CHULA VISTA, Calif. — The Chula Vista Police Department wants to make sure local churches are prepared in the event of an active shooter situation. 

On Monday night, the department held a forum in the wake of the deadly Poway synagogue shooting last month.  

The forum included strategies strategies for responding to an "active-shooter incident” or other mass-threat event. 

The two-hour session was designed to help employers and administrators of large gathering places, including houses of worship, identify potential threat indicators and how to respond to them; prepare meeting spaces to reduce potential threats; and effectively react to a shooting or other immediate critical threat.

Police created a PowerPoint presentation covering the history of mass casualty incidents and active shooters, and provided tips on survival.  

Chula Vista police Lt. Dan Peak said the department wanted to address the community’s concerns and advise the public on how to respond if faced with an active-shooter or mass-threat incident.
