Passenger becomes unresponsive during Dallas-to-Los Angeles flight
Walmsey was traveling aboard Southwest Flight 958 from Dallas to Los Angeles on Aug. 7 when he experienced a medical emergency and became unresponsive. The flight was headed to Los Angeles International Airport in California. Law enforcement sources said the nature of the emergency was not immediately known.
The passenger was 22 years old, according to records released by the Los Angeles County Medical Examiner. Officials are investigating the circumstances surrounding his sudden death, but no public determination has been made about what caused him to lose consciousness.
CPR and emergency response efforts continue through landing
People aboard the aircraft attempted to save Walmsey after he became unresponsive. CPR was administered during the flight as the plane continued toward Los Angeles. The response reflected an effort to provide immediate assistance before professional medical teams could reach the aircraft.
Paramedics responded when the flight arrived at Los Angeles International Airport. Despite the onboard CPR and efforts by emergency personnel, Walmsey could not be revived and was pronounced dead at the scene. The available records do not identify how long the emergency lasted or whether the flight was diverted.
Medical examiner defers cause and manner of death
The county medical examiner listed Walmsey’s place of death as the Southwest plane at Los Angeles International Airport. His cause of death was recorded as deferred, meaning officials have not completed the determination and are awaiting additional investigation.
No manner of death has been listed. Authorities have not said whether the death was related to an underlying illness, an acute condition, or another factor. Until the investigation is complete, the available records do not establish a medical explanation.
Airline confirms incident but provides limited details
Southwest Airlines confirmed that a medical incident involving a customer occurred aboard Flight 958 while the aircraft traveled from Dallas to Los Angeles. The airline did not release additional information about the passenger or the emergency.
The company directed further questions to local authorities. That leaves the medical examiner and law enforcement agencies responsible for clarifying the circumstances, including the final cause and manner of death. No additional details about the flight or the passenger were publicly provided in the available records.
Fatal medical emergencies have occurred on other flights
The incident follows other reported cases in which passengers became seriously ill or died during commercial air travel. In January 2025, 53-year-old Barbara Dipoli of Kansas died aboard an Air France flight traveling from Paris to Boston. Authorities said preliminary information pointed to a medical episode during the flight.
In June 2024, 8-year-old Sydney Weston became ill and unresponsive aboard a SkyWest flight before the aircraft diverted to Peoria, Illinois. That same month, a 41-year-old American passenger died after suffering a severe medical emergency aboard a Fiji Airways flight bound for San Francisco. These cases demonstrate the varied medical situations that can arise during commercial flights, although they are separate from the investigation into Walmsey’s death.
