PHOENIX (AP) -- Maricopa County Sheriff's officials say they're planning a thorough investigation into the deaths of 20 dogs at a pet boarding facility in Gilbert.
The dogs reportedly died over the weekend of apparent heat exhaustion.
Authorities say the air conditioning at the Green Acres Dog Boarding Facility went out after one of the dogs managed to chew through the wall and then an electrical cord.
The facility reportedly was temporarily overseen by a son of U.S. Sen. Jeff Flake of Arizona.
Sheriff's officials say the owners of boarding facility were out of town and arranged for the dogs to be taken care of by Austin Flake and his wife, the owners' daughter.
Authorities say when Flakes discovered the dogs at 5:30 a.m. Friday and tried to save what animals they could.
