Gym Gunman, College Killers Used Same Shop

An online weapons dealer who sold guns and accessories to those who carried out massacres at Virginia Tech and Northern Illinois University also sold accessories to a man who killed three women at a Pittsburgh-area health club.

Company president Eric Thompson says TGSCOM Inc. sold a Glock Magloader and a Glock Factory Magazine to George Sodini for $46 in April 2008.

It isn't clear if Sodini used the accessories during his attack on a health club Tuesday. Sodini killed himself after opening fire on an aerobics class.

TGSCOM is based in Green Bay. It also sold guns and accessories to the shooters in the two university shootings.

Seung-Hui Cho killed 32 people at Virginia Tech in 2007. And Steven Kazmierczak killed five students before committing suicide at Northern Illinois University in 2008.

Meanwhile, four of the women wounded in the health club shooting remained hospitalized Friday. Three women were in fair condition, with one to be discharged later Friday, and the fourth was in serious condition.

The aerobics instructor, 26-year-old Mary Primis of Moon Township, has been moved out of intensive care.

Two other women are being treated at UPMC Mercy Hospital. One remained in serious condition Friday, while the other is listed as fair.

CBS station KDKA reports that another community vigil has been planned for this evening while visitation for two of the victims is set to also start today.

On Thursday night, mourners gathered at the City-County Building downtown for a candlelight vigil to remember the victims.

Meanwhile, an expert said Sodini shares a chilling trait with other mass killers: the desire to make their woes understood through multiple deaths.

No indication has surfaced that George Sodini had documented mental problems, but his massacre shares threads with others analyzed by psychiatrists and legal experts, who say the line between lonely and homicidal remains hard to place.

"They're thinking, 'I want everyone to understand and appreciate why I'm doing this,' and the way to do that, in their mind, is to kill other people and not just themselves," New York attorney Carolyn Wolf, whose firm specializes in mental health issues, told The Associated Press in a telephone interview Thursday. "In their mind it sends a broader message."

Sodini kept an online journal in which he detailed planning the attack and posted videos on YouTube discussing his need to work on his emotions in order to attract women.

But what do these Internet remnants of the killer say about his mind?

Top forensic psychiatrist Dr. Michael Welner appeared on "The Early Show" Thursday to discuss what the online entries and videos say about 48-year-old George Sodini's mental condition.

Welner, who's credited with developing "The Depravity Scale," a tool that helps judges and jurors distinguish violent crimes from those motivated by pure evil, has consulted on some of the most notorious crimes in recent history, including the Virginia Tech massacre, the murder of Jon-Benet Ramsey, and the terrorist attacks of September 11, 2001.

Welner told "Early Show" co-anchor Maggie Rodriguez many people he encounters in forensic psychiatry look average or normal.

"They look exactly like you," he said. "You expect (shooters) to be monsters because they're built up, and actually, they're quite ordinary."

As for Sodini, Welner said, it was his ordinariness that was at the heart of his attention-seeking crime.

"Crime doesn't pay ... unless you're a mass shooter, because all of that is getting notoriety."
