A three-year-old boy in Mexico died while his mother was out partying.
The child, Vicente, was found unconscious in a vehicle parked outside a home in Mexicali.
Authorities believe he died of heatstroke after being trapped inside the car for more than 12 hours.
According to reports, his mother returned from a party after midnight, went inside and slept.
She forgot that he was still strapped into his car seat as the temperature rose rapidly the next day.
Emergency services were called to Capellania Avenue in La Rioja Residential at around 1:30 pm after a woman raised the alarm.
When officers arrived, they found a woman carrying Vicente, and claimed he was unresponsive.
Paramedics arrived at the scene where they confirmed there were no signs of life.
Forensic experts later determined that Vicente had suffered severe heatstroke.
Burn marks were found on his hands and feet, which were caused by exposure to hot surfaces and extreme temperatures inside the car.
Cesar Gonzalez Vaca, head of the Forensic Medical Service, said the autopsy found no signs of physical violence.
Investigators believe the boy may have died between 9 and 10 a.m., as the temperature rose above 33 degrees Celsius.
He was described as being of a healthy weight and size for his age.
The boy’s father later claimed on social media that Vicente had been forgotten while his mother was under the influence of alcohol.
Officials have not confirmed these details.
Prosecutors from the Baja California State Attorney General’s Office have begun an investigation into the circumstances surrounding his death.
Locals have called for an investigation into the matter as a possible case of neglect.
This is not the first time that a child has died after being left in a vehicle unattended.
In June, a one-year-old boy died after his mother left him in a scorching hot car while she got fillers in his lips.
Maya Hernandez, 20, reached a plea agreement with prosecutors.
She will spend a maximum of 15 years in prison after the first-degree murder charge was changed to involuntary manslaughter.
Hernandez left her two children in 46 degrees Celsius for more than two hours while she received cosmetic injections.
