The death of a 1-year-old girl found unconscious in her family’s apartment in Queens was not the result of a dog mauling, the city’s medical examiner ruled, as the mysterious circumstances of her death are now being investigated.

Officials say the baby’s injuries from the family dog happened after she had already died, though the exact cause of death remains under investigation.

A mother says her daughter was killed by a puppy while sleeping in their Queens apartment.
