ST. TAMMANY PARISH, LA (WVUE) - A St. Tammany Parish Sheriff's Office K-9 died from an apparent heart attack while he was in his kennel, according to a spokesman.
K-9 Rex was known for his "excellent" tracking skills and helped apprehend a number of criminals over his five-year career. Rex was also used for narcotics detection.
The dog was only six years old. Because he was so young, the sheriff's office sent him to the Louisiana State University School of Veterinary Medicine for a necropsy. It was discovered he had a rare heart condition.
"I am heartbroken. Rex was a great partner who lived to serve and protect the citizens of St. Tammany Parish. He will be missed," said Deputy Henry Moore, the dog's handler.
A paw impression of K-9 Rex was taken and put into a cast for Deputy Moore, as well as an urn of K-9 Rex's ashes.
