'DNA Proves Pitbull Sexual Attack Possible'
Lockport Police say DNA results show no human involvement in the sexual assault of a two year old boy July 8th.
Jessica Weinstein: "So this proves that it really can happen?"
Chief Neil Merritt, Lockport Police: "I don't think that there's any doubt because there's a number of witnesses, because this occurred inside, then the dog ran out onto the porch."
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, named "Bear", had sodomized the toddler. The mother screamed, scaring the dog out of the house, but the dog was still attached to the baby.
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. Castillo says the boy was vomiting and bleeding.
The baby was rushed to Women and Children's Hospital where the toddler underwent reconstructive surgery. Hospital officials are no longer verifying that he is a patient there.
