Authorities have identified the woman who was shot and killed while she waited at a Dunkin' drive-thru Tuesday morning while her 11-year-old son was in the vehicle.

The Montgomery County District Attorney's Office said 35-year-old Rachel King of Elkins Park was shot multiple times while behind the wheel of her SUV.

It happened around 7:40 a.m. in Cheltenham Twp.

According to investigators, King was driving westbound on Cheltenham Avenue when she turned into the Melrose Shopping Center, then pulled into a line of traffic in the Dunkin' drive-thru lane.

The D.A.'s office said a light-colored sedan, possibly a Ford or Mercury, was seen driving directly behind King.

District Attorney Kevin Steele said this appears to be a targeted murder. He said the suspect did not try to open the door or communicate with King before firing.

King was a teacher at Grover Cleveland Elementary School in the Mastery charter school system in Tioga-Nicetown..

Anyone with information is asked to contact the Cheltenham Township Police Department at 215-885-1600 (extension 400) or Montgomery County Detectives at 610-226-5553.
