Carlsbad schools briefly locked down after email threat
The threat was quickly investigated and found to not be credible.
The lockdown was in place from 11:12 a.m. to 11:45 a.m., officials said.
Kelly Elementary School, where a man jumped a fence on Oct. 8, 2010 during lunch hour and began firing a gun randomly before being tackled by construction workers, is part of the Carlsbad school district. Two girls were wounded.
Brendan O'Rourke, 41, an unemployed security guard with no connection to the school, has pleaded not guilty by reason of insanity to attempted murder charges. His trial is set to begin next week.
