LOUISVILLE, Ky. (WDRB) -- Police say Harlan County, Kentucky woman is charged with manslaughter, after her 3-year-old nephew died in a house fire while she was out watching go-cart races.

According to a news release from Kentucky State Police, the house fire took place just before 9 p.m. on Saturday, in the 200 block of Abe Lane, in Coldiron, Kentucky.

Police say earlier in the day, 37-year-old Amanda Brock left her 11-year-old son at home to watch her 3-year-old nephew while she left to watch go-cart races in Letcher County.

While she was gone, police say the home caught fire, and Brock's 11-year-old son ran to a neighbor's house for help. By the time neighbors arrived, the home was engulfed in fire and smoke, according to the arrest report.

The body of the 3-year-old was found inside the home by firefighters from the Sunshine and Wallins Fire Departments. His body is expected to be sent to the State Medical Examiner's Office in Frankfort, so an autopsy can be conducted and the cause of death can be determined.

As caretaker for the 3-year-old, police say Brock was responsible for his protection and well being. She was arrested and charged with second-degree manslaughter and first-degree wanton endangerment. She is currently being held in the Harlan County Detention Center.

The cause of the fire is not known at this time.
