MARION COUNTY, S.C. (WBTW) — Marion County authorities are continuing to look for leads in a 2-year-old double homicide investigation.

Cathy Diane Thompkins, 45, and John Michael Thompkins, 49, were found dead by deputies on the night of Oct 3, 2021, after someone called 911 and reported hearing gunshots, the Marion County Sheriff’s Office said. Their dog Tipsy was also found dead from a gunshot wound inside a mobile home in the 3500 block of Ervin Court in the Blue Savannah Community.

According to a sheriff’s office incident report, when deputies arrived they talked to a neighbor who reported hearing six gunshots in the area. Another neighbor later told deputies that he heard gunshots and then saw three people dressed in black run away from the home and then drive off in a dark-colored car.

John Thompkins was found dead by deputies in a rear hallway of the home, the report said. Cathy Thompkins and the dog were both found dead in a front room of the home. Deputies recovered shell casings on the front porch and in the hallway and front room where the bodies were found.

Anyone with information is asked to call 843-423-8399 or leave an anonymous tip at Crime Stoppers of the Pee Dee by calling 1-888-CRIME-SC. (274-6372). Information that leads to an arrest might be eligible for a Crime Stoppers reward.
