WASHINGTON (CBS/AP) Jared Loughner, the man accused of trying to assassinate Rep. Gabrielle Giffords in a shooting rampage that left six dead, was rejected from the Army in 2008 because he failed a drug test, according to a military official.
The official did not know what type of drug was detected in the screening.
The official spoke Monday on condition of anonymity because privacy laws prevent the military from disclosing such information about an individual's application.
The Army has confirmed publicly that Loughner tried to join the Army in December 2008, but was not allowed to serve.
Loughner, whom neighbors described as a social outcast with wild beliefs steeped in mistrust, is charged with one count of attempted assassination of a member of Congress, two counts of killing an employee of the federal government and two counts of attempting to kill a federal employee. More charges are expected.
Those killed included U.S. District Judge John Roll, 63, and 9-year-old Christina Taylor Green, who was born on Sept. 11, 2001, and was featured in a book called "Faces of Hope" that chronicled one baby from each state born on the day terrorists killed nearly 3,000 people in the U.S.
Others killed were Giffords aide Gabe Zimmerman, 30; Dorothy Morris, 76; Dorwin Stoddard, 76; and Phyllis Schneck, 79.Giffords, 40, remains in intensive care at a Tucson hospital.
