A one-month old baby boy has died after being found inside a car on one of the hottest days of the year in Zanesville.

Around 6:25 p.m. Tuesday evening, the Muskingum County Sheriff’s Office received a call about the baby not breathing at Eagleview Apartments located at 80 Eagleview Drive in Zanesville.

Deputies found the baby unresponsive inside the car and performed CPR until EMS responders arrived, but the medics were unable to save him.

The baby was pronounced dead on the scene.

According to Sheriff Matt Lutz, the investigation is ongoing, and while an autopsy has not yet been done, the early indication is that the baby died due to high temperatures.

Temperatures in Zanesville reached a high of 93 degrees on Tuesday.

No arrests have been made at this time, but authorities have contacted the parents and a criminal investigation is underway.
