The Texas House of Representatives committee report on the Robb Elementary School shooting revealed the accused school shooter exhibited many warning signs in the years, months and days leading up to the school shooting, but he was still able to legally purchase the assault rifle used in the shooting.

The report illustrated many failures by the school and by law enforcement officers leading up to and on the day of the shooting and caused outcry among families of the 21 people killed in May.Private individuals were the only people who knew of the many warning signs he displayed, as he had no criminal history prior to the shooting. The alleged shooter's apparent motive was a "desire for notoriety and fame," according to the report.

Those interviewed by the committee, including family, friends and acquaintances, reported many warning signs that experts say should have raised red flags.
