A person familiar with the investigation says the shooting death of a 2-year-old boy in Newark appears accidental.
The person says neighbors reported hearing a man yelling "I'm so sorry" repeatedly and there was evidence someone tried to clean blood up from the scene.
The person spoke only on condition of anonymity because the person was not authorized to discuss the details of the case.
Authorities are searching for a man in his 20s who was with Mikhy Robinson's mother when they brought the boy to Newark Beth Israel Medical Center shortly before 10 a.m. Friday.
Police are questioning the mother and searching for the man, believed to be driving a white Pontiac Grand Prix.
