FRUITLAND PARK, Fla. — A Florida delivery driver who died inside an Amazon-branded van in August was killed by carbon monoxide poisoning, according to findings released in November. Investigators subsequently documented a dent in the vehicle’s exhaust pipe and detected rising carbon monoxide levels inside the van while its engine ran. The medical examiner classified her death as accidental, but the findings do not establish when the pipe was damaged or who, if anyone, was responsible for the condition of the vehicle.

The driver, Jaylene Vargas Gonzalez, 31, was found unresponsive on August 10, 2026, near Clark Road in the Fruitland Park area of Lake County. The Lake County Sheriff’s Office disclosed the accidental carbon monoxide finding on November 6, according to WFTV and WESH 2.
What the medical and vehicle examinations found
An autopsy recorded a blood carboxyhemoglobin saturation of 58%, according to WKMG reporting carried by News4JAX. Carboxyhemoglobin forms when carbon monoxide attaches to hemoglobin, reducing the blood’s ability to transport oxygen. The autopsy reportedly found no traumatic injury or natural disease explaining her death.
In an investigative report described by PEOPLE, authorities noted a dent in the van’s exhaust pipe. Investigators restarted the engine and monitored the vehicle’s interior at 10-minute intervals; carbon monoxide readings increased. The vehicle was released to the owner’s towing company after documentation, with a warning that it was unsafe, the report said.
The presence of exhaust-pipe damage and rising interior readings are significant evidence of a hazardous vehicle condition. They do not, on their own, establish what caused the damage, whether it was detectable before the shift, or whether a maintenance failure occurred.
She reported dizziness and a severe headache
Investigative records reviewed by PEOPLE state that Vargas Gonzalez sent a message at approximately 4:20 p.m. describing an ammonia-like smell in the van, dizziness and a severe headache. Investigators also reviewed footage recorded inside the van that showed her handling packages before she appeared to suffer involuntary movements and collapsed.
Carbon monoxide itself has no smell. The odor she described may have come from other exhaust components or another source; published findings do not establish its precise origin. Dizziness and headache, however, are symptoms associated with carbon monoxide exposure, according to the Centers for Disease Control and Prevention.
A neighbor called for a welfare check
A resident, Patrick Miranda, contacted authorities after observing the running Amazon delivery vehicle parked near his driveway for several hours. Deputies responded around 7:22 p.m. and discovered Vargas Gonzalez unresponsive inside the rear of the van. Firefighters and emergency medical personnel responded; she was pronounced dead at a hospital, according to WKMG’s original August coverage and WESH 2.
Miranda told local journalists that one deputy seemed to recoil after opening a door and that responders initially took precautions because they did not know what fumes might be present. The November medical findings clarified the cause of death, which had remained undetermined in the first reports.
What the case means for delivery-vehicle safety
The CDC warns that even a small exhaust leak can allow carbon monoxide to accumulate inside a car or truck and recommends regular exhaust-system inspection. A separate 2021 Occupational Safety and Health Administration fatality record documents another delivery worker who died after a van’s tailpipe became submerged in water and carbon monoxide built up. The earlier case involved a different employer and circumstances; it is included here only as evidence that vehicle-exhaust exposure is a documented occupational hazard.
For drivers who develop headache, dizziness or confusion while a vehicle is running, the CDC advises treating possible carbon monoxide exposure seriously. Move to fresh air and seek emergency assistance; the gas cannot be detected by smell alone.
What remains unanswered
Publicly available findings have not established when the exhaust pipe was dented, how the gas entered the occupied compartment, who maintained or owned the particular vehicle, or whether an earlier warning or inspection could have prevented the death. The medical examiner’s accident ruling describes the manner of death, not a final determination of civil or workplace liability. No finding of negligence should be inferred without further evidence.
Amazon said in an August statement to local outlets that it was deeply saddened and was cooperating with investigators. Its updated response, if any, to the newly disclosed mechanical findings was not independently verified for this report.
