Frank Wilson, 68, a Gresham, Oregon business owner and U.S. Army veteran, was last seen on September 22, 2015. He was married for 44 years and was a father and grandfather; those who knew him described him as practical, sharp-witted and generous.

On September 24, 2015 his body was found inside his white pickup truck parked at Trillium Lake Sno-Park east of Government Camp on Mount Hood. The Oregon State Medical Examiner’s Office ruled the cause of death a gunshot wound to the chest and classified the death as a homicide. The Clackamas County Sheriff’s Office opened an in-depth investigation and appealed to the public for information.

The case remains an open investigation and a cold case for the family and community.

If anyone has information about Wilson’s movements in the days before September 22, 2015, or about activity at Trillium Lake Sno-Park that weekend, please come forward.
