UPDATES: What we know about the Sacramento shooting

SACRAMENTO, Calif. — Police are searching for at least one suspect in connection with a mass shooting early Sunday in downtown Sacramento that claimed six lives and left 12 other people injured.Gov. Gavin Newsom called the shooting “yet another horrendous act of gun violence” and said his administration was working with local and state law enforcement “as we monitor the situation.”

“What we do know at this point is that another mass casualty shooting has occurred, leaving families with lost loved ones, multiple individuals injured and a community in grief,” he said. “The scourge of gun violence continues to be a crisis in our country, and we must resolve to bring an end to this carnage.”

Gunfire breaks out after 2 a.m. What we know.

Sacramento Police Chief Kathy Lester said at a news conference that police were patrolling the area at about 2 a.m. when they heard gunfire. When they arrived at the scene, they found a large crowd gathered on the street.

“Officers began lifesaving measures to multiple victims on scene,” police said. “Despite these efforts, six victims were pronounced deceased at the scene.”

Another 12 people had varying degrees of injuries, police said in an update after earlier saying 10 people were hurt. No information was given on their conditions.

Four of the shooting victims were taken to UC Davis Medical Center and one to Sutter hospital, KCRA 3 has confirmed.

Authorities don’t know whether one or more suspects were involved and are asking for the public’s help in identifying who is responsible. Lester did not give specifics on the type of gun or guns used.

At least one gun was recovered from the scene, police said.

Forty evidence markers could be seen on the street on Sunday and investigators seemed to be focused on an area outside of the Sharif Fine Jewelry store.

In video shared with KCRA 3, more than 70 gunshots could be heard as people ran to safety.

Police ask for the public to share information about the shooting.

Video posted on social media showed people running through the street as the sound of rapid gunfire could be heard in the background. Video showed multiple ambulances had been sent to the scene.

This is “a very complex and complicated scene,” Lester said. She issued a plea to the public, asking for witnesses or anyone with recordings of the incident to contact police. They have also created a QR code for people to share related video.

The Sacramento Police Department said 9th Street to 13th Street is closed between L Street and J Street. Zach Eaton, a police spokesperson, said it was “a very complex scene” and the area will be shut down throughout the day.

Witnesses describe the shooting. Family members wait for news on their loved ones.

Berry Accius, a community activist, said he came to the scene shortly after the shooting happened.

“The first thing I saw was like victims. I saw a young girl with a whole bunch of blood in her body, a girl taking off glass from her, a young girl screaming saying, ‘They killed my sister.’ A mother running up, ‘Where’s my son, has my son been shot?’“ he said.

He told KCRA 3 that he did not believe that a fight seen in video on social media was the spark for the shooting. Instead, he believed that “this was something separate” and that gun violence has become “a citywide issue.”

Other family members of possible victims were gathering out at the scene Sunday morning and many mentioned London, a nightclub at 1009 10th Street, as being connected to the shooting location.

But the nightclub said the shooting didn’t happen inside or outside the club.

Dezaray Johnson told KCRA 3 she was shooting pool with her cousin last night “and now he’s gone.”

Pamela Harris was hoping for information about her 38-year-old son, Sergio, and was frustrated that police had not shared details.

“I just think it’s a damn shame that the Sacramento Police Department hasn’t confirmed anything to any of the families,” she said. “I’m not standing out here to be nosy. I want some answers.”

She later got confirmation that her son, father of three, had been killed.

“My son was a very vivacious young man,” Harris said. “For this to happen is crazy. I don’t know what to do. I don’t even feel like this is real. I feel like this is a dream.”

Sacramento police said they would open City Hall as an information center for families.

Meanwhile, pop performers Aly & AJ said their bus was caught in the crossfire of the shooting but they were OK. The duo had performed at the Crest Theatre nearby on Saturday.

Public officials respond to the shooting.

Sacramento Mayor Darrell Steinberg tweeted that “words can’t express my shock & sadness this morning” and called gun violence “the scourge of our city, state and nation.”

He spoke alongside other city leaders later Sunday morning and said that “this morning our city has a broken heart.”

“This is a senseless and unacceptable tragedy and I emphasize the word unacceptable,” he said. “Thoughts and prayers of course are appropriate for the victims and their families and the people who are fighting for their lives in the hospital. But thoughts and prayers are not nearly enough. We must do more, as a city, as a state and as a nation. This senseless epidemic of gun violence must be addressed.”

He called gun violence “a sickness.”

City Council member Katie Valenzuela, who represents the area where the shooting happened, talked about getting a call “that no elected official wants to get.” She said she was heartbroken and outraged.

“Our community deserves better than this,” she said. “I know this is a national epidemic. This is not unique to Sacramento but we can stop it here. We can stop it here. I believe that we have the tools to do this. … Enough is enough. I will travel anywhere I need to travel and I will talk to whoever I need to talk to to get these guns off these streets and give our youth what we need so they can be successful and they don’t get shot down on K Street when they’re out trying to have a good time.” See more of her reaction in the video below.
