Citing sources, the TV station reported Wednesday Dr. Lynne Fenton, who treated James Holmes this spring, contacted several members of the university's Behavioral Evaluation and Threat Assessment team almost six weeks before the July 20 massacre at a movie theater, cautioning them Holmes might pose a danger to others.
The BETA team is made up of CU staff members with expertise in assessing and dealing with potential threats on campus, the TV station said, citing the university Web site.
The station's sources said university officials did not brief Aurora police about Fenton's concerns before he allegedly killed 12 people and wounded 58 others at the movie theater.
"Fenton made initial phone calls about engaging the BETA team" in June, sources told KMGH-TV.
However, Holmes was in the process of dropping out of school, so the BETA team "had no control over him," the source said.
A CU spokeswoman said Holmes -- who had no criminal record -- lost access to secure areas of the campus June 12.
Holmes faces 142 charges, including 24 first-degree murder counts.
