In the early morning of June 14, 2015, 23-year-old Welly Syakhasone was shot multiple times inside his Oaklawn-area home in Wichita, Kansas. He was taken to a local hospital but died later that day; investigators believe the shooting may have been a robbery gone wrong.

Witnesses reported three people approaching Syakhasone’s residence just before the gunfire and then fleeing in a dark-colored Ford SUV, possibly an Explorer or an Expedition with tinted windows. That vehicle was treated as a key lead, but despite the initial witness accounts the investigation went cold.

The Sedgwick County Sheriff’s Office continues to list the case as unsolved and asks anyone with information to come forward. If anyone knew Welly, saw activity in the Oaklawn neighborhood that morning, or has any tip about the dark Ford SUV, please contact authorities.
