SPRINGFIELD, Mo. -- New information tonight in the case of the Springfield woman and her daughter who allegedly poisoned and killed family members using antifreeze.
A search warrant (read documents below) was unsealed Thursday in the case detailing what was taken from the home as evidence in the case. It revealed that police received another anonymous tip regarding suspicions about Diane Staudte's behavior as early as September 2, 2012.
It was a tip this June that led police to arrest Diane Staudte and her daughter Rachel. Both are in the Greene County Jail charged with two counts each of murder and assault for the poisoning of Diane's other daughter Sarah and armed criminal action.
The search warrant was served on Staudte's home at 1644 W. Swan. It shows automotive fluids taken from the home like windshield de-icer, washer fluid and antifreeze. Antifreeze is what police suspect and Diane Staudte admitted to using to poison and kill her husband Mark and her son Shaun, 25. That's 9 months before police arrested Staudte and her daughter this month.
The search warrant then goes on to say that on September 2, 2012 a police service representative took an anonymous call in the case.
The male caller said he was afraid that Diane Staudte may have something to do with the deaths of her husband Mark, who died in April 2012, and her son Shaun, who died in September 2012. The warrant does not say what, if any action was taken by police after that initial tip.
