On March 17, 2011, Ka Yang of Sacramento, California, put her 6-week-old daughter, Mirabelle Thao-Lo, in a microwave oven for up to five minutes, killing the infant.
Yang, now 34, was sentenced on Dec. 18 to at least 26 years in prison for first-degree murder and assault, although she could remain behind bars for the rest of her life, the Associated Press reports.
At the time of the infant’s murder, Yang told investigators that she had a seizure and when she regained consciousness, her baby was injured.
Yang told CBS that she dropped her baby on a space heater while she was blacked out.
After a three-month investigation, authorities determined Mirabelle had died as a result of being burned in a microwave oven. According to prosecutors, the infant had fatal thermal injuries, but her clothes and hair were undamaged. Police found a pacifier in the microwave and concluded that Mirabelle was left in the appliance.
“The injuries aren’t seen that often,” Sacramento Police Sgt. Norm Leong told CBS in 2011. "In fact, we couldn’t find three other cases in the nation that had injuries caused by a microwave."
Yang also underwent a polygraph test, the results of which indicated that she was lying.
Although Yang's attorney argued in court that her client had a history of seizures and wasn’t aware of her actions, paramedics said she wasn’t disoriented when they arrived at the scene.
Yang has three other children who were placed in the custody of her grandparents in 2011.
