SACRAMENTO police arrested a 29-year-old mother yesterday after an investigation found her baby had likely died from burns suffered inside a microwave oven.
Ka Yang was being held without bail in Sacramento County Jail on suspicion of murder and assault.
She was arrested three months after her otherwise healthy 6-week-old daughter, Mirabelle Thao-Lo, was found dead in the family home on March 17.
Police described the child as suffering "extensive thermal injuries". Officer Laura Peck said the arrest took so long because investigators had to pinpoint what they believe is the cause of death by looking for other cases involving similar injuries.
They found three in the US, all after children were burned in a microwave.
"This is rare. The injuries were obviously very unique," Peck said. "There have been only three other documented cases in the entire country where the injuries were consistent with this case. Those children were also burned and placed in the microwave."
