Police said 14 dogs died Friday after air conditioning failed in the truck they were housed in for a dog show in northern Indiana.

St. Joseph County police Lt. William Redman said the dogs were discovered about 6:20 p.m. outside a hotel in Roseland, just north of South Bend. He said the truck was equipped with air conditioning in the cargo area but that an electrical circuit breaker cut the power. Redman said police do not know what triggered the circuit breaker.

The high was 86 degrees in South Bend on Friday.

Redman said the truck belonged to Lakesyde Kennels and Handling of Wellington, Ohio.

The Humane Society of South Bend is investigating the deaths.
