The woman, Ka Yang, 29, of Sacramento was arrested and charged Tuesday with the murder of her 6-week-old baby daughter, Mirabelle Thao-Loa, that occurred March 17, according to Fox News
In March, Sacramento Police responded to a call to Yang's residence, where fire department investigator's who were already on the scene had pronounced the baby dead from unknown causes. She had visible facial injuries and witnesses had reported that Mirabelle was alleged dropped on a sidewalk, possibly while having a seizure.
After three months of investigative work, that included comparing the infant's injuries to those of three other babies who died after being placed in a microwave oven, investigators concluded the cause of death was thermal burns, received from a microwave, reported Fox.
According to the police report, a pacifier was found in the microwave by investigators at the home. The clothing that Mirabelle was wearing and her hair were not burnt, said the news reports
Associated Press reported
. Yang "told investigators she blacked out, but later admitted she had lied to the police officers. She told them she thought she may have a split personality."
Yang is being held in the Sacramento County Jail, where she is ineligible for bail, according to the jail website
. Yang has three other children, all boys, who were removed from the home Tuesday when she was initially arrested and charged with the horrific crime.
The mother of four, "also faces a special circumstance that the murder was intentional and involved torture, which, if found true, could make her eligible for the death penalty or life without parole," according to the Sacramento Bee
Yang, who did not enter a plea at Thursday's hearing, has yet to give detectives any idea about what happened on that day, three months ago, when the newborn baby Mirabelle was killed or what events may have led up to the alleged murder, said
