An intended rape victim shot and killed her attacker this morning in Cape Girardeau when he broke into her home to rape her a second time, police said.

The 57-year-old woman shot Ronnie W. Preyer, 47, a registered sex offender, in the chest with a shotgun when he broke through her locked basement door.

The woman told police he was the same man who raped her several days earlier. Officials do not intend to seek charges against her.

In the first incident, the woman heard glass breaking in her basement about midnight on Saturday. She went to leave the house, and the man attacked when she opened the front door. He punched her in the face and then forced her into a bedroom, where he raped her, said H. Morley Swingle, prosecuting attorney in Cape Girardeau County.

The victim reported the crime to police, and her landlord repaired the broken window.

She was home alone again Friday about 2:15 a.m. when Preyer broke the same basement window. The victim was awake watching television, when Preyer switched off the electricity to her house.

She tried to call 911, but couldn't because the power was off. She got a shotgun and waited as the man began banging on the basement door. She fired when Preyer came crashing through the door. When Preyer collapsed, the woman escaped and went to a neighbor's home, where she called police. Officers, who arrived within a minute, found a bleeding Preyer stumbling away from the house. He was taken to St. Francis Medical Center, where he died several hours later.

Swingle said the victim identified Preyer as the attacker in both incidents. Preyer, of Jackson, Mo., had wet caulking from the recently repaired basement window on his clothing when he was shot.

"I will not be filing any sort of charge against this 57-year-old woman, who was clearly justified under the law in shooting this intruder in her home," Swingle said.
