Detectives are still going through a huge amount of evidence collected after Sunday's deadly shooting.
Dozens of shell casings are among the pieces located on scene - police say those shell casings have been submitted to a national database for what they call "evidentiary review." Investigators have also received nearly 200 videos and pictures submitted by the public, and ask that anyone with such material submit it for the investigation. Sacramento Mayor Darrell Steinberg questioned why the primary shooting suspects, brothers Smiley and Dandrae Martin, were back on the streets following history of violent charges on their records - “Those questions need to be answered and they will be answered over the days ahead,” Steinberg said. According to official reports gathered so far, police said at least two gangs were involved, but have declined to provide more details or name the gangs involved or the affiliation of any suspects.
People can also call police dispatch or Crime Stoppers and remain anonymous - there is a QR code set up on the Sacramento Police Department Community Evidence Portal to make the process easy.
