Authorities say a gunman accused of killing five students in Illinois and the shooter in killings last year at Virginia Tech used the same gun dealer, UPI reported. Steven Kazmierczak bought two 9 mm Glock magazines and a holster for a Glock handgun Feb. 4 from the Web site of TGSCOM Inc. in Green Bay, Wis., CNN reported Saturday. Kazmierczak, 27, of Champaign, Ill., is accused of shooting 21 people, killing five, Thursday at Northern Illinois University in DeKalb before killing himself. Three people remained in critical condition late Friday. Through its Web site, TGSCOM also sold Seung-Hui Cho a gun used last April in the Virginia Tech shootings, the company confirmed in a statement Friday. Cho killed 32 people on Virginia Tech's campus before killing himself. TGSCOM officials said they are cooperating with police in the investigation into the campus shooting in DeKalb, CNN reported. Police described Kazmierczak as an outstanding student who reported began behaving erratically after he stopped taking prescribed medications. Kazmierczak graduated from NIU in 2006, attended graduate school in 2007 and was a current student at the University of Illinois in Urbana-Champaign.
