The gunman who killed three women in a shooting spree at a Pittsburgh-area gym said in videos he posted on the Internet that he routinely hid his feelings, struggled to "emotionally connect" with people and read books on how to date young women.

The two undated videos, apparently recorded by 48-year-old George Sodini, surfaced on Starcasm.net after the Aug. 4 massacre. Police say Sodini was a misogynist who opened fire on a Latin dance aerobics class at the L.A. Fitness Club in Collier Township, Pa., killing three women and injuring nine others before committing suicide.

In one of the clips, he is seen touring his suburban Pittsburgh home in Scott Township, Pa., starting outside and moving inside the two-bedroom brick house. In the other, Sodini recorded himself standing in a doorway talking about hiding his emotions and trying to "emotionally connect" with people.

During the tour, he pointed out his computers, living space and his basement, where he highlighted his handiwork, hanging paneling and a suspended ceiling. Sodini noted that a sofa and chair in his living room matched and said, "Women will really be impressed."

He also focused on reading material on a table that included a book titled "Date Young Women" and a paper with "Office Politics" printed on the front.

Moving through the home, he talked about a newly purchased dining room set, and he showed his bedroom, which included a bed, computer and a dresser.

"It looks pretty clean," he said. "I'm sure she'll be impressed."

Sodini spoke to the camera in the other video about hiding his feelings. He said he had 15 years left and his goal was to "be real and be emotional" and learn to "emotionally connect with people."

He also talked about relationships with younger women — 10 to 20 years younger — saying a woman in that scenario "has to feel good about this thing."

Sodini's blog, which also surfaced after his shooting spree, revealed he felt ignored by women and had an "exit plan" to avenge his rage.

"He just had a lot of hatred in him and (was) hell-bent on committing this act, and no one was going to stop him," Allegheny County Police Superintendent Charles Moffatt said Wednesday.

Sodini went to the sprawling gym on Tuesday night, turned out the lights on the women's "Latin impact" dance-aerobics class, and opened fire with three guns, spraying dozens of bullets before killing himself.

He did not have a relationship with any of his victims, according to police.

In his Web diary, Sodini wrote of planning the attack since at least November and said he tried to carry it out when the same weekly aerobics class met Jan. 6. But he "chickened out," he wrote.

His anger stemmed from unfulfilled desire: The women at his gym "look so beautiful as to not be human," he wrote. He complained that women "don't even give me a second look ANYWHERE" -- even though he was tan and fit and claimed to dress well and smell nice.

He listed his status as "Never married." In a chilling addition, he recorded the date of his death as Aug. 4, 2009.

Sodini did not have a criminal record, and he bought his guns legally, police said.

His 4,610-word Web diary appeared to be a nine-month chronology of his plans to end his misery with a shocking act of carnage at his gym. He couldn't understand why women ignored him, despite his best efforts to look nice. He wrote that he hadn't had a girlfriend since 1984 and hadn't slept with a woman in 19 years.

"Women just don't like me. There are 30 million desirable women in the US (my estimate) and I cannot find one. Not one of them finds me attractive," the 48-year-old computer programmer lamented.

It was unclear when the Web diary was posted and whether it had been updated online repeatedly since November or posted in its entirety recently.

The health club violence rocked the town of about 5,300 people just outside Pittsburgh.

Killed were Heidi Overmier, 46, a sales manager at an amusement park; Jody Billingsley, 37, who worked for a medical-supply company; and Elizabeth Gannon, 49, an X-ray technician at Allegheny General Hospital.

"She can't be gone," said Gannon's next-door neighbor and close friend, Carl Rady, who knew her for 35 years and said she loved to work out and pamper her dog. "It can't happen that way."

Six patients remained hospitalized, including the aerobics instructor, Mary Primis, 26, who was listed in fair condition. Primis is pregnant but said doctors told her the baby is fine.

Sodini's family issued a brief statement: "Our hearts and prayers are with the victims and their families and we pray for the full recovery of the survivors."

Sodini graduated in 1992 from the University of Pittsburgh with a degree in computer science and had worked as a systems analyst at a Pittsburgh law firm since 1999.

A neighbor, Connie Fontanesi, said Sodini was so anti-social that "we really didn't learn anything personal about him."
