BRIDGEVILLE — A man who sprayed bullets into a fitness class filled with women he didn't know, killing three and then himself, kept a Web page in which he wrote about years of rejection by women and left behind notes describing his inability to get a girlfriend, police said Wednesday.

George Sodini, who worked in a law firm's finance department, was anti-social, according to neighbors, and his Web page showcased a resume setting forth his credentials as an unhappy loner. It listed his date of death — Aug. 4, 2009 — and his status of "Never married."

On the Web site, the 48-year-old Sodini complained of not having a girlfriend since 1984, not having a date since May 2008 and not having sex for 19 years.

"Women just don't like me. There are 30 million desirable women in the US (my estimate) and I cannot find one," he wrote. The page ended with the words "Death Lives!

On Tuesday, Sodini scoped out the gym twice and then returned at night wearing workout gear and a headband and bringing with him four guns, police said. He entered a "Latin impact" dance aerobics class, placed a duffel bag on the floor, rooted around in the bag, turned off the lights and started shooting, police and witnesses said.

Three women were killed and nine women were wounded before he turned the gun on himself and committed suicide. In all, he fired 36 rounds from three of the guns.

Authorities on Wednesday identified the three women who died as Heidi Overmier, 46, of Carnegie; Elizabeth Gannon, 49, of Pittsburgh; and Jody Billingsley, 38, of Mount Lebanon.

Sodini's 4,610-word Web page, on a domain registered in Sodini's name, appeared to be a nine-month chronology of his plans for the shooting, his decision to delay it and the process that led to the eventual carnage.
