We’re hearing more disturbing news coming out of Pennsylvania after a reclusive gunman walked into a local gym with three guns, killing three women, wounding nine others, then killing himself.

Everyone is trying to understand the motives behind 48-year-old gunman George Sodini of Carnegie, PA, which is just a few miles from the L.A. Fitness Club where his Tuesday rampage took place. What we now know, however, is that Sodini’s run of bad luck with women seems to have fueled his hatred for them.

Sodini made videos of himself in which he talked about his difficulty connecting with women, how he was trying to be more "emotional" for them and how he just doesn’t understand why women don’t like him, and posted the videos on YouTube. In one of the videos, books on how to date women can be seen. "My objective is to be real and to be emotional … because when I’m ten to 20 years older than she is, she has to feel good about this thing," Sodini says in one video.

ABC News reports that Sodini briefly considered halting his shooting, according to his online blog. He wrote that if a particular woman he admired would be his girlfriend, he would "cancel this plan or put [it] on hold, at least for a while." We still don’t know who that woman is.

"At the gym I saw a woman I like. I see her at the park-and-ride sometimes, so she isn’t a stranger. Occationaly [sic] she makes good eye contact and smiles, etc. She is maybe 40ish, and attractive to me," Sodini wrote. "I made brief conversation to her and a younger woman she was with today. To get a friend like her (and for night time action) I would cancel this plan, or put on hold, at least for a while."

Sodini’s website diary even referred to his plan to randomly kill women and himself. He said he hadn’t had sex since 1990. The Philadelphia Enquirer says the often rambling entries showed a man full of hopelessness, one who loathed women, religion, his family, blacks, coworkers, life and himself. Police said Sodini once belonged to a church but stopped attending after an incident in 2006, during which a pastor said he had "overreached" with a woman.

"It’s of no surprise to me that he’s targeting women … the leader of this [exercise] class was about to be a mother," one mental-health expert told MSNBC this morning, adding that perhaps Sodini’s own mother treated him poorly. "It’s this perfect storm of having severe depression, mild rage, he felt like he was being bullied."

Patricia Cowen lived across the street from George Sodini. She learned that he wrote about her daughter, referring to her as "a long haired, hot little hottie with a beautiful bod." The thought that this man lived so close to her family and was watching them was "devastating," she told CBS News.

"It’s just so overwhelming," Cowen said. "Just the idea of somebody like that thinking like that for a young girl. My daughter is a college student, and, you know, just to think if I would lose somebody like that, I don’t know what I would do."

This horrible tragedy happened at a gym, where we go to work out some stress and try to relax. Does this shooting make you question the safety and comfort level at your own gym?

Here’s one video Sodini made, during which he talks about trying to find a woman:
