Police arrest suspect in Sacramento shooting that killed 6

Dandre Martin, 26, was identified as a "related suspect" in the shooting, which broke out on K Street in downtown Sacramento early Sunday morning just after a fight took place, the Sacramento Police Department said. Martin was arrested on assault and illegal firearm possession charges, police said.

More than 100 shell casings were recovered from the scene, according to police. Investigators believe multiple gunmen are responsible for the shooting and are sifting through hundreds of pieces of evidence, Sacramento Police Chief Kathy Lester said during a press conference Sunday afternoon.

Video posted on Twitter on Sunday showed people running through the street as the apparent sound of rapid gunfire could be heard in the background.
