It was a "janky" handgun, one that seemed badly put together, but Jason Youngmark was hoping to sell it anyway, according to court documents.

On March 10, at a gathering at a north Minneapolis duplex, he took a potential customer into a stairwell to show him the silver .357 Magnum. Moments later, partygoers heard a loud "pop." They found Youngmark on the ground at the bottom of the stairs, his eyes rolling back into his head, a bullet wound to his chest.

Criminal charges filed late Friday say the defective gun suddenly fired as Ike Wilson Jr. held it, killing Youngmark, 33, a husband, father of seven and stepfather of one. Wilson, of the 2600 block of Girard Avenue N., Minneapolis, was charged with second-degree felony manslaughter and a felony count for having a gun. He faces as long as 25 years in prison and fines of $50,000.

He's in the Hennepin County jail.

Officers found the gun lying next to Youngmark. A forensic examination revealed "defects that are consistent with firing pin hits that did not result in the discharge of a cartridge," according to the complaint.

Wilson left the duplex soon after the shooting, telling the homeowner and a witness that he didn't know what happened, according to the criminal complaint. Later, he told a friend that he had pulled the trigger repeatedly and that nothing had happened, but then the gun just "went off," the complaint said.

Wilson also called Youngmark's father, Jerome Arradondo Sr., to apologize. Arradondo urged Wilson to turn himself in and, on March 17, relatives and community activists held an afternoon vigil urging the same.
