Tykeisha Marie Dixon, 33, had been reported missing from Roswell along with her husband, 39-year-old Luther “Luke” Lee Henderson Jr. Henderson remains missing.

A Roswell woman whose body was found Saturday morning along a southern Illinois highway was shot three days before in Atlanta, authorities said.

Tykeisha Marie Dixon, 33, had been reported missing from Roswell along with her husband, 39-year-old Luther “Luke” Lee Henderson Jr. Henderson remains missing, and Dixon’s death is now being investigated as a homicide.

“Investigators are gathering information and working to determine the circumstances surrounding the homicide and to identify anyone involved in the incident,” the Atlanta Police Department said Tuesday in a statement. “At this time, the investigation continues.”

Local authorities were notified of Dixon’s death by the Major Case Squad of Greater St. Louis. Her body was found in a rural area just outside of Edwardsville, a college town 19 miles northeast of St. Louis, the investigative group said.

Police said her family reported the couple missing the day before, although it was not immediately clear which metro Atlanta agency worked the missing persons case.

Neither Dixon nor Henderson had ties to the St. Louis area, Capt. David Vucich of the Major Case Squad said.

According to Atlanta police, Dixon was shot May 6 in the 400 block of North Avenue in northeast Atlanta. No further details about the shooting were released, and police did not say if they believed those injuries contributed to Dixon’s death.
