BROOKLYN, NY (CBSNewYork/Ap) —  Police say so far, no charges are being filed against the mother of the Brooklyn boy who was killed by a dog in his home.

Police say 4-year-old Jayelin Graham was mauled Friday night. His mother told police that when she tried to intervene, the dog, a male 100-pound Cane Corso mastiff, turned on her, too.

Even with the help of a neighbor who rushed to help after hearing her screams, she was unable to save the child, police said. Jayelin suffered wounds to his head, neck and torso and died at the hospital.

The Cane Corso mastiff is now with Animal Care and Control along with another dog found in the Brownsville home. Both will be held for at least 10 days as their fates are decided.

Jayelin’s two brothers, ages five and two, are staying with relatives as the Administration for Children’s Services investigates the incident.

The boy’s great-grandfather, Ameer Jamaal-Uddin, told The New York Times the dogs belonged to the mother’s boyfriend.

The apartment building’s superintendent, Kenny Risher, told reporters that he had occasionally seen the man training his dogs to bite in the street in front of the building. The family also owned a rabbit that was recently eaten by one of the dogs, as well as a parrot and a snake, Risher said.

“People were scared of those dogs,” he said. “This was a tragedy waiting to happen.”
