The mother of a 2-year-old boy who was found dead in a bedroom where the thermostat was set so high that the temperature reached 100-plus degrees has been sentenced to two years in prison.

A Toledo judge sentenced 31-year-old Megan Giltz on Thursday. Giltz pleaded no contest in May to endangering children and obstructing official business in the Oct. 6 death of her son, Robert.

The Blade in Toledo reports that an autopsy concluded the toddler likely died from heart problems, although dehydration from a hot environment was cited as a significant condition.

Authorities say Giltz was charged with obstruction for initially lying to police about how long her son had been in the room and how much nourishment he'd had.

Giltz' attorney, Peter Rost, declined to comment Friday.
