"Law enforcement officials found a purchase receipt for one of the guns used in the assault among Cho's belongings.[SUP]
[111][/SUP] The shooter waited one month after buying a
Walther P22 pistol before he bought a second pistol, a
Glock 19.[SUP]
[1][/SUP] Cho used a 15-round magazine in the Glock and a 10-round magazine in the Walther.[SUP]
[112][/SUP] The serial numbers on the weapons were filed off, but the
ATF National Laboratory was able to reveal them and performed a firearms trace.[SUP]

The sale of firearms by licensed dealers in Virginia is restricted to residents who successfully pass a background check.[SUP]
[113][/SUP] Virginia law also limits purchases of handguns to one every 30 days.[SUP]

Federal law requires a
criminal background check for handgun purchases from licensed firearms dealers, and Virginia checks other databases in addition to the federally mandated
NICS. A
1968 federal law passed in response to the assassinations of
Robert Kennedy and
Martin Luther King, Jr.,[SUP]
[86][/SUP] also prohibits those "adjudicated as a mental defective" from buying guns. This exclusion applied to Cho after a Virginia court declared him to be a danger to himself in late 2005 and sent him for
psychiatric treatment.[SUP]

[4][/SUP] Because of gaps between federal and Virginia state laws, the state did not report Cho's
legal status to the NICS.[SUP]
[4][/SUP] Virginia Governor Timothy Kaine addressed this problem on April 30, 2007, by issuing an executive order intended to close those reporting gaps.[SUP]
[115][/SUP] In August 2007, the Virginia Tech Review Panel report called for a permanent change in the Code of Virginia to clarify and strengthen the state's background check requirements.[SUP]
[1][/SUP] The federal government later passed a law to improve state reporting to the NICS nationwide.[SUP]
