The Franklin County Coroner's Office is waiting on information from police interviews before ruling on a cause of death for a 4-year-old boy who was found unconscious in his Reynoldsburg home last week.

Alfred Hill died at Nationwide Children's Hospital July 12 after paramedics transported him there from his aunt's home at 1229 Baytree Court.

An autopsy was completed Saturday, July 14, but Reynoldsburg Police Lt. Jim O'Neill said Coroner Jan Gorniak is waiting for information from witness interviews that police are conducting.

He said Gorniak needs to determine whether injuries on the child's body were a contributing factor in his death.

There were marks on Alfred's body that didn't appear to be from a medical emergency or CPR, according to O'Neill.

"We think there was some contributing factor," he said. "Whether or not it's criminal in nature or accidental, we won't know until we put all the pieces together."

Alfred was in a bathtub at some point in the morning, according to police, but it's unclear whether that contributed to his death.

The 4-year-old had been dropped off at his aunt's apartment by his mother, whose name is Ashley Bennett, according to birth records. Two of Bennett's other children, a 7-year-old boy and an infant boy, also were at the apartment at the time of Alfred's death, O'Neill said.

The boy's father, also named Alfred Hill, 26, left the apartment when paramedics initially arrived to treat his son in the morning. He was wanted on outstanding rape and kidnapping charges filed a year ago, police said.

When police arrived a few hours later to secure the apartment as a crime scene -- after they were told by witnesses that the boy's death might be suspicious -- a maintenance man from the apartment complex said Hill was at another unit nearby.

Hill fled, but officers were able to catch and arrest him. Franklin County Municipal Court Judge Scott VanDerKarr set bond at $1 million on July 13 when Hill made his initial court appearance on the rape and kidnapping charges.

Those charges stem from July 6, 2011. Police say that on that date, Hill abducted and raped a woman, first at an abandoned home and then at his residence, according to a police report read in court. She escaped after being held for 14 hours, police said.
