It took a driver, his pickup truck and some quick thinking to stop a gay Atlanta man, a habitual drunk driver allegedly so tanked that he was dozing off as he drove through Roswell.

Roswell police say Matthew Henry Perrick, 25, was under the influence of several substances when he was finally arrested on July 22. Now, he faces a trio of felony charges, including DUI, driving as a habitual violator and possession of a controlled substance. He remains in the Fulton County jail on $5,000 bond for each charge.

WSB first reported the story of how Brian Cooper, dubbed a good Samaritan for his actions, spotted Perrick driving erratically on Johnson Ferry Road in Cobb County.

“These days with people distracted driving, I thought maybe he was texting or speeding or not really paying attention,” he said.  “It quickly became apparent that he was incapacitated, like had no business on the road.”

Cooper said he followed Perrick into Roswell with police on the phone, and witnessed Perrick drive off the road and nearly hit two people out walking their dog.

So without a police officer in sight, Cooper tells WSB it was time to take action when Perrick's vehicle left the road.

Cooper said he found an opening, and positioned his truck in front of Perrick’s car, preventing him from driving any further.

“I got out, asked him if he needed any help, he didn’t respond, so I took his keys out of his ignition,” he said. “I figured I’ve got an old truck, if he hit it, it wouldn’t be the worst thing.  I was just trying to make sure he didn’t hit somebody else.”

Perrick has been arrested in Fulton at least three times since 2010 – once for simple battery and twice for DUI. WSB reports that Perrick has faced DUI charges at least seven times since 2009.

Maybe Perrick should follow his own advice. In a July 15 Facebook post, he recommended an app for Atlanta taxis.
