A gun-toting granny clad in pajamas and house shoes robbed an east Fort Worth convenience store early Thursday, telling the clerk, "I am doing this for my grandkids."

The robbery occurred at about 3:45 a.m. at the RaceTrac at 1840 Eastchase Parkway.

According to a police report, the woman entered the store, grabbed an orange drink, then told the clerk she needed two cartons of Newport cigarettes and two cigarillos.

The clerk said that when he turned around after retrieving her items, the woman pulled a handgun from beneath her pajama top and ordered him to open the main register.

She threatened to shoot the clerk if he did not comply, warning that "this gun has a hairline trigger."

The woman fled with the money, cigarettes and cigarillos.

She is described as black with a light complexion, 40 to 50 years old, 5 feet 6 to 5 feet 8 inches tall, and 160 to 190 pounds. Anyone with information about her identity is asked to call the robbery unit at 817-392-4370.
