UVALDE, Texas — (UVALDE, Texas) -- A Robb Elementary School employee triggered an internal alert system less than a minute before a gunman entered the building in Uvalde, Texas, and opened fire, according to the company that makes the alert system.
The alert was initiated using a security app on the employee's mobile phone at 11:32:26 a.m. on May 24, a spokesperson for the company, Raptor Technologies, confirmed to ABC News Friday. That was two minutes after the first 911 call, based on the timeline from law enforcement officials.
The employee pressed a"lockdown" button and a button that warned of an active shooter, according to Raptor Technologies. The system then blasted out emails, text messages and cellphone alarms to other school employees. The security app information, first reported by The New York Times, helps answer initial questions about whether the school had enacted any of its emergency protocols when confronted with a gunman on the property.
