Andrew "Andy" Trudeau was a police inspector for the San Francisco Police Department and the partner of Darryl Morris. He was a childhood friend of the Halliwell sisters, as he grew up in close proximity to them, and had an on again-off again romantic relationship with Prue since high school. Andy later learned the truth about Prue and her sisters. Seeking to protect them from Rodriguez, he was struck by an Energy Ball thrown by Rodriquez and was tragically killed.
