A 2-month-old boy was killed Sunday afternoon and his mother was injured when the family's pit bull attacked the child inside their Dallas home, police said.
Police said a man left his son — later identified as Brayden Wilson — alone with the dog as he went outside to turn on their sprinkler system at their home on the 6800 block of Beechnut Street.
When the man walked back into the house, the dog was attacking the child as he sat in a bouncing chair, police said.
The dog then attacked the boy's mother, biting her twice.
Police said the father was able to grab the dog by its neck and drag it outside, where it was shot and killed.
The child and his mother were both taken to Children's Medical Center of Dallas for treatment where the toddler was pronounced dead. The mother's condition is not known.
Dallas Animal Control was called to collect the dog's remains.
No further information was released and the incident remains under investigation by police and Child Protective Services.
At this time, no charges have been filed against the parents and police said the case will be referred to a grand jury.
