According to the Florida Highway Patrol, a driver found the body on Tuesday at 8:30 a.m. on the southbound side of I-95 near mile marker 127, which is north of Midway Road, when he pulled over with car trouble.

On Thursday, the St. Lucie County Sheriff’s Office identified the woman as Cindy Marie McDonald, 57, of Fort Pierce, and said her death is being investigated as a homicide.
