I'm trying to find a movie and I cannot think of the name - I know it starts with a guy out running. When he gets home he finds his wife/girlfriend dead in the tub. He rents a room he shares with a woman. He locks her in her room and she poisons him with bacteria she was growing in a petri dish.

Chosen answer: It could be the 1992 TV movie, Deadbolt. Starring Justine Bateman as the girl held prisoner by Adam Baldwin. She put some sort of bacteria in his dessert.
