OKLAHOMA CITY -- A frustrated man pulled a knife on a clerk at a south-side convenience store, but some "very good detective work" has him under arrest.
Felma Thomas, 50, is now facing criminal charges, after robbing the Q-Max Shamrock on S. Agnew Ave.
Court documents show Thomas tried to purchase several items with a state food stamps card. At first, he entered an incorrect PIN number. The second time he swiped, the card showed insufficient funds.
Thomas told the clerk he must have had the wrong card and walked out the door. He returned a short time later to try again.
For a second time, the card showed "insufficient funds."
That's when court documents say Thomas pulled out a small pocket knife and told the clerk: "Okay, I'm done b*** s****ing, give me the money. Give me the money from the drawer."
Thomas also took money from the clerk and left the store. But it was hardly a clean getaway.
"[The card] left a serial number so we could see exactly who it belonged to and that led us to the suspect's name," said police Master Sgt. Gary Knight. "So the clerk had a digital imprint of it where he tried to run it."
A detective, with the help of Department of Human Services, was able to trace the card to Thomas. His picture appeared to match images captured on a security camera.
Through an online database, detectives could determine Thomas had made several trips to a local metal recycling shop.
"He goes to a metal recycling place very often," Knight said. "We were able to figure out what vehicle he drives there, trace it to his vehicle and get a warrant issued for him."
Thomas is currently in custody on $40,000 bond. He has a criminal history dating back to 1989.
