Go inside the crime scene where officer Tara O’Sullivan was killed

With Tara O’Sullivan lying in a backyard wounded by bullets from a high-powered rifle, her fellow Sacramento police officers needed a rescue plan that wouldn’t result in additional bloodshed.

It was 6:10 p.m. on June 19, and O’Sullivan had arrived with her partner at the Redwood Avenue home in North Sacramento about a half hour earlier to respond to a domestic violence call.

With the front door of the house barricaded and a warrant for assault out on Adel Sambrano Ramos, 45, the officers had asked for additional backup. Three additional officers arrived on site.

Two minutes after O’Sullivan was shot, with gunfire spraying from both sides of the house, officers are heard on police radio traffic requesting a BearCat, the department’s armored vehicle.

The BearCat arrived in 18 minutes, but it would be another 26 minutes before it reached the wounded rookie officer.
