Ariz. deputies seize fighting dogs
Among those arrested was Mahlon Patrick, 63, whom investigators identified as one of the top dog fighting breeders in the country.
''We have dismantled a group of people at the upper echelon of dog fighting. This man has been involved for decades,'' said John Goodwin, a national Humane Society official, at a news conference.
It was not known whether Patrick had retained an attorney.
Most of the dogs were seized from a home in rural northwest Tucson, authorities said. About two dozen were removed from a mobile home property west of the Tucson Mountains.
Leads in the case were developed after Chicago police stopped a vehicle with several fighting dogs last March, and information eventually led to Tucson. Humane Society officials also provided information concerning the possibility of a dog fighting ring near Tucson.
About 10 of the dogs required medical attention. Authorities seized more than 50 weapons and training materials, as well as a device used to hold female dogs in place for breeding.
