OKLAHOMA CITY - Oklahoma City police are hoping someone will recognize a man who purchased beer at a liquor store one day before he robbed it.

The suspect was wearing a T-shirt, backpack and baseball cap on the day he bought the beer. Police say he returned the next day, wearing a Dallas Cowboys jersey.

The man pulled out a knife, held it to the liquor store clerk's neck and demanded money. The suspect swiped the cash from the cash register, stuffed it in his pocket and walked out of the store.

Police ask anyone with information about the crime to call Crime Stoppers at (405)235 7300.
