Amanda Chapin, 50, of Monroe, was charged Dec. 28 in Lafayette County. Authorities say she poisoned her 70-year-old husband, Gary Chapin, three times during July and August by putting barbiturates in his coffee, the Wisconsin State Journal reported.
According to a criminal complaint, the couple got married in March. Following the wedding, Amanda Chapin forged the signature of one of her husband's children on a power-of-attorney document, then demanded her husband amend his house deed so she would get the home if he died.
The complaint says she poisoned her husband for the first time less than three weeks after the quit claim deed on the house was authorized.
The third time he drank the allegedly poisoned coffee in early August he fell into a coma that lasted for four days, the complaint said. Blood work showed barbiturates in his system came from drugs he used to euthanize animals.
Gary Chapin's son subsequently filed a restraining order against Amanda Chapin on his father's behalf and Gary Chapin has filed for divorce, according to online court records.
According to the criminal complaint, Amanda Chapin violated the restraining order in September when she sent her husband a suicide note via email, writing that she had decided to kill herself because his children would "destroy" her. She repeatedly denied poisoning him.
She survived the suicide attempt after paramedics took her to a local hospital. Gary Chapin filed for divorce the next day.
Online court records indicate attorney Adam Witt is representing Amanda Chapin in the homicide case. The Wisconsin Bar Association's website indicates Witt serves as a public defender in Green County. He didn't immediately respond to an email seeking comment.
