Stockton Police are reexamining their policies for police dogs left in squad cars following the death of a K-9 on Tuesday.
There were safety measures in place, but they all failed.
The Stockton Police Department has begun an internal review of the events in which the K-9 Nitro died from the heat after being left in the back of a patrol car on a 106-degree day.
Officer Joe Silva says Nitro was only in the car 15 minutes. The patrol car's air conditioning had been running but failed
"Seeing exactly what mechanisms didn't work so that we can have something so that we can ensure something like this doesn't happen again," says Silva.
Silva says there was also water in the car, another fan, even a sensor that should have provided an alert when the car got too hot.
"Some of the sensors will sound off the horn of the vehicle so that the dog handler would be able to hear the horn is going off and that would alert the handler to get back to the vehicle."
While the review is underway, the dozen K-9 dogs and their handlers will take extra precautions to protect their dogs from the heat.
