BRIDGEVILLE, Pennsylvania: A gunman who fired dozens of shots into a fitness center exercise class, killing three women and injuring nine, was a 48-year-old man from suburban Pittsburgh.

A person close to the Allegheny County coroner's office says the gunman was George Sodini who lived in Carnegie, just a few kilometers from the health club. The person wasn't authorized to comment on the gunman's identity and spoke on condition of anonymity.

In a website posted under his name, Sodini wrote rambling messages about his hatred of women and how he was tired of being rejected by them. He ended by writing, "Death Lives!"
