On November 29, 2025, a festive second birthday celebration at the Monkey Space event hall in Stockton, CA, devolved into one of the city’s most horrific acts of violence. Just before 6 p.m., as approximately 100 guests gathered on Lucile Avenue, multiple masked gunmen in dark clothing opened fire. 

The scene quickly transitioned from laughter to terror, with over 50 shell casings from at least five firearms later recovered. Witnesses described a harrowing environment where parents used their bodies to shield children from the bullets tearing through the walls and doors of the venue.

The aftermath revealed a devastating loss of young potential. Four individuals were killed: Maya Lupian, an 8-year-old student at Aspire APEX Academy; Journey Rose Reotutar Guerrero, 8; Amari Peterson, a 14-year-old student-athlete; and Susano Archuleta, 21, who was hailed as a hero for sacrificing his life to protect others. 

Additionally, 13 survivors faced injuries ranging from grazes to life-threatening trauma, forcing local hospitals to activate mass-casualty protocols. The medical and psychological toll on the survivors, particularly the children who witnessed the massacre, remains a critical concern for the community as they struggle with anxiety and sleep disturbances. 

A multi-agency investigation led by the San Joaquin County Sheriff’s Office, with support from the Stockton Police Department, the FBI, and the ATF, suggests the attack was targeted. Although known gang members were present at the event, a specific motive is still being confirmed. 

Significant progress was made in early 2026 with the identification and recovery of two vehicles of interest: a white Honda Accord and a gray Volkswagen. Sheriff Patrick Withrow has expressed confidence that charges will be filed in the coming months as digital and forensic evidence processing concludes. 

With a $130,000 reward offered for information, Stockton remains focused on healing and demanding accountability for an act that violated the sanctity of a child’s celebration.
