The case over Khimberly Zavaleta Chuquipa now moves toward juvenile court review while her family presses claims that school officials ignored months of bullying.
LOS ANGELES, Calif. — Los Angeles police arrested a juvenile on suspicion of murder after the Feb. 25 death of 12-year-old Khimberly Zavaleta Chuquipa, a Reseda student whose family says she was hit in the head during a school confrontation on Feb. 17.
The arrest puts a new criminal focus on a case that had already grown into a wider dispute over campus safety, bullying complaints and school oversight at Reseda Charter High School. The Los Angeles County District Attorney’s Office said April 3 that the case remained under investigation. At the same time, Khimberly’s parents are pursuing a separate claim against the Los Angeles Unified School District, arguing that administrators failed to act after repeated warnings about threats and harassment aimed at both Khimberly and her older sister.
According to the family’s account, the confrontation began in a hallway at Reseda Charter on Feb. 17, when Khimberly stepped in as a group of students confronted her sister Sharon Zavaleta, 15. The family says another student struck Khimberly in the head with a metal water bottle. She was taken that day to Valley Presbyterian Hospital, evaluated and released. Over the next few days, relatives said, she complained of severe headaches before her condition sharply worsened. She was then taken to UCLA Mattel Children’s Hospital, where doctors placed her in an induced coma and performed emergency brain surgery to stop a hemorrhage. She died on Feb. 25. “This tragedy should never have happened,” family attorney Robert Glassman said after the family filed its claim against the district.
Police have confirmed the arrest but have released little else. Los Angeles Police Officer Charles Miller said the juvenile was arrested Thursday on suspicion of murder and that no further details would be made public because both the victim and the suspect are minors. Investigators also have not publicly answered several questions that have driven community anger for weeks, including whether surveillance video captured the full encounter, whether other students could face school discipline or criminal scrutiny, and how quickly staff members responded after the fight. The family’s legal filing gives the clearest public account so far. It says Khimberly was trying to protect her sister when she was hit, and it alleges that their mother, Elma Chuquipa Sanchez, had reported earlier bullying incidents to school officials multiple times before the fatal confrontation.
The case has resonated far beyond one hallway fight because it touched existing fears about school violence and whether adults stepped in early enough. On March 4, about 100 students gathered outside Reseda Charter High School, chanting for justice and carrying handmade signs near a memorial for Khimberly. Some students accused administrators of downplaying the seriousness of what happened, while school officials posted a message online saying the campus community was grieving and inviting students to share concerns through a private link. In the family’s March 11 claim, lawyers cited district figures showing that nearly one in three middle school students report bullying or harassment and that more than 6,600 incidents involving fights or physical aggression were reported during the 2023-2024 school year. Those figures were included to argue that the danger was not isolated and that the district should have treated repeated complaints with greater urgency.
The legal path now runs on two tracks. In the criminal matter, prosecutors must decide whether to file a juvenile petition and what offense, if any, will move forward in court. Because the suspect is a minor, any case is likely to proceed largely out of public view. As of Friday, no public court filing had been announced. In the civil matter, the government claim filed March 11 is the formal step required before the family can sue LAUSD for damages. Glassman said the district has 45 days to respond. The filing alleges negligence, negligent supervision, dangerous school conditions and failures to investigate reported bullying or impose effective safety measures. Glassman also said the family has not ruled out separate legal action involving Valley Presbyterian Hospital, though their immediate focus remains the school district and the events that led to Khimberly’s injury.
Even as the case shifted into legal language, the public mourning stayed intensely personal. A viewing was held March 17 as relatives prepared for her funeral the next day, and her mother spoke about a child she said loved to sing and had big plans for the future. “I want her to be remembered as a happy kid,” Sanchez said. “She had so many dreams, and she loved to sing.” Students who organized protests described Khimberly as kind, energetic and protective of her family. One student protester said the school community was furious because “a girl was killed” on school grounds and many felt the response from adults was too careful and too vague. That mix of grief and anger has kept pressure on investigators, the district and elected officials as the case moves into its next phase.
For now, the arrest answers only the question of whether detectives identified a suspect. The next milestones are a decision from prosecutors on any juvenile filing and the district’s response to the family’s March 11 claim, which would come later this month if the standard response period holds.
