Police are looking for suspects.

“We are asking the public to help us identify the suspects in this incident and provide any information that can help us [find those responsible],” Sacramento Police Chief Kathy Lester told reporters.

According to Lester, the shooting occurred around 2 a.m. Pacific time near the Golden 1 Center arena, where the Sacramento Kings basketball team plays.

In a statement, the police said that “at least” one firearm was seized at the scene and 12 victims with injuries of varying severity were found.

Several blocks were cordoned off, and evidence was marked. The police did not give details about the age and identity of the victims.

Family members were outside the police lines waiting for news about loved ones.

Among them was Pamela Harris, who said that her daughter called her at 2:15 a.m. and reported that her 38-year-old son Sergio had been shot outside a nightclub.

“She said he was dead. I just passed out,” Harris said. She said she was still waiting for official confirmation from the police, adding: “I can’t leave here until I know what’s going on. I’m not going anywhere. It’s like a dream.”

Public activist Berry Accius, who is engaged in the prevention of acts of violence with the use of firearms, said that he rushed to the scene shortly after the shooting.

“The first thing I saw was a young woman stained with her own blood and the blood of other people. She just spoke on the phone and informed about the death of her sister,” he said.

The shooting took place a few blocks from the State Capitol building: in an area recently converted into an entertainment center.

“The number of dead and wounded is difficult to establish. We are waiting for more information about what exactly happened,” Mayor Darrell Steinberg wrote on Twitter. “The increase in gun violence is a scourge of our city, state and (the) country, and I support all actions to reduce it,” the mayor emphasizes.

The incident occurred a little more than a month after a man shot three of his children and a fourth person in Sacramento before taking his own life.
