'Officer down! Officer down!' Chilling footage reveals deadly shootout in Sacramento

A court hearing is set for Monday for the man accused of killing a rookie Sacramento police officer in a fierce shootout captured in chilling footage from the bodycam of a fellow officer.

Tara O’Sullivan, 26, was among five officers sent to a domestic-violence call Wednesday when a gunman opened fire from behind a door. Brief footage from the bodycam of her training officer, Daniel Chipp, was released over the weekend. It shows Chipp approaching the home, gun drawn, and knocking on the door.

"Police Department," Chipp calls out. "If you are in here let me know. You’re not in trouble, dude."

Then, chaos erupts as a gunman fires more than a dozen shots. The footage shows the ground as Chipp, ducking, runs for cover.

"You OK? You OK?" can be heard.

"This is a high-powered rifle. Get out here now," Chipp says. "We've got one down. ... Officer down! Officer down!"

Chipp says to "stay down" and then notes that the gunman is "still shooting."

Police sent an armored vehicle to the scene to rescue O'Sullivan, who was pinned by the gunman's shots. Police Chief Daniel Hahn said it took more than 45 minutes for O'Sullivan to be rushed to a hospital. She died of multiple gunshot wounds.

Hahn said any officer who tried to save her would have been killed.

"This was an ambush-style attack on Sacramento police officers," Hahn said. "Under the most dangerous and trying circumstances, our officers performed admirably."

The standoff lasted eight hours, with the gunman shooting from multiple rooms and five officers firing their weapons.

Adel Sambrano Ramos, 45, was charged with murder, attempted murder and related charges. The charges include special circumstances that could result in the death penalty, although Gov. Gavin Newsom has ordered a moratorium on executions in the state.

Police had earlier found two guns in a neighboring home associated with Ramos. Prosecutors say Ramos was armed with two AR-15 style rifles assembled from parts to create assault weapons that are illegal in California.

Nine days before the shootout, a judge issued an arrest warrant for Ramos for failing to appear on a charge of battering a young woman.

Hahn lauded O'Sullivan as a dedicated officer.

"I've never seen her not smiling," Hahn said. "She's always been very enthusiastic and committed to being a police officer."

A memorial service is set for Thursday.
