Pit Bull Rapes 2-Year-Old Buffalo, NY -- A disturbing and violent attack leaves a toddler in serious condition at Women and Children's Hospital. Neighbors heard a mother screaming that her child was being raped. Lockport Police received a 911 call from a frantic City of Lockport mother Sunday afternoon. The mother told Lockport Police that she left her two-year-old unattended for a short time and after hearing the baby scream, she ran to see what was wrong. When she got in the room, she told Lockport Police the dog had sodomized the toddler. The mother screamed, scaring the dog and it ran out of the house. One neighbor told 2 On Your Side, she heard the mother screaming "the dog is raping my baby." Neighbors ran to help, but only one man was able to get the dog and child apart. Anastacio Castillo says "I tried to get the dog away from the baby, the dog was already inside the baby." When the baby was finally free, he was visibly sick. The baby was rushed to Women and Children's Hospital where the toddler underwent reconstructive surgery. The dog is being held at the Niagara County SPCA for evaluation. An animal behavior specialist is scheduled to evaluate the Pit Bull. The Niagara County District Attorney's office is assisting Lockport Police with the investigation. Miranda Workman, behavior specialist at Purrfect Paws in Amherst says, "Most likely this is not a learned behavior. Dogs intact, not spayed or neutered have a higher hormonal drive." She urges parents to never, ever leave their children alone with a dog.
