Mariah Butler, 28, left 4-year-old Logan Starling in a van outside Elite Preparatory Academy on Oak Ridge Road on September 28, 2018.

Prosecutors dropped the most serious charge, aggravated manslaughter of a child, a first-degree felony, in White's courtroom Monday. That crime is punishable by up to 30 years in prison.

Butler was in a relationship with the boy’s father at the time.

She drove Logan and four other children to school that morning, but Logan was left behind in the van.

An autopsy said Logan died of hyperthermia, or an abnormally high body temperature.

His core temperature was 108 degrees when he was found.

The temperatures in van ranged from 106 to 121 degrees.
