Sandy Hook Elementary


Educational (School) & Lone Wolf Attacker



On the morning of December 14, 2012, 20-year-old Adam Lanza went to Sandy Hook Elementary School (SHES) in Newtown, Connecticut, where he shot his way into the building with a Bushmaster Model XM15-E2S rifle and continued on a spree of violence that left twenty children and six adults dead and two adults wounded. The shooter then took his own life with a single shot from a Glock 20, 10 mm handgun. From the time the doors of the school were locked at 9:30 a.m. until the time it is believed the shooter killed himself at 9:40:03, fewer than 11 minutes had elapsed. Prior to going to the school, Lanza used a .22 caliber Savage Mark II rifle to shoot and kill his mother in her bed in the home they shared at 36 Yogananda Street, also in Newtown, Connecticut.

Active Intruder Mitigation System (AIMSTM) was developed by Intrusion Technologies following the attack at Sandy Hook Elementary School. The creators of AIMS felt compelled to develop effective solutions for comprehensive protection of school children and caretakers while they are in the learning environment to keep violent intrusion incidents from becoming mass casualty incidents.

Careful study of the circumstances that have occurred in the various active shooter events and violent facility intrusions at educational and other facilities revealed some common themes, and among them, most prevalent, is that from Columbine High School to the Navy Yard shootings, the mass casualties associated with these events can be prevented. AIMSTM incorporates training, hardening of the structure, saferoom technologies, immediate notification systems, and a disorienting agent to provide the necessary comprehensive protection of our most precious assets, our children and their caretakers.

To demonstrate the potential for AIMS in educational facilities, Intrusion Technologies developed the AIMS at Work Series to show how AIMS could have produced a different outcome in certain violent intrusion events. In this document you will find a timeline of the event at Sandy Hook Elementary and how AIMSTM would have provided protection to the occupants.

It is not the intent of the founders of Intrusion Technologies to point fingers of blame in these situations or use tragic situations to their benefit. All experienced public safety providers, the founders believe strongly in using the lessons of history in violent intrusions and attacks to help prevent them in the future. All of our hearts go out to the families of those who lost loved ones in these senseless attacks.

The events of December 14, 2012, and other similar active shooter/violent intrusion events indicate that a systematic rapid response product is effective in mitigating the damage caused by active shooter(s). The AIMS™ product is that type of a system. AIMS™ reacts in milliseconds once activated. It isolates potential victims from the shooter. Provides a facility-wide alarm that forces staff and occupants to react as trained. Law enforcement and other response agencies have the necessary equipment and training to neutralize the attack with the aid of the AIMS. The bottom line is this – AIMS holds the potential to save lives and provide victim-initiated mitigation that will keep our children safe. For additional information please contact:
