Iowa police dog dies after being left in Des Moines patrol car

Officials in Iowa are investigating the cause behind the death of a police dog that was left in a patrol car on Wednesday.

The Labrador retriever, named Harley, was a 7-year veteran of the Des Moines Police Department, NBC station WHO reported.

Officials were unsure whether the car's air conditioning was on, if any windows were rolled down or how long the yellow lab was in the car, The Des Moines Register reported. Police say Harley was paired with Officer Brian Mathis on the department's vice and narcotics unit.

"What we know is that when he came back to the car, his partner of seven years had died," Des Moines Police Sgt. Chris Scott told the Register.

Officials said Mathis had no history of handling the dog poorly, according to the Register, and Des Moines police have eight other K-9s.

told CBS station KCCI “There is nobody that could be more upset and traumatized by this than Officer Mathis,” Scott told WHO.

Des Moines' recorded high temperature on Wednesday was 95 degrees Fahrenheit, according to The Weather Channel.

The Police Department's public information office did not immediately respond to a voice mail Friday afternoon.
