Melinda Walker Fights Off Intruders With Guitar Hero Controller

Now THAT'S a guitar hero.

Melinda Walker, of Fort Wayne, Ind. was at home with her 5-year-old grandson Sunday when three men barged in and demanded she give them cash and the TV, WANE reported.

"All I thought of," Walker told the station, "was, 'you're getting away from my grandson.'"

The intruders told her they had a gun, but Walker says she couldn't see one.

"[A Guitar Hero video game controller] was laying on the floor. And I just reached down and picked it up and I told them to get the hell out of my house. 'Get out of my house. Get out of my house!' I just kept smacking one of them."

Walker said she then pushed "the one that wouldn't shut up" down the stairs. Eventually the trio -- who she estimates were between 15 and 21 years old -- fled without taking anything.

The woman says that one time in the past, robbers made off with a flat-screen TV, but she's not going to let that happen again.

"I may not be a strong woman. I may not be a well woman, but you're not going to get my stuff."

Walker isn't the only brave lady to thwart would-be robbers recently. On Monday, 96-year-old grocery store owner Margaretta Wolf came face-to-face with knife-wielding man who demanded cash, and she just said "no."

"I said: 'I'm not opening up that cash register and that's it, I'm not opening it. I said you can have all the Tootsie Rolls you want but I am not opening that cash register,'" Wolf told WAOW-TV. The would-be robber eventually left.

In 2012, 57-year-old Lulu Campbell had just dropped off her grandson when two armed men approached her and demanded money. When one fired a shot at her, Campbell whipped out her own gun and fired back, sparking a shootout that ended in both assailants running away.
