The man who opened fire on women in a Pittsburgh gym bought gun accessories from the same web company that sold arms used in two other mass shootings. George Sodini bought a Glock Magloader and Glock Factory Magazine from TGSCOM Inc. The company also sold guns to Seung-Hui Cho, who shot 32 people at Virginia Tech in 2007, and Steven Kazmierczak, who murdered five students at Northern Illinois University in 2008."This tragedy underscores the need for people to protect themselves and not rely only on police," said the company's president, Eric Thompson, who confirmed the purchases. "There is evil all around and we must be able to handle it."
