Mother Stephanie Mae Dunham convicted in death of 3 children OKLAHOMA CITY, July 12 (UPI) -- An Oklahoma woman was sentenced to 18 years in prison after her three children burned to death in her motor home, officials said. Stephanie Mae Dunham, 27, who is four months pregnant, wept throughout Wednesday's court proceedings, her hands and arms peppered with scars and burns. "She was doing meth the day her three children burned to death," said Assistant District Attorney Pamela Stillings. The Oklahoman reported Oklahoma County District Judge Jerry Bass choked back tears as he handed down Dunham's sentence, calling the case one of the "saddest" he's presided over. Dunham pleaded no contest in May to three counts of child neglect, as well as two misdemeanor drug charges and a felony charge of possessing methamphetamine in the presence of a child younger than 12. Prosecutors accused Dunham of leaving her four children alone in her mobile home and latching the door on Jan. 4, 2011. When a fire broke out, 4-year-old Christopher Lee Dunham, 3-year-old Chrystal Ann Dunham and 1-year-old Kailey Mae Dunham were trapped. The three children died of burns and smoke inhalation. Investigators found one of the children next to the door clutching the family dog. Infant Kailey's body was found in the front seat of the mobile home. The father, Christopher Lee Dunham, was sentenced to 18 years in prison for similar charges. He admitted to cooking methamphetamine in the mobile home, Stillings told Bass.
