Overview

• Nicole Stark Carrillo, a 27-year-old anesthesiology resident, collapsed during a Sept. 15 on-call shift, was evaluated in emergency care, rested on a stretcher outside the operating area, and was found unresponsive around 6 a.m. on Sept. 16.
• The Jalisco prosecutor’s office opened a criminal investigation and registered case 47649/2025, stating that histopathological studies are required to establish the precise cause.
• Relatives dispute the hospital’s account, alleging she was left unattended for hours and saying a preliminary autopsy reported asphyxia of indeterminate cause, which they want thoroughly investigated.
• IMSS states she received immediate medical attention, that authorities were notified, and that the institution is collaborating with investigators and offering support to the family.
• The case has intensified concern in the medical community about resident workloads and the safeguards in place during long, exhausting shifts.
