SANDUSKY -- Police say a 19-year-old is charged with aggravated murder in the stabbing of an 11-week-old baby in northern Ohio.
Sandusky police say the man is due to be arraigned Friday. Investigators say he is related to the baby but is not the child's father.
Police Chief John Orzech says what led up to the stabbing is still under investigation.
Officers responded to the home where the suspect lives after getting a hangup 911 call late Thursday night.
Several adults were at the home where officers found the injured baby, including 19-year-old Denzel Castile who was arrested and later charged with aggravated murder.
Orzech says the suspect's grandfather suffered a small cut but was injured but not seriously.
He says the baby's mother wasn't there at the time of the stabbing.
