A suspect in the shooting death of a woman on I-20 and I-285 on Monday has been charged with felony murder and aggravated assault.

Corey Deshun Jones, 28, was booked into the Fulton County Jail around 1 p.m. Tuesday after a short stay at Grady Memorial Hospital Tuesday morning.

Atlanta police spokeswoman Elizabeth Espy said she did not know why Jones was taken to the hospital.

Police were called to I-20 westbound near I-285 southbound around 3:40 p.m. on Monday after a passerby called 911 to report an incident, Atlanta police Capt. Paul Guerrucci said.

They found 25-year-old Tyana Boyd shot in a silver Volkswagen Passat that was pulled over to the left shoulder. Two left lanes of I-20 westbound were closed as part of the investigation, backing up traffic for hours.

Boyd was taken to Grady, where she died.

Police said they believe Boyd and Jones were outside the vehicle when the incident occurred.

Police have not determined a motive and the investigation is continuing.
