Attorneys for a Chinese immigrant accused of killing her baby by attempting suicide while she was pregnant say Indiana prosecutors haven't proven that the rat poison she ate caused her daughter's death.
Defense lawyers Wednesday will try to persuade a judge to exclude the testimony of the pathologist who performed the autopsy from Bei Bei Shuai's murder trial.
Shuai's attorneys claim in court documents that a medication given to Shuai could have mimicked the effects of rat poison. They also claim the pathologist never considered any alternative cause of death, but the doctor who treated the baby testified there were other possibilities.
Shuai was freed on bond in May after more than a year in an Indianapolis jail.
She has the support of several women's rights groups.
