A 5-month-old baby boy who New Jersey prosecutors say was beaten by his father has died after more than a week in the hospital.
Bergen County Prosecutor John Molinelli says the baby died Thursday at Bellevue Hospital in New York.
Molinelli says charges against the baby's father, 38-year-old Yoseop Choi, will be upgraded to homicide.
The Fort Lee man was being held on $750,000 bail and charged with aggravated assault and child endangerment. A message left with Choi's attorney wasn't immediately returned.
Authorities say Choi brought the boy to the hospital July 28 in cardiac arrest. He also had a severe head injury and a healing rib fracture.
Prosecutors say Choi violently shook and assaulted his son during a two-month period.
