Pair admit to poisoning relatives with antifreeze

KANSAS CITY, Mo. – A Missouri woman and her daughter confessed to fatally poisoning two relatives with antifreeze and attempting to kill a third over a 14-month period, according to court filings.

Diane Staudte, 51, of Springfield, was charged Friday with two counts of first-degree murder, one count of first-degree assault and one count of armed criminal action. Her daughter, Rachel Staudte, 22, was charged with the same counts Saturday.

Diane Staudte initially told police that her husband, Mark Staudte, 61, hadn’t been feeling well and suffered from seizures before his April 2012 death, according to an affidavit. She said her son, Shawn Staudte, 26, had been sick with flulike symptoms before his September death.
