WASHINGTON (AP) - The four weapons recovered in the deadly shootings in Colorado all were purchased by the suspect in the case from retail gun stores in Colorado in the last two months, according to a federal law enforcement official.
Suspect James Holmes bought one of the four guns -- the first of two Glock pistols -- on May 22 at Gander Mountain in Aurora, according to the official, who spoke on condition of anonymity because the probe into the shootings is ongoing. The other purchases:
--On May 28, six days after purchasing the Glock, Holmes purchased the shotgun used in the shootings from Bass Pro Shops in Denver.
--On June 7, Holmes bought the AR-15 assault rifle rifle used in the attacks at a Gander Mountain store in Thornton, Colo.
--On July 6, Holmes returned to the Bass Pro Shops store in Denver and bought the other Glock pistol.
Holmes had a high capacity ammunition clip in the assault rifle, according to a second federal law enforcement official.
The second official, who also spoke on the condition of anonymity to discuss the ongoing investigation, said Holmes had a drum-style clip in an AR-15 assault rifle used in the attack at a movie theater in Denver suburb Aurora, Colo.
The type of ammunition clip Holmes used in his assault rifle was banned for new production under the old federal assault weapon ban, said Daniel Vice, senior attorney for the Brady Center to Prevent Gun Violence.
When the ban expired in 2004, gun manufacturers flooded the market with the type of high capacity magazines Holmes used Friday, Vice said.
Holmes is also believed to have hurled two gas canisters into the theater before opening fire.
