Sandy Hook

We still don't know why Adam Lanza killed his mother, then 20 children and six teachers at Sandy Hook Elementary School before turning a gun on himself in December 2012. But we do know more about Lanza's life, what his doctors had to say about him and what his parents did to try to help him.

Texas Matters: After reviewing school district safety audits, the attorney general's office found that 78 Texas school districts were not compliant with the law. The Newtown tragedy is also having an effect in San Antonio school districts, where two students who were making jokes about bomb threats and shootings on their own campuses were arrested.

Texas School Safety Center

[Update: Thursday, Dec. 20] The Texas School Safety Center, located at Texas State University in San Marcos, now says there are only 29 schools not in compliance with the safety audits.

This is down from the 78 total districts who did not meet the Texas Education Code safety requirement -- 38 that did not report, and 40 that were not fully compliant. The center said that slow paperwork is to blame for those schools that are now cleared.
