(PHOENIX) -- New emails released Thursday by Pima Community College, where accused Tucson, Arizona shooter Jared Lee Loughner attended, shed light on his behavior before he allegedly killed six people and injured 13 others, including Rep. Gabrielle Giffords, in January.
The emails paint Loughner as a struggling student with emotional problems.
In one, a student complained to a writing teacher that Loughner put a knife on his desk. In another, a teacher said she wanted to remove Loughner from class after repeated problems. The dean demanded the matter get quick attention and was told campus police were looking into Loughner's background.
The emails showed that college officials contacted the Bureau of Alcohol, Tobacco, Firearms and Explosives to find out if Loughner had any guns in his possession but no firearms turned up in their check.
On Sept. 29, 2010, Loughner was suspended from the school and told he couldn't return unless he underwent a mental evaluation.
The college was court-ordered to release 255 pages of emails after a local newspaper, The Arizona Republic, filed a lawsuit, requesting that the emails be made public.
