Blake Randall Wardell, 25, was congregating with friends in a house's garage in the wee hours of the morning when he donned a bulletproof vest.
Then Wardell asked his 18-year-old friend Taylor Ann Kelly to shoot him, according to the Anderson County Sheriff's Office in South Carolina.
Kelly complied. But the small-caliber bullet hit above the kevlar portion of the vest and then went into Wardell's heart, killing him, Anderson County Deputy Coroner Don McCown told WYFF-TV in Greenville.
CPR was being attempted on Wardell when authorities arrived at the scene about 2:40 a.m; EMS personnel confirmed Wardell was dead.
Kelly was charged with involuntary manslaughter which could carry a five-year prison sentence if she's convicted. She was being held in jail pending a bond hearing.
