Bei Bei Shuai, 34, gave birth to a baby girl called Angel days after taking a lethal dose of the poison.
But despite efforts by doctors to save her life she died three days later from bleeding in her brain.

When investigator's searched Shuai's home they found an open packet of rat poison.
Rat poison pellets were also found on the floor and in a vacuum cleaner.
Shuai was arrested at her home in Indianapolis and charged with murder and infanticide.
She was due to make her first court appearance today.
