( CNN ) -- Before Jared Lee Loughner allegedly opened fire on an Arizona congresswoman , police at an area college he had previously attended were put on alert to keep him off campus , according to e-mails obtained Monday by CNN . The e-mails , dated December 23 and December 28 , show that campus police at Pima Community College were distributing photos of Loughner to staffers and night watchmen , adding patrols in an area of the campus they believed Loughner had visited and searching for videos he 'd posted online . The Monday release of the e-mails came a day after an attorney for the college defended it in a CNN interview for not alerting outside law enforcement about Loughner before the January 8 shooting spree . The attack killed six people and injured 13 others , including U.S. Representative Gabrielle Giffords , R-Arizona , at a Tucson supermarket . Loughner did not have a record of criminal violence before the shootings . `` We do n't report people simply because their behavior is odd and strange , '' the attorney , Alice Callison , said . `` He had made no specific threats against anyone here at the college or anyone else that we were aware of . '' However , the e-mails obtained by CNN through the Arizona Open Records Act show that , before the shootings , Pima officials considered Loughner enough of a threat to bolster security in case he tried to revisit the campus . In October 2010 , Loughner was suspended from Pima and told he could not return without undergoing a mental health evaluation to ensure he was not a danger to fellow students and faculty . Loughner 's suspension occurred after he was reported five times to campus authorities for classroom outbursts . College authorities put out the alert after learning that Loughner may have revisited Pima after his suspension , video-recorded part of the campus and posted the recording online . `` In regards to Jared Loughner , '' wrote college Police Commander Manny A. Amado on December 28 , `` I will have a photo of Jared copied and given to the swing shift crew and have them conduct more frequent checks of the Northwest Campus , to include the night roving CSO . I will also have a copy given to the facilities crew . '' Five days earlier , college police Sgt . Dan Simmons alerted others to a rambling text video Loughner had posted on YouTube . It was not the video containing footage of the campus . `` Haywood happened to find this on You Tube , '' Simmons wrote . `` More drivel from Jared Loughner . Doubt there is anything to it . '' In another e-mail , a college official asked Amado if Loughner had contacted the school to set up an appointment and if `` the facilities guys '' have a photography to identify Loughner if he visited the campus after hours . Callison said it is campus policy not to report students without criminal histories to outside law enforcement . That policy , she said , has not changed since the January 8 shootings . `` We had a process in place , '' Callison said , `` and we dealt with this student in a reasonable fashion based on what we knew at the time . ''
Arizona college police kept eye out for Loughner after suspension . Alleged shooter of Giffords , others , kicked off college campus in October . Campus authorities did not alert outside law enforcement before shootings .
