Police have arrested one suspect in connection with a shooting in the centre of Sacramento, California’s capital, on Sunday, that left six dead.
Dandre Martin, 26, has been charged with assault and illegal firearm possession, police said on Monday.
Multiple people are believed to have opened fire in the busy downtown area, close to the state Capitol building.
Officials have identified the three men and three women killed in this year’s worst US mass shooting so far.
Three of the victims were men: Sergio Harris, 38, De’Vazia Turner, 29, and Joshua Hoye-Lucchesi, 32.
Three women were also shot dead: Johntaya Alexander, 21, Melinda Davis, 57, and Yamile Martinez-Andrade, 21.
An additional twelve people were wounded in the shooting and taken to local hospitals. By Monday, seven had been discharged.
The violence was “unprecedented” for the city, its police chief said.
Police have executed several search warrants as of Monday. At least one handgun, now understood to be stolen, was recovered.
