Memo to anyone planning a drug store robbery: don't lock your keys in the getaway vehicle.
Police say John Wilkinson, 24, of Big Spring, Texas, did just that after he allegedly robbed the Stanton Drug Store of Zanax and Hydrocodine with what was later found to be nothing more than a caulking gun.
They say Wilkinson used the caulking gun, wrapped in a dark cloth to make it appear like a gun, to get the drugs.
But as he tried to head back to his vehicle, which was parked and running in front of the drug store, Wilkinson discovered he was locked out, reports the Midland Reporter-Telegram.
Stanton Police Chief Mike Adams says Wilkinson then tried to get away on foot but police didn't wait around, and believing he had a gun, shot him in the top of his shoulder during the short chase.
Wilkinson was treated at hospital before being taken to the Martin County Jail on a charge of armed robbery.
