New details are out in the investigation into the deaths of two Bradley County boys.
Authorities say officers received a tip Friday about possible drug activity at the boys' mother's home on Keith Valley Road.
Regardless, no arrests have been made.
The medical examiner says 5-year-old Leland Bates' core temperatures were at least 105 degrees. Preliminary findings show the boys died of overheating.
Earlier this month, the boys' mother told police he boys were involved in a near-drowning. However, no pool or body of water was at the scene.
