The 9-1-1 call was harrowing.

A terrified woman in a pickup truck was screaming for help, pleading with the driver to let her out and let go of her hair. A man was heard threatening to throw her off a bridge.

And all of a sudden, the call went dead.

But sharp-witted Salem (Mass.) telecommunicator Michael Griffin kept his cool, quickly tracking down the woman and saving her from what could have been a far-worse fate.

The woman, whom the Herald is not identifying because she is a victim of a violent crime, and Robert Scribner, 43, were talking about their relationship in his pickup truck in nearby Marblehead on Sunday night when Scribner got upset, according to a police report filed in Salem District Court.

The woman wanted to get out of the truck but Scribner drove off – and she called 9-1-1.

‘Please don’t kill me,’ she said, according to the report.

Griffin answered the woman’s desperate call for help from inside that truck at 11:30 p.m.

The call looked like it was coming from a vehicle driving on Lafayette Street, according to the report, and the cops headed that way.

But the call got disconnected before Griffin got the vehicle’s make and model.

Griffin – a 25-year-old civilian dispatcher – jumped into action. He contacted the woman’s cellphone provider, T-Mobile, gave them her number and then followed her using the phone’s GPS. He got her name from the company, ran it through the department’s computer and saw she’d been involved in a domestic dispute with Scribner last year, according to the report.

Then, Griffin gleaned Scribner’s vehicle information from the Registry of Motor Vehicles’ computer records and put out an all-points-bulletin for the pickup, which was quickly found.

Salem Detective Lt. Conrad Prosniewski yesterday called Griffin a ‘smart kid who absolutely excels under pressure.’

‘That was good police work from a dispatch point of view. He pushed all the right buttons at the right time and got the answers as quickly as possible,’ Prosniewski said.

‘She was terrified during the ride,’ Prosniewski added.

Scribner, of Marblehead, was charged with domestic assault and battery, kidnapping and threats to commit a crime. He pleaded not guilty and he’s being held until a dangerousness hearing Friday.

‘He did his job,’ Prosniewski said of Griffin. ‘And he did it damn well.’
