In what police say is an extremely rare and disturbing case, a Sacramento woman was arrested this morning for allegedly killing her 6-week-old daughter in March by placing her in a microwave oven.
Ka Yang, 29, was arrested at her Sacramento home this morning and charged with homicide after a three-month investigation into what caused unusual burns on the child, Mirabelle Thao-Lo, who was found dead on the afternoon of March 17.
Sacramento police spokeswoman Laura Peck said there have been only three previous cases involving a child being burned in a microwave, and that detectives studied those cases and consulted with medical experts and pathologists before making the arrest.
"It was a lengthy investigation to determine how these burns occurred," Peck said. "When the officers arrived on scene they immediately saw there were unexplained injuries because of the burns. That led to this very lengthy, involved investigation to determine how these unusual and rare injuries occurred."
The infant's fourth-degree burns were among the worst investigators at the Sacramento County Coroner's Office had seen, coroner's spokesman Ed Smith said.
