Weston said Emma, a black lab which has been working at the airport for 2-and-a-half years, passed away on Tuesday afternoon.
She said the dog was left inside the K9 vehicle when the air conditioning malfunction and the car overheated. The dog was found dead in the car around 5:30 p.m.
Weston said the handler last checked on the dog a little after 4 p.m.
Emma was the airport's only bomb sniffing dog.
