JACKSONVILLE, Fla. -

Juanita Jordan has pleaded guilty to second-degree murder for her involvement in the June 2012 shooting death of 26-year-old Marvette Littles in what prosecutors say was a case of mistaken identity.

Prosecutors say Jordan walked up to Littles’ car, which was stopped at a traffic light on University Boulevard, and shot into the rear passenger window of the vehicle.

Littles (pictured with family, below) was in the driver’s seat when she was struck by a bullet in the torso area.

Littles’ 8-month-old daughter and fiancé were in the vehicle at the time of the shooting and were not hurt in the incident.

After the shooting, Jordan limped away from the crime scene. With help from the community, the Jacksonville Sheriff’s Office tracked down and arrest Jordan.

Littles did not know her killer. Jordan believed someone she knew was in Littles’ car.

After the plea, Judge Adrian Soud sentenced Jordan to 50 years in prison.
