A 3-year-old boy has died after being left in a hot car in Houston on Thursday, officials said.
The toddler is believed to have wandered out of his house and entered the car in what may have been an attempt to retrieve a toy, Houston Police told NBC affiliate KPRC.
Child-safety locks were somehow engaged and the boy was locked inside for about 30-45 minutes until his family — who'd realized he was missing — found him in the vehicle and called 911, KPRC reported.
The toddler was transported to a local hospital in cardiac arrest but later died, according to the Houston Fire Department.
In a press release about the incident the Houston Fire Department warned residents that "rising summer temperatures can cause an increase risk of heat stroke resulting in brain damage and death from children being left in hot cars."
