A Tucson woman accused in a 2012 killing has pleaded guilty to manslaughter.
Ashley Marie Antone was accused of stabbing and killing Kaitlin Chico in May 2012.
Antone and boyfriend Emmanuel Arie Rivera were driving in a car with Chico when motorists called 911 to report seeing the three fighting.
Responding police located the car, driven by Emmanuel, and followed it. Other officers located Chico's body in a neighborhood alley from where the car was seen fleeing.
Antone was originally charged with second-degree murder. She's scheduled for sentencing on June 23.
