Claudia Gallardo, a 38-year-old mother of three from Stockton, California, was killed on April 11, 2013, after being mauled by a pit bull named Russia while visiting the home of Brian Hrenko to discuss house cleaning services. The attack happened in Hrenko’s front yard; Gallardo sustained massive injuries to her face and neck and was pronounced dead at the scene. Russia had a reported history of aggression, including prior attacks on animals and people in the neighborhood.

Brian Hrenko was arrested and charged with involuntary manslaughter and felony animal offenses. Prosecutors said Hrenko knew of the dog’s vicious tendencies and failed to secure the property or warn visitors; evidence at trial included claims that the backyard fence was not properly maintained and that warning signage was insufficient. A jury convicted Hrenko of involuntary manslaughter and keeping a mischievous animal that killed a person. The pit bull Russia was euthanized in January 2015.

If anyone knew Claudia, her family, or had information about the dog or the property before April 11, 2013, please come forward.
