Two Gramercy men who in March allegedly robbed another man at gunpoint in the L’Auberge Casino parking garage are now in Parish Prison after security officers detained them when they returned to the casino Saturday.

The victim, who deputies said was drunk at the time of the robbery, approached Terrance T. Johnson, 25, and Kerwin Belvin, 23, on March 15 at the casino and asked to buy crack cocaine, according to an East Baton Rouge Sheriff’s Office report.

Johnson and Belvin agreed to sell the man crack and led him to the casino’s parking garage to complete the transaction, the report says.

But instead of handing over drugs, Johnson pulled out a semiautomatic handgun and demanded the victim’s money, the report says.

The victim told sheriff’s deputies that Johnson and Belvin took off running after getting $100, the report says.

A Sheriff’s Office detective identified Johnson and Belvin by using the casino’s identification scanning program, the report says.

Surveillance footage shows Johnson and Belvin leaving the casino with the victim but doesn’t show the robbery, according to the report.

Security guards detained Johnson and Belvin at the casino when the two showed up there on Saturday and alerted sheriff’s deputies, the report says.

After being detained, both men eventually told deputies they stole money from the victim in the parking garage, the report says, though the two men told deputies they stole different amounts.

Belvin said they stole $10, and Johnson, who initially denied being with the victim, put the amount taken at $50.

Both denied having a gun during the robbery, the report says.

When presented with a photo lineup that included pictures of the two suspects, the victim didn’t recognize either man, the report says.

Deputies booked Johnson and Belvin into Parish Prison on one count each of armed robbery.
