The San Joaquin County Sheriff's Office released new surveillance images of two cars that officials believe were involved in the Stockton mass shooting in November.
Up to $130,000 is being offered for more information that leads to the arrest of those responsible for the shooting on Lucile Avenue in Stockton.
The sheriff's office did not provide further details about the make and model of the vehicles, but the photos appeared to show a white and a silver sedan.
In total, 17 people were shot at a child's birthday party and four people were killed. The victims killed were ages 8, 9, 14 and 21.
Investigators believe it was a targeted attack.

In early December, Sheriff Patrick Withrow said it could be weeks or months before any suspects are identified in the shooting. The only thing authorities will say about the suspects is that they were dressed in all black and their faces were covered.
"We know that there were known gang members at this birthday party, but we do not know whether that was the reason or the motive of this shooting, so we're going to take our time and gather all our information and process it," Withrow said in December.'
Withrow said more than 50 casings were found at the scene, fired from at least five different weapons.
