A former Georgia deputy was sentenced to life in prison for murdering his married girlfriend because she insulted his penis size, The Independent reports.

Police say, Jason Cunningham, 48, shot Nicole Harrington, 37, in the back of the head in a parking garage elevator in Augusta, Georgia, in June 2020.

Cunningham became enraged after Harrington insulted “the size of his manhood,” according to Augusta District Attorney Jared Williams in a statement.

After an eight-hour standoff with Columbia County deputies at a boat ramp at Clarks Hill Lake, Cunningham was finally arrested.

Cunningham was sentenced to 30 years in prison on Monday after pleading guilty to murder and five years for possession of a firearm during the commission of a felony.

According to an affidavit obtained by WRDW, Cunningham claimed he went to meet Harrington to end their affair.

Cunningham resigned from the Richmond County Sheriff’s Office in 2018 after testing positive for an illegal substance while on duty, according to WFXG. He previously worked as a marketing manager for Forces United, a veterans support organization based in Georgia.

Harrington, of Florida, left behind three children.
