Ann Madsen was a witness against her corrupt business partner, Steven Green, in the murder of their employee Harry Rankmeyer. She and Green ran a baby food company, Nature's Way, with Rankmeyer as their CFO. When Rankmeyer discovered that Green was cutting costs by allowing tainted baby food to go on the market, Green ordered him killed; Madsen saw Green with the assassin, Nikolai Rostov, the day of Rankmeyer's murder.
