Police said the arrest came more than six weeks after Khimberly Zavaleta suffered fatal head injuries following a campus confrontation at Reseda Charter High School.
LOS ANGELES, Calif. — Los Angeles police arrested a juvenile Thursday on suspicion of murder in the death of 12-year-old Khimberly Zavaleta Chuquipa, a Reseda student whose family says she was struck in the head with a metal water bottle during a school confrontation on Feb. 17.
The arrest moves the case from a broad homicide investigation into a juvenile criminal matter, but it does not settle the larger questions around what happened on campus and whether school officials missed earlier warnings. Khimberly died Feb. 25 after days in a coma and emergency brain surgery, according to her family and earlier local reporting. Since then, relatives have filed a legal claim against the Los Angeles Unified School District, students have staged protests outside the school and police have released only limited details about the suspect and the evidence.
The known timeline starts on Feb. 17 at Reseda Charter High School, which serves middle school grades on the same campus. Khimberly’s family has said she stepped in when her older sister, Sharon, was being bullied by a group of students in a school hallway. In that confrontation, the family says, another student threw a metal water bottle that struck Khimberly in the head. At first, the case did not unfold in public as a homicide. The girl’s relatives said she developed serious symptoms in the days that followed, including severe headaches, and was later rushed back to the hospital after suffering a brain bleed. Doctors at UCLA Mattel Children’s Hospital performed emergency surgery, but she died early on Feb. 25 after several days in a medically induced coma. By Feb. 27, police had opened a homicide investigation. On April 2, the LAPD said a minor had been arrested on suspicion of murder. Authorities have not disclosed the minor’s age or gender, and juvenile proceedings, if they follow, are likely to remain largely closed to the public.
Police have released only a narrow account of the arrest, leaving the strongest public narrative to family members, their lawyers and local witnesses. The LAPD has confirmed the arrest and the murder suspicion, but officers have not publicly said whether the injury came from a single blow, whether surveillance video captured the full encounter or whether any other students could face consequences. Khimberly’s family has been more direct. At a March 11 news conference, their attorney, Robert Glassman, said the sixth grader tried to protect her sister when adults on campus did not step in. He said the girl suffered a traumatic brain injury and later died from the damage. Her mother, Elma Chuquipa Sanchez, said the loss left the family shattered. LAUSD has not commented on the family claim itself, citing pending litigation, but the district said earlier it was deeply saddened by the student’s death, was cooperating with law enforcement and was offering counseling and other support on campus. That response has done little to calm critics who say the district has spoken in careful general terms while avoiding the core dispute over whether repeated bullying complaints were ignored.
The case drew wider attention because it quickly became about more than one violent moment in a hallway. Khimberly’s parents say they had reported bullying involving both daughters before the fatal confrontation. In their legal claim against LAUSD, they argue school officials failed to investigate earlier incidents, provide enough supervision or put safety steps in place. Their lawyers also said another student had been attacked in the weeks before Feb. 17 by the same group named in their claim. Those allegations have not been tested in court, and the district has not answered them point by point in public. Even so, they changed the story from a single school fight into a broader argument about campus safety, discipline and whether adults acted early enough. Students amplified that point in the days after Khimberly’s death. Roughly 100 gathered outside Reseda Charter on March 4, according to local reporting, holding signs, chanting for justice and accusing administrators of downplaying what happened. Some said fights had become common at the school and that the campus response often felt too slow or too limited. Those complaints remain allegations, but they have shaped the public pressure around the case.
The legal path ahead is now split in two. In the criminal case, the arrest on suspicion of murder means prosecutors and juvenile authorities will review the evidence and decide what petition or charge, if any, should be filed. Because the suspect is a minor, many next steps may happen in juvenile court, where records and hearings are often restricted. Police also have not said whether the case could end with a lesser filing tied to involuntary conduct, assault or another offense. In the civil track, the family’s government claim against LAUSD is the first formal step toward a lawsuit seeking damages. That claim accuses the district of failing to protect Khimberly after earlier reports of bullying. If the district rejects the claim or does not resolve it, the family could move into full civil litigation. The two tracks will likely develop on different clocks. A juvenile case may turn on confidential filings and court review, while the civil side could bring broader public demands for school records, staff actions and internal safety procedures. For now, neither track has produced a public accounting detailed enough to answer every question raised by Khimberly’s death.
Outside the legal language, the story has stayed intensely personal. Friends described Khimberly as energetic, kind and quick to brighten a room. One student who helped organize a protest said she was always smiling and gave energy to the people around her. During later memorial events, her mother said she wanted her daughter remembered as a happy child who loved to sing and had dreamed of becoming a doctor. A viewing was held March 17 as relatives prepared for her funeral the next day. The mourning unfolded in public because the family chose not to let the case fade into school paperwork and court procedure. Their appearances, along with student protests and local coverage, kept pressure on police as the homicide investigation continued. Thursday’s arrest answered one immediate question by confirming that detectives had identified a suspect. It did not answer the painful ones that still matter most to the family: who saw the confrontation unfold, who tried to stop it, whether earlier warning signs were missed and why a schoolday argument ended with a 12-year-old girl’s death.
As of Thursday night, the arrest had shifted the case into juvenile justice, but no public court filing had been announced and police had not released further details about the suspect. The next milestone is likely to be a prosecutor’s decision on a juvenile petition or a first court appearance, if one is disclosed.
