The death of Benjamin Seitz, a 15-month-old Connecticut boy who was left alone inside a car last month, has been ruled a homicide, the chief state medical examiner’s office said Thursday. The medical examiner said that the boy had died of “hyperthermia due to environmental exposure.”

The toddler from Ridgefield, a town in Fairfield County, reportedly died after his father left him alone in the car and went to his job at a computer technology company. Police officials reportedly said that Kyle Seitz was scheduled to take his son to daycare that morning but instead went to his office and after an "extended period of time" realized that his child remained in the car. According to a report issued by Danbury Hospital, the temperature had reached more than 80 degrees Fahrenheit that day.

"The criminal investigation is ongoing, and as such this office will have no comment on the status of the details of the investigation, including the autopsy," State's Attorney Stephen Sedensky III, said, according to News Times. "The autopsy report is one factor to be considered by the state's attorney in the evaluation of the incident once the investigation is complete.”

He reportedly added that no warrant had been issued for Seitz’s arrest as it was not yet determined if charges would be filed against the toddler's father. According to News Times, a legal expert said that a ruling of homicide does not always necessary mean that a crime has been committed.

"The homicide ruling just means that the death was not an accident or due to natural causes," William Dunlap, associate dean of Quinnipiac University's law school, reportedly said.

The mother of the infant, Lindsey Rogers-Seitz, who also has two daughters, told The Associated Press last month that she had forgiven her husband as he is a good father.
