Missouri Police Dog Dies After Patrol Car's AC Malfunction

K-9 Vader succumbed to heat exhaustion despite emergency protocols; investigation underway

Vader, a 4-year-old police dog, was left in a running patrol car with the AC on.
The air conditioning system malfunctioned, causing the vehicle to overheat.
Emergency heat sensors failed to alert Vader's handler of the rising temperature.
Vader initially showed signs of recovery but later died at a 24-hour clinic.
This is the second heat-related death of a Missouri police dog this year.
