Members of the Pima County Sheriff's Office have heavy hearts as they put to rest one of their best deputy canines.
The Pima County Sheriff Clarence Dupnik said Deputy Gerald Ahern's partner, Kilo, had to be euthanized Tuesday after an unexpected spinal cord injury.
Dupnik said Kilo was off-duty and chasing a toy in Ahern's backyard when a broken piece of spinal disk paralyzed the back half of his body.
Kilo joined the department in November of 2010 and after 12 weeks of basic training, Ahern and Kilo were certified by the National Canine Association in narcotics detection and patrol.
Dupnik said Ahern and Kilo were one of the most productive narcotics teams in the history of the Pima County Sheriff's Department Canine Unit.
Since February 2011, the pair did 263 drug searches and Kilo found 4,723 pounds of marijuana, 43 pounds of cocaine and more than $1 million in drug money. One of his biggest cases was just two weeks before his death when they searched a tractor-trailer and Kilo alerted Ahern to a wooden crate that had a large safe inside containing more than $300,000 in drug money.
