Salem, Mass., police are crediting “outstanding” work by a quick-acting police dispatcher with potentially saving a woman’s life late Sunday night.

Police received a frantic 911 call from a woman, a passenger in a pickup truck, who was screaming for help. When the call disconnected abruptly, the dispatcher used the phone’s GPS to track the truck until police caught up with it on Margin Street, the Salem News reports.

Police arrested Robert Scribner, 43, of 10 Taft St., Marblehead, on charges that include kidnapping, threats to commit murder, and domestic assault and battery.

Scribner, who pleaded not guilty to the charges at his arraignment yesterday in Salem District Court, is being held without bail pending a dangerousness hearing scheduled for Friday.

Salem police Lt. Conrad Prosniewski credited a civilian dispatcher in the department for locating the suspect. “Mike Griffin, our dispatcher, did an outstanding job coordinating the search,” Prosniewski said.
