Suspect to appear in court as complex investigation of the Sacramento shooting continues. Here's what we know

One man has been arrested in connection with a shooting in downtown Sacramento, California, that left six people dead and a chaotic crime scene littered with more than 100 shell casings.

Dandrae Martin, who was identified as a "related suspect," is scheduled to appear in court Tuesday after being booked on assault and illegal firearm possession charges, according to police.

Sacramento County District Attorney Anne Marie Schubert noted in a statement posted online that Martin, 26, has not been charged with a homicide. She said she thinks authorities will eventually take more people into custody.
