TULSA, Oklahoma - A Tulsa man survived a rollover collision while several people rushed to his aid; but Tulsa Police said one of them stole the victim’s wallet and took more than $1,000 from him.

Police said thieves prey upon people at their most vulnerable, and this isn't the first time someone has stolen from the victim of an accident.

Patrick Briscoe is in critical condition, clinging to life, after a semi-truck hit him and caused him to roll of Highway 412 on September, 1.

His mother, Debra Fields, said "It was just by the grace of God that he's with us."

She said he bled out, had his spleen removed, repaired his colon and liver; he also broke his pelvis and legs.

If that wasn't misfortune enough, someone at the scene stole his wallet and drained his bank account.

"Why would you do that? And, give it back to us. And, that, that was a pretty low thing to do. Somebody's already down and out and having misfortune, and I hope that they regret what they did," Fields said.

She said, the day of the accident, her son withdrew $400 from an ATM.

Someone took that cash, his driver's license, social security card, credit card and debit card.

It didn't take long for someone to run errands with his credit card to Lowe's and Dollar General. Then, after a few guesses at his pin number, the thief used his debit card, too.

"He didn't have that much because he had just had a motorcycle accident and was just recuperating, getting back on his feet," Fields said.

A Tulsa Police financial crimes detective said $1,100 has been stolen from Briscoe.

Fields just can't believe that someone could take advantage of her son, almost dying on the side of the road.

"It's just low. I just can't believe anybody would even stoop to that," she said.

Briscoe is still in the hospital recovering.

Police are getting surveillance from another store where Briscoe's cards were used.

They ask anyone with information to call Crime Stoppers at 918-596-COPS.
