powderman, here is another story with a happy ending, from NRA's Armed Citizen page....
A 35-year-old woman called 911 after a man followed her home from a gas station and forced his way inside through the front door. The woman allegedly ordered the man to leave then retreated to her bedroom. The intruder picked up a knife from the kitchen table and followed her. It was reported that he threatened the woman with the knife and ordered her to take off her clothes. She warned the man that she would shoot him, but he continued to push her to undress. She retrieved a 9 mm handgun from underneath a pillow on her bed and pointed it at the intruder. When he continued toward her, she pulled the trigger. The suspect was fatally wounded.

And one a little closer to me, from same source:
Jill Stucker, 64, was at home watching television around 9:20 p.m. when a 26-year-old man broke in through a window. When Stucker heard the glass shatter, she armed herself with a handgun and proceeded to exit through the back door. As she fled her own home, the intruder followed. When Stucker realized she was being chased, she turned and fired a single shot striking him in the chest. The intruder fled, but later collapsed on a nearby doorstep. He was reportedly hospitalized in critical condition. (Lake City Reporter, Lake City, FL, 10/23/12) -- He was later stabilizied to face charges.
