Susano “Cooch” Archuleta, a 21-year-old man from Stockton, was killed on November 29, 2025, when a toddler's birthday party turned into chaos at a banquet hall on Lucile Avenue. The celebration had drawn a packed crowd—well over a hundred friends and relatives—people gathering close for the cake-cutting, balloons and music still in the air, when the first cracks of gunfire cut through the room and everything changed in an instant.

As guests scrambled for cover, the shooting spilled through the venue, with rounds fired inside and outside. Investigators later recovered more than 50 shell casings and said the gunfire came from at least five different firearms—evidence that pointed to a coordinated attack but did not automatically mean there were five shooters. Officials described the scene as overwhelming and “horrendous” on officers' body cameras, and they warned the public that processing the evidence and chasing leads could take time.

Family members and local reporting described Archuleta's final moments in human terms rather than headlines: amid the panic, he tried to shield others, moving children and his girlfriend toward a closet for protection as bullets tore through the hall. His brother later said Archuleta was shot in the neck, and accounts place his death at the scene or immediately after the attack as loved ones struggled to understand how a night meant for a child could end with so much bloodshed.

Investigators have said the shooting appeared targeted, and they acknowledged that known gang members were among the partygoers, but they have cautioned that motive has not been confirmed. Some public statements and online claims pushed the idea of gang-related violence, yet authorities have continued to frame the case as an active, evidence-driven investigation—one where the “why” is still being built from ballistics, video, witness accounts, and tips rather than assumptions.

As of mid-December 2025, authorities had not announced arrests tied to Archuleta's death or the banquet hall attack, and they have not publicly identified a named suspect. They have, however, said they are looking for multiple suspects described as wearing dark clothing and face coverings, and they have leaned hard on public help—offering major reward money, including an FBI reward of up to $50,000, alongside other reward offers that together rose into six figures in local reporting. Separate from the case itself, five people were arrested on weapons and gang charges in the aftermath of the shooting, but officials have said no direct connection to the banquet hall killings has been confirmed.
