LA Medical Examiner Rules 12-Year-Old Khimberly Zavaleta Chuquipa Died of Natural Causes After School Head Injury Case

 Los Angeles County officials have issued a revised ruling in the death of 12-year-old Khimberly Zavaleta Chuquipa, changing the medical classification of her case to natural causes after previously drawing national attention as a possible criminal matter linked to a school incident involving a head injury.

Khimberly died on February 25 after suffering a catastrophic brain hemorrhage days after an incident at school in which she was reportedly struck in the head by an aluminum water bottle. At the time, the case prompted a police investigation, and a juvenile was later arrested on suspicion of murder as authorities initially examined whether the school incident directly contributed to her condition.

However, the Los Angeles County Medical Examiner has now ruled that her death was caused by a pre-existing medical condition rather than external trauma. Officials determined that Khimberly had a cerebral arteriovenous malformation, commonly known as an AVM, a rare congenital condition involving abnormal and fragile blood vessels in the brain that can rupture unexpectedly.

Medical experts explained that AVMs can remain undetected for years without symptoms and may rupture suddenly, causing life-threatening internal bleeding within minutes. In this case, investigators concluded that the rupture leading to Khimberly’s death was consistent with a natural medical event rather than being directly triggered by the earlier head injury reported at school.

Despite the revised ruling, Khimberly’s family continues to strongly dispute the findings. Their attorneys argue that she was a healthy child before the incident and emphasize that she began experiencing severe headaches shortly after being struck at school. She was initially treated at an emergency room and sent home before her condition rapidly worsened, ultimately leading to her collapse and emergency hospitalization.

Khimberly was later taken to UCLA Children’s Hospital, where she underwent emergency brain surgery after doctors identified significant bleeding. She was placed in an induced coma, but despite intensive medical efforts, she passed away days later, leaving her family and community devastated by the sudden loss.

Her case initially drew widespread attention after surveillance video reportedly showed earlier bullying involving her sister at school, with Khimberly stepping in during the confrontation before the alleged water bottle incident occurred. The sequence of events became central to early legal and public discussions surrounding accountability and school safety.

Following the medical examiner’s ruling, questions now remain regarding the future of any criminal proceedings. The initial arrest made by LAPD in April was based on the assumption of a potential link between the school incident and her death, but the new classification may significantly impact how prosecutors proceed moving forward.

Khimberly’s family remembers her as a joyful and vibrant child who loved music, volleyball, her dogs, and spending time with loved ones. They continue to call for a deeper review of the circumstances surrounding her condition, including both medical and school-related factors, while expressing heartbreak over the loss of a young life they say showed no prior signs of serious illness. Authorities have stated that the case remains subject to review as all medical and investigative findings are considered together in determining any further legal action or closure.
