Police believe the same man robbed the QuikTrip at 36th and Peoria about an hour-and-a-half later.
Officers said a man entered the store at 1:35 a.m., implied he had a gun and demanded money. After getting the cash, the man ran southwest.
A man robbed the QuikTrip at 49th and Harvard at about 4:30 a.m.
In that robbery a man walked up to the clerk and demanded money. After getting cash, he got into a white 4-door car with black rims, which headed northbound on Harvard.
