Police in North Carolina are investigating after an 8-month-old child was found dead in a car when his mother went to a day care center to pick him up.

Wilmington police spokeswoman Linda Rawley told local news outlets the child apparently was never dropped off Wednesday and may have been in the car from 9:30 a.m. until the mother went to the day care Wednesday evening.

Authorities haven't released the names of the parents or child. The cause of death hasn't been determined.

Meteorologists say the outside temperature reached 86 degrees and it could have reached 135 degrees in the car.

Assistant Police Chief Jim Varrone said he couldn't confirm whether the child was in a car seat.
