A Long Island father has been arrested after his 7-month-old son died in a parked car where the temperature reached at least 119 degrees. Devon Fenner, 25, has been charged with criminally negligent homicide in the death of his son Dominick on Tuesday. It's believed the infant was left in the vehicle for a half hour.

Fenner told detectives that he accidentally forgot to take Dominick out of the 2003 Toyota after dropping off his girlfriend at work and taking two other kids, a 7-year-old son and 4-year-old girl, to day care at 1 p.m. that day. The driver's side window had been rolled down slightly: "Unfortunately, cracking the window on a 90-degree day doesn't do much," said Insp. Kenneth Lack, a Nassau police spokesman. The temperature inside the car on Tuesday afternoon was written as 119 degrees in the criminal complaint.

Fenner called 911 when he realized he had left the child inside the car, and he wasn't breathing anymore. He was declared dead around 2:30 p.m., and Fenner was immediately arrested. Police said they found a “misdemeanor” amount of marijuana on Fenner, and will determine if he was high at the time.
