On Tuesday, a gunman opened fire in the small Northern California town of Rancho Tehama Reserve, about 130 miles north of Sacramento, killing at least four and wounding many others before being shot dead by police.

The 45-minute shooting spree occurred at multiple locations, including an elementary school. The school had a locked front gate, which the gunman rammed through with his truck. It’s reported that school officials heard the gunshots first and immediately put the campus into lockdown, but the sequence of events is still unclear as a number of scenes are under investigation.

As more details come to light, Rancho Tehama Elementary has received praise for their fast response in what could have been a much deadlier massacre. What can other schools takeaway from this elementary school’s protocol under similar circumstances? And what additional security measures could have been taken? We get the latest from both a reporter and a security expert who have been following the story.
