Mom Breaks Silence Over Baby's Death As Investigation Mounts

SACRAMENTO (CBS13) -- Ka Yang said she had been trying to have a daughter for two years before giving birth to Mirabelle Thao Lo, after already giving birth to three boys.

Mirabelle's death was a tragic accident, caused by a seizure, according to Yang, but the investigation into the baby's death has concluded the baby died from a more sinister cause.

The soft-spoken mother told CBS13 she was holding her daughter while sitting at her computer desk when she suffered a seizure and blacked out. When Yang woke up, Mirabelle wasn't breathing.

"I never thought that with my seizure I will lose my little girl," she said.

The firefighters who responded to the call found the girl dead and called police to investigate, and the Sacramento County coroner has ruled that Mirabelle died from burns on her body. Investigators have not said how they believe the girl sustained the injuries.

"We do have forensic evidence from the scene that is being processed and we're waiting for the results of that evidence," said Officer Laura Peck.

Yang says the proof of her claim lies in her medical records, which she says shows a pattern of seizures since she was 14 years old. She said she believed her current medication would control her condition.

When CBS13 returned for a follow-up interview Wednesday to ask about the burns on Mirabelle, Yang avoided our cameras.

Yang's other three children have been ordered into the custody of her grandparents.
