The shooting occurred Saturday afternoon as dozens of relatives, friends, and children gathered to celebrate.

Witnesses said the atmosphere had been filled with music, laughter, and excitement moments before the violence began. Decorations lined the yard, children played nearby, and families shared food and gifts as the party continued.

According to the Stockton Police Department, multiple gunshots suddenly rang out, sending guests running for cover. Several witnesses said they initially mistook the sounds for fireworks connected to the celebration. Within seconds, however, panic spread as people realized they were under attack.

Authorities confirmed that at least four people lost their lives and ten others were rushed to hospitals throughout the area. Emergency crews responded quickly, treating victims at the scene before transporting the injured for further medical care. Hospital officials stated that several victims remained in critical condition following emergency surgeries and trauma treatment.

Law enforcement officials described the aftermath as one of the most disturbing scenes officers have encountered in recent years. Birthday balloons and wrapped presents were left abandoned among overturned tables, scattered chairs, and evidence markers placed throughout the area. Investigators said family members desperately tried to protect children and help the wounded while waiting for emergency responders to arrive.

Detectives immediately launched a large-scale investigation to determine who carried out the attack and why the gathering was targeted. Officers spent hours collecting shell casings, reviewing surveillance recordings, and interviewing witnesses. Some residents reported seeing a dark-colored vehicle speeding away shortly after the gunfire stopped.

Authorities have not yet confirmed a motive, and no suspects have been publicly identified. Investigators believe multiple individuals may have been involved, though officials stressed that the investigation remains active and ongoing.

Community members gathered nearby following the tragedy to pray, comfort grieving relatives, and honor those killed. Local leaders called the violence heartbreaking and unacceptable, especially at an event centered around children and families.

As Stockton mourns the victims, many residents are left struggling to understand how a celebration meant to create happy memories became the setting for such devastating loss and violence.
