Update for Aug. 29
A few more details from a followup conversation with KCSO Sgt. West:

Detectives are still leaning towards the probability the victim shot himself in the upper groin area based on physical evidence and the bullet's trajectory.

The victim refused to tell detectives what happened and no gun was found at the scene.

According to Sgt. Cindi West with the King County Sheriff's Office, a man in his twenties was shot in the leg on the 9600 block of 11th Ave S.W. (White Center side of Roxbury) on the evening on Aug. 28.

The victim had powder burns on his pants, a hole in his left front pants pocket, and a bullet hole in his upper left groin, leading deputies to investigate the "very likely" possibility the wound was self-inflicted, West said.

Witnesses at the scene claimed they saw a white Jeep leaving the scene, so deputies are investigating the possibility of a shooter as well.

This story will be updated with more details as they become available.
