BALSAM LAKE, Wis. (AP) - Authorities say a Wisconsin toddler found dead in the trunk of a car likely died of hyperthermia.
The Polk County Sheriff's Department has released a statement summarizing preliminary results of an autopsy on 2-year-old Isaiah Theis.
The autopsy found the boy was normally developed and well-nourished and had suffered no life-threatening injuries or bone fractures. He also wasn't sick.
The statement listed the cause of death as probable hyperthermia, a condition where body temperature spikes.
Toxicology reports are pending.
The boy disappeared Tuesday night. A sheriff's deputy found his body in the trunk of a locked car outside the boy's home near Centuria late Wednesday evening after a day of blistering heat.
