The death of a Connecticut baby boy after being left in a hot car for several hours has been ruled a homicide.

Benjamin Seitz, who was 15-months-old, died July 7 after his father left him inside his car while he went to work in Ridgefield. The Connecticut medical examiner's office ruled Seitz died of hyperthermia from environmental exposure, NBC New York reported. The temperature outside the car that day was 88 degrees.  

Seitz' father, Kyle Seitz, has not been arrested for his son's death. State prosecutors are meeting with police to determine if charges should be brought. No other details about the baby's death have been released.

"The criminal investigation is ongoing and as such this office will have no comment on the status or details of the investigation including the autopsy report," Attorney Stephen J. Sedensky III, of the Judicial District of Danbury, told the station.

Benjamin's father was supposed to drive him to a daycare but instead drove to his job at Owl Computing Technologies in Ridgefield.

Kyle Seitz parked his car and went to work, leaving his son in the vehicle for "an extended period of time" in the sweltering July heat, investigators told the station.

The father left work and went to the daycare to pick up his son. Realizing he wasn't there, Kyle asked the staff if his wife already took him. Employees said his wife was never there.

Kyle rushed Benjamin to Danbury Hospital when he realized he was still in the car, the baby's mother and Kyle's wife, Lindsay Rogers-Seitz, told NBC New York.

Rogers-Seitz told the Associated Press she has since forgiven her husband, saying he is a good father.

Each year, over 30 children die of heat exposure in the U.S. from being left in hot cars. Temperatures inside cars can reach over 100 degrees even if the weather outside is in the 60s, the AP reported.
