A grandmother armed with a gun proved effective when impeding a residential burglary.

Three people have been arrested after Elaine Stiehl, 78, interrupted their plans. The gun-toting woman prepared to nap around 3 p.m. last Friday when she heard a noise coming from within her home on Mount Carmel Road in Coweta County, Georgia, according to deputies.

After hearing noises, Stiehl loaded her gun, opened the bedroom door, and saw two men standing in her hallway according to the report.

Officials said the thieves were in the process of stealing furs and tools from the home, but after seeing Stiehl’s gun, the men ran out of the residence and fled in a waiting getaway car.

“I don’t know why they selected that house, but they picked the wrong one,” Colonel James Yarbrough from the Coweta County Sheriff’s Office said.

“Neighbors were able to give us a description of the vehicle, we pulled it over and took the subjects into custody,” Yarbrough said.

The suspects and the getaway driver were booked into jail for burglary. The type of firearm used by Steihl was not disclosed.
