A barking Rottweiler didn't scare off the intruder at an Anaheim, Calif., home Sunday night, but when the 72-year-old grandmother who lived there started shooting and cursing, that did the trick.

Jan Cooper was home with her 86-year-old World War II veteran husband Bob when the alleged intruder attempted to break in around 12:30 a.m., reports the Associated Press. Cooper got her .357 Magnum revolver and called 911. During the call with the dispatcher, Cooper could be heard saying, “Back up, you son of a *****. Back up! Get out of here! Get the hell out of here! Get your butt out now!” reports CBS Los Angeles. Her pet Rottweiler could be heard barking as the intruder first attempted to break in through the front door and later the sliding glass door located at the back of the house, notes CBS Los Angeles.

As she describes the situation to the 911 dispatcher, reporting on the intruder’s location, Cooper can be heard saying “I’m firing,” followed by a gunshot. The shot narrowly missed the intruder, and he fled the premises and was soon arrested near the residence by police responding to Cooper’s 911 call, reports AP. He was identified as 31-year-old Brandon Alexander Perez, who'd been previously convicted of burglary, as well as narcotics charges, and was staying at a nearby halfway house, reports AP. He has pleaded not guilty to the burglary charge.

According to Orange County Sheriff's Department spokesman Jim Amormino, the intruder was not deterred by the dog barking and Cooper’s action prevented something more serious from happening. Amormino said, “Even though that dog was barking, [Perez] still was desperate to get in. So who knows what may have happened if she didn't fire that round,” notes AP.

Cooper, who was considered a “tomboy” and tried her hand at archery and knife-throwing, has legally owned the gun for 20 years, reports AP. As for the cursing, Cooper said she was shocked the words came from her mouth. “I am a Christian woman and I'm very proud of it and I don't curse, but after I shot, rage took hold and I just blasted away,” Cooper said at a press conference. “And, in fact, afterwards my husband said, 'I've never heard you talk like that!'”

As the Coopers have spent time shooting at gun ranges, Bob said he knew what his wife was capable of and wasn’t surprised she fired the shot, notes AP.
