Stockton, Calif. — What was supposed to be a Saturday evening of cake, balloons, and a swan-shaped bouncy house became one of the deadliest attacks on children in this region’s recent memory. On November 29, 2025, shortly before 6 p.m., gunfire tore through a toddler’s birthday party at Monkey Space, an event hall at 1955 Lucile Avenue in the Sherwood Manor neighborhood of unincorporated San Joaquin County, just outside Stockton’s city limits. Four people were killed. Thirteen others were wounded. Three of the dead were children.
Between roughly 80 and 100 relatives and friends had gathered for a 2-year-old girl’s birthday. The hall had been booked in person by the child’s mother, Patrice Williams. Guests were inside a former children’s theater space that shares a parking lot with other businesses near Thornton Plaza. Decorations were still up. Children were in party clothes. Dinner had not yet fully started.
Williams later told reporters she first thought the noise was balloons popping — balloons she had inflated earlier that day. Within seconds the sound was unmistakable. Investigators would eventually say more than 50 rounds were fired from five firearms. The gunfire began inside the hall and continued outside. Deputies believe more than one shooter may have been involved. The attackers left before the first officers arrived. San Joaquin County Sheriff Patrick Withrow said the first units reached the nearby plaza in about four minutes.
No one has been arrested for the shooting. As of the latest public updates in 2026, the case remains open, the motive unproven, and the perpetrators unidentified.
The dead
The four people killed were identified by families, schools, and authorities in the days after the attack:
- Journey Rose Reotutar Guerrero, 8, a third-grader at Commodore Stockton Skills School.
- Maya Lupian, 8, a third-grader at Aspire APEX Academy, described by her family as a child who loved to draw, sing, and dance, and who had earned a purple belt in karate.
- Amari Peterson, 14, of Modesto, a freshman who played football and basketball. His father, Patrick Peterson, later told the New York Times he did not want to question God, and that losing his son had left him “questioning everything about life.”
- Susano Archuleta, 21, of Stockton, who was shot in the neck and died at the scene, according to his brother, Emmanuel Lopez.
Early sheriff’s statements listed the dead as ages 8, 9, 14, and 21; later identifications settled on two 8-year-olds, the 14-year-old, and the 21-year-old. Injury counts also moved as hospitals finished triage. Initial dispatches spoke of about 10 or 11 wounded. The figure that held in later official and news accounts was 13 injured, at least one of them critically. Among the wounded was Lopez’s 9-year-old daughter, who was shot in the head and survived. Lopez told the Los Angeles Times she escaped through a back door and over a fence.
Williams said her other daughter, a cousin, and three friends were among those hit. Guests and neighbors pressed towels to wounds before paramedics arrived. Area hospitals took multiple gunshot patients in a short window.
What investigators have said
The scene sits outside Stockton city limits, so the San Joaquin County Sheriff’s Office leads the case, with Stockton police, the FBI, the Bureau of Alcohol, Tobacco, Firearms and Explosives, and federal prosecutors assisting. Withrow asked the public for doorbell video, phone footage, and even rumors. A reward for information later grew to about $130,000.
In early December 2025, Withrow said detectives had recovered evidence of at least 50 rounds from five guns, and that the number of firearms did not by itself mean five shooters. He also said known gang members had been among the guests. He was careful not to close the motive: presence of gang members, he said, was not proof the shooting was gang-related, and investigators would not rush that finding. Stockton Mayor Christina Fugazi was less guarded in public remarks, describing the attack as gang-related terrorism. Governor Gavin Newsom’s office called the shooting horrific.
By January 2026, authorities said they had identified two vehicles believed to be connected and were still asking for help. By late February, the Sacramento Bee reported that three months on, no suspect was in custody and no criminal case had been filed for the killings. Two men who had been at the party — Luciano Guerrero, 22, and Billy Lee Williams Jr., 31 — were in custody on unrelated parole matters, not on charges of carrying out the shooting. Wikipedia’s summary of the case, updated into October 2026, still lists the perpetrator as unknown and the motive as under investigation.
Detectives have not publicly confirmed a recovered murder weapon tied to a named suspect, a full account of who was targeted, or whether anyone at the party fired back. Neighbors reported a vehicle leaving quickly. That lead, like others, has not produced an arrest announced to the public.
The hall, the morning after
On Sunday, December 1, relatives returned to the metal door of the banquet hall to collect belongings. Los Angeles Times reporters described a room that the night before had held children in party clothes, balloons, and a swan-shaped bouncy house. The New York Times, reporting from Stockton in early January, noted crime-scene images that did not belong together: a blood-soaked pink unicorn, a small shoe, streaks across the floor, pink and purple and orange balloons, five guns, and more than 50 shell casings.
The venue, Monkey Space, had been listed on Peerspace but was booked in person. It sits in a county pocket north of the city, a detail that mattered for jurisdiction and for how quickly city police could act. The practical difference was small for the families. The party was a Stockton gathering in everything but the map line.
A city that already knew the numbers
Stockton recorded 3,680 violent crimes in 2024, nearly double the statewide rate, a figure cited in background reporting on the shooting. Residents and officials have spent years talking about gangs, under-policed neighborhoods, and a city trying to change its story. Few of those conversations had pictured gunmen walking into a 2-year-old’s birthday.
Fugazi and other local leaders framed the attack as an assault on the whole city, not only on one family. Schools named the children. Aspire confirmed Maya Lupian’s death. Stockton Unified confirmed Journey’s. Counseling was offered to students and staff. Candlelight vigils followed, including one at Weber Point where families of the dead spoke. Archuleta’s mother addressed the crowd. GoFundMe pages appeared for funeral costs.
The grief did not stay inside one week. In January 2026, Stocktonia reported that Emmanuel Lopez — Archuleta’s friend, a guest at the party, and the father of a wounded 9-year-old — was himself shot and killed on December 28, 2025, at an apartment complex in Lodi. Police did not publicly tie that homicide to the banquet-hall attack. For people who had been in the hall, it read as a second blow.
What the invented version gets wrong
Early retellings sometimes placed the party in a residential backyard, with neighbors on a porch and children playing lawn games. That is not what happened. The gathering was inside a rented event hall. The host’s own account — that she mistook the first shots for balloons — is the detail that has held up, not anonymous lines about a “machine” or an unnamed emergency-room nurse. No licensed psychologist named in the early coverage matches the composite expert sometimes dropped into rewrites. Those lines should not be treated as reporting.
The casualty line also needs to stay specific. Four dead. Thirteen injured. Three of the dead were children, ages 8, 8, and 14. “At least ten injured” was an early wire figure, not the later count.
What remains open
Withrow’s office has said the work could take months. That estimate has already been exceeded. The public questions are the same ones deputies listed in the first briefings: who fired, whether the attack was aimed at particular guests, how many shooters there were, and whether anything in the days before the party could have been acted on. Authorities have warned that rumor — including guesses about names and motives — can bury useful tips.
Community response has been the part of the story with a clear record: vigils, school counseling, donation pages, clergy at the scene, and a reward fund. None of that has produced an announced arrest. Nearly a year on, Stockton is still the place where a toddler’s birthday ended with four dead and no one charged for the killings.
Families have asked for the one thing the investigation has not delivered. Williams put it plainly in interviews after the shooting: the people who did this were at a children’s party. They should be in jail.
Official updates, when they come, will come from the San Joaquin County Sheriff’s Office. Names of the wounded have mostly stayed private. The names of the dead have not.
