(AP) -- A retired Pima County sheriff's patrol and bomb dog was euthanized after attacking an 83-year-old man. The victim, Alexander Dufour, had an arm amputated after the 10- or 11-year-old Belgian Malinois named "Bronco" got out of his yard and attacked him Tuesday on Tucson's northwest side. The Pima Animal Care Center said the dog was involved in a similar incident in December 2001 while still in the service of the Pima County sheriff's office but while off-duty. Bronco was retired from service in December, and ownership was transferred to his handler. Sheriff's Department officials referred questions about the case to the Tucson Police Department, which has taken over the investigation. Sgt. Carlos Valdez, a police spokesman, would say only that the case has been assigned to the aggravated assault detail. Bronco worked with the Sheriff's Department from January 1998 to December 2004. 2005 The Associated Press. All rights reserved.
