Matthew Skye Keister, 19, of Hollywood, Maryland, was last seen on January 20, 2025, and stopped communicating with family and friends on January 21. Concern grew and he was reported missing to the St. Mary’s County Sheriff’s Office on January 26.

Deputies responding to an EMS call at Keister’s home in the 25000 block of Jones Wharf Road found his body concealed in a trash can on the property on January 27. An autopsy at the Office of the Chief Medical Examiner in Baltimore determined the cause of death was a gunshot wound to the head, and the Criminal Investigations Division opened a homicide investigation.

Investigators focused on a known associate, Lee L. Richardson, and say Richardson shot Keister inside the residence, attempted to clean the scene, and disposed of the body. An arrest warrant for Richardson was issued January 30, 2025, and he was taken into custody by the U.S. Marshals Fugitive Task Force in Prince George’s County.

If anyone knew Matthew or saw activity at the Jones Wharf Road residence around January 20–27, please share what you know with investigators.
