Disturbing writings were found on a website attributed to someone named George Sodini, who police now believe is the 48-year-old shooter.
In an entry dated January 6, 2009, the author writes, "I can do this ... God have mercy ... I wish life could be better ... I wish I had answers ... Bye."
Two hours after that entry, he wrote: "I chickened out ... I brought the loaded guns, everything."
Then, this past Sunday, Aug. 2, the man wrote: "Tomorrow is the big day ... Last time I tried this, I chickened out. Let's see how this new approach works out."
Allusions to a shooting begin as far back as November of last year: "Why do this to young girls?" he asks.
He ended by writing, "Death Lives!"
Police are not yet sure who the target of the Aug. 4 shooting was but that the gunman went into the health club planning to shoot several people — firing "multiple" weapons "indiscriminately," according to Allegheny County police Superintendent Charles Moffatt. The gunman shut off the lights without speaking, then unleashed a burst of bullets.
"He walked right into the room where the shootings occurred as if he knew exactly where he was going," Moffatt said.
The violence rocked Collier, a bedroom community of about 5,300 residents near Interstate 79, some eight miles southwest of downtown Pittsburgh.
After shooting the women Tuesday night the gunman turned the gun on himself.
