Houston – Nearly six months after at least two dogs fatally mauled Christina Bell in southeast Houston, homicide investigators have turned the case over to Harris County prosecutors. City authorities initially responded to the attack by vicious dogs last January by issuing 12 misdemeanor citations to Tiara D. Thomas, 26, for allowing unvaccinated and unlicensed pit bull mixes to run loose. Animal control and Houston Police Department officials confirm that at least one of the dogs attacked Bell, a 43-year-old often homeless woman.
