Aristides Paulino, 58, who works for the city of Miami, was asleep in the couple's Miami Shores home Friday afternoon after finishing a midnight shift, the Herald reported. Clara Paulino had climbed into the backseat of his marked SUV to find something when the doors somehow closed, and a self-locking mechanism engaged, officials said.
Temperatures reached over 90 degrees Fahrenheit as Paulino spent about four hours stuck inside the SUV until her family discovered her body, police said.
The SUV has a cage that separates the back seat from the front seat and has bars on the windows, and the vehicle's doors lock and can only be opened from the outside, police said.
The case is being investigated by the Miami-Dade Police Department, which investigates all unnatural deaths in Miami Shores.
