'And then we heard a shotgun blast'| North Sacramento residents describe police standoff

SACRAMENTO, California — Around 6 p.m. Wednesday, June 19, several officers were on a domestic disturbance call along the 200 block of Redwood Avenue in north Sacramento. Officer Tara O'Sullivan was helping a woman collect her belongings and leave a home when she was shot, Sacramento Police Sgt. Vance Chandler said during a press release.

O'Sullivan, 26, died at UC Davis Medical Center. Adel Sambrano Ramos, the man who allegedly shot and killed O'Sullivan, was taken into custody around  2 a.m. Thursday, police officials confirmed. 

After hearing about the standoff that took place overnight, some have suggested the north Sacramento neighborhood must be dangerous. However, this is not the narrative from people who own homes in the area. 

Jeremy Munoz lives just down the street from the shooting. He said it's a great place to live.

"It's peaceful. We got a bike trail that goes right into Midtown, close to everything. It was weird to look outside and see the bike trail that we're normally on and then cops with shields running across lawns over there," Munoz said. "And then within 30 or 40 minutes, there were cops in heavy armor and ARs. Kinda scared us because this neighborhood is relatively quiet."

Munoz described the tense moments as he heard the shots ring out. Like many neighbors, he at first went closer to see what the commotion was about.

"It almost sounded like an attack gun, a roofing, like someone putting roofing up. But it wasn't consistent like a roofer," Munoz said. "So we thought, 'That's a 9 millimeter.' And then we heard a shotgun blast, and then we heard the fully automatic AR [go] off. That's when we decided to walk back to our houses cause we didn't know what was going on." 

Munoz said he saw more and more reinforcements arrive at the scene. He said this is when it got especially tense.

"They started pushing everybody up, back to our corner and they had police tape," Munoz explained. "And before you know it, by about seven, eight o'clock, we were told to go back into our homes. We had armed police walking up and down this street, too. The end of Fernley was blocked off over by Arden and the Garden Highway. So it was like a small, of what we could see, martial law would be like in our little area here. Very frightening."

Gunfire could be heard all over the neighborhood forcing many to evacuate. 

Beth O'Neill and her two dogs live off of El Camino Avenue. A bullet went through the back of her house, blew through a wall and left a noticeable hole in her closet door. 

"I was just sitting in my house and I heard something like fireworks. Pop, pop, pop," O'Neill said. "I grabbed my dogs and called 911." 

While on the phone with dispatchers she saw someone climb on the roof of her back garage. It's unclear if it was the suspected shooter or police.

"He was just laying down with his gun. A couple of times ready to shoot and one time he did shoot," O'Neill said. 

Moments later, law enforcement knocked on her door and told her to evacuate.

The Twin Rivers Unified School District Police Department opened Noralto Elementary School Wednesday night for residents who were evacuated from their homes. The Sacramento Police Department lifted the evacuation order Thursday evening. Residents were able to reenter their homes, but the police department advised them to stay inside while investigators continued processing the scene.
