Ind. woman charged with fatally poisoning husband

COLUMBUS, Ind. -- A judge has entered a not guilty plea for a southern Indiana woman charged with fatally poisoning her estranged husband with morphine and muscle relaxants to collect on a $100,000 life insurance policy.

Fifty-one-year-old Tami Duvall of Jeffersonville was in a Bartholomew County court for an initial hearing Tuesday on charges of murder and insurance fraud for the 2007 death of Alan Duvall at her then-home in Columbus.

Court documents say Alan Duvall's blood contained more than 82 times the maximum therapeutic level of morphine. His death was initially called accidental alcohol poisoning based on his blood-alcohol level of 0.436 percent and Tami Duvall's accounts that he essentially drank himself to death.

Authorities say she possibly stole the drugs and poisoned food she made for Duvall.
