NORTHFIELD, Ohio -- The Summit County Medical Examiner's Office has determined that two children found dead after a house explosion in Northfield Center were murdered.
Their mother also died before the fire, which was set by their father, according to the Summit County Medical Examiner's Office.
The explosion happened on Jan. 11 at the home on Skyhaven Drive. It claimed the lives of Jeffrey and Cynthia Mather, both 43, as well as their two children: 12-year-old Alyson and 8-year-old Ruthie.
The Summit County Medical Examiner's Office said Jeffrey Mather showed signs of smoke inhalation, while his wife and children did not.
According to the medical examiner's report, the two children died of probable inflicted asphyxia. Their mother died of a Prozac overdose. There also was no evidence of smoke inhalation, according to the report.
The father, Jeffrey Michael Mather, died of burns. The report states that he burned himself after using gasoline to set fire to his home.
The report states "it is unclear which parent is responsible for the death of the two children or how the children were asphyxiated, and we will not speculate on the circumstances."
