TULSA, Oklahoma - A woman fires a gun into the floor during a robbery of a McDonalds restaurant in east Tulsa Sunday evening.

Tulsa Police say they believe she is the same woman who robbed a Fiesta Mart at 15th and Harvard and attempted to rob another Fiesta Mart at 11th and Pittsburg after the McDonalds robberies.

Police say the woman walked into the McDonalds just before 9:30 p.m. near 21st and Sheridan.

Witnesses tell officers she walked up to the counter, demanded money and at the same time pulled out a handgun and fired a shot into the ground.

After getting the cash, she ran out the door.

A short time later, police believe the same woman in the McDonalds' robbery but wearing different clothing attempted to rob one Fiesta Mart, and then held up a second Fiesta Mart.

In all incidents, no one was injured.

The woman is described as 5-foot-4 inches tall and heavy build.

In the two Fiesta Mart robberies, the suspect wore an orange shirt, orange pants, orange mask and white gloves. The orange mask and orange shirt were recovered by police near the intersection of 16th and Louisville.
