurred Monday morning. Patrick D. McPartlin, 45, of Warrenton is being held at the City of Alexandria Adult Detention Center.

McPartlin allegedly sexually assaulted a female prisoner in a parking lot located in the 11000 block of Fairfax Boulevard while transporting the woman from the Fairfax County Adult Detention Center to the Loudoun County Adult Detention Center in his department-owned vehicle, the Fairfax City police said Tuesday.

Fairfax City police detectives identified McPartlin and secured warrants for two counts of object sexual penetration. McPartlin is being held on no bond.

The victim reported an assault when she arrived in Leesburg around noon Monday, Sgt. Matthew Lasowitz of the Fairfax City police told the Washington Post. Loudoun sheriff's deputies conducted an investigation and then referred the case to the Fairfax County Police Department, which determined that the alleged assault occurred in Fairfax City.

McPartlin, who has been a Fairfax County deputy for 21 years, was taken to the Alexandria jail because of a Fairfax County policy that former employees should not be held in the Fairfax County jail. McPartlin resigned from the Fairfax County Sheriff's Office Tuesday shortly after being served his termination papers, the Post reported.



In February 2015, McPartlin was among a team of deputies who tried to remove Natasha McKenna from her cell in the Fairfax County jail to transport her to the Alexandria jail, according to the Washington Post. The 37-year-old woman, who had schizophrenia and other disorders, was shocked four times with a stun gun to bring her under control while she was shackled. She died several days later at a hospital.

The Fairfax County prosecutor ruled that the deputies involved in McKenna's death did not commit a crime. In 2018, the Fairfax sheriff's office paid her family a $750,000 settlement.
