The Sacramento Police Department has arrested a 26-year-old man in connection with the shooting Sunday morning that left six people dead and 12 injured. 

Police arrested Dandre Martin and booked him on charges of assault with a firearm and being a prohibited person in possession of a firearm, Sacramento PD Chief Kathy Lester told KCRA 3 on Monday. 

"Right now that's really all we're able to share about him," Lester told the outlet. "As you know, this is a complex investigation, and we're looking for multiple suspects, and so we're currently working to identify what his role was the night of the shooting."

Lester was unable to confirm how many other suspects police are searching for due to the ongoing investigation, KCRA reported. The department's SWAT team served search warrants at three residences and recovered at least one handgun.

In a press release on Sunday, Sacramento PD said the six victims were pronounced dead at the scene. The bodies of the deceased remained at the scene on Sunday as officers investigated the "really complex and complicated scene," ABC 10 reported.

KCRA reported that the local coroner's office identified the victims on Monday morning as: 

• Johntaya Alexander, 21, of Elk Grove
• Melinda Davis, 57
• Sergio Harris, 38, of North Highlands
• Joshua Hoye-Lucchesi, 32, of Salinas
• Yamile Martinez-Andrade, 21, of Selma
• Devazia Turner, 29, of Carmichael

At least three buildings and three cars were also hit by the gunfire on Sunday, Lester told KCRA, adding that there were over 100 expelled shell casings at the scene.
