The massacre at a Colorado movie theater has investigators raising questions about the extreme amount of firearms that James Holmes allegedly brought into the theater.
Authorities have confirmed that James Holmes began collecting weapons in May and that all of the weapons were purchased legally.
The 24-year-old graduate student brought four different firearms to the theater.
Law enforcement officers have confirmed that the accused shooter brought two handguns, a shotgun and a semi-automatic rifle to the midnight showing of the new "Batman"movie. He left one handgun in his car and brought the other firearms into the theater.
Authorities said none of the guns are considered assault weapons and are in fact typical weapons, owned by millions of law-abiding U.S. families for common sports shooting, hunting and self-defense.
Holmes reportedly entered the cinema through an exit door of the theater. However, some of those who were shot were actually sitting inside an adjacent theater, where bullets penetrated the walls.
Authorities said the guns used in the shooting were purchased legally at two Gander Mountain stores in two separate towns.
The other guns were purchased at two Bass Pro shops, both in Denver. A signifcant amount of ammunition also was bought.
