An Internet gun dealer based in Green Bay that sold a weapon to the Virginia Tech shooter last year sold handgun accessories to the man who killed five at Northern Illinois University Thursday.

Eric Thompson says that his Web site, www.thegunsource.com, sold two empty 9 millimeter Glock magazines and a Glock holster to Stephen Kazmierczak on February 4.

The order arrived on Tuesday, just two days before the 27-year-old opened fire in a classroom and killed five before committing suicide.

Thompson says he has no idea whether the shooter was using the holster or magazines he sold. Each magazine can hold 33 bullets. Thompson says his site did not sell Kazmierczak any bullets or guns.

Thompson's site also sold a handgun to the person who killed 32 people on the Virginia Tech campus last year.
