ST. LOUIS, MO (KPLR) -  - Since the Sandy Hook massacre in 2012, there have been about 75 school shootings.  It's a threat that schools and police officers around the country are taking seriously and preparing for.  The smartphone HERO911 app allows teachers to instantly alert all police officers within 10 miles of their school, that an active shooter is inside of the building.

Teachers scrambling to protect protect children won't have to take the time to speak with a 911 operator and police won't have to wait for a dispatcher to relay information.  This is something that will be available at schools and police departments in our area.

More than two dozen area police departments will be at Wednesday's workshop.

A police lieutenant who responded to the Sandy Hook massacre will also be a part of the workshop.

The event will be held at the Engineer's Club of St. Louis.
