Youngstown detectives and the coroners office are investigating the death of a 3-day-old infant. The child's mother says the baby was bitten by a family dog.

It happened at a home on Valerie Street. The baby boy, named Aiden, was spending his first day at home. His mother Kristy Grim says they were both sleeping in the living room. The baby was on a blanket in a plastic laundry basket. 

"I was laying here next to him; he was on the floor in his bed. I woke up and he was screaming and he was covered in blood," Grim said.

She says they called 911 and requested an ambulance.

"While we were waiting for the ambulance we were trying to clean him up and stop the bleeding," said Grim.

The 21-year old mother says she saw bite marks on the child's head and she knew the dog had bitten the baby. Grim says the dog was never a violent dog and was actually protective of  the infant.

"He was never aggressive before; he never did anything like that. We don't think he meant to do it but we don't really know," Grim said.

The grandmother was also in the house and says the infant was breathing and responsive when she picked him up.

"He was breathing; we keep checking him because he thought he quit breathing but he would take a breath," Patricia Grim said.

When the ambulance crew arrived they said the child was dead. The dog, described as mix-breed shepherd weighing around 50 pounds is in being held in isolation at the county dog pound. It's fate is not known. Police say detectives are awaiting a ruling on the child's death by the county coroner.

"From there, the facts will be taken to the prosecutors office and there will be a determination whether there will be charges or not," said Lt. Doug Bobovnyik of the Youngstown detective division.

Grim says she didn't do anything and hopes there won't be any charges.

"I was so happy to have him, and I lost him in three days," Grim said.
