We haven't been following the case of missing nursing student Michelle Le -- who disappeared May 27 from Kaiser Hospital in Hayward -- too closely, perhaps optimistic that she'd turn up. But police today have announced that, based on evidence found in the home of a "former" friend, that this is now a homicide investigation and the friend is now a person of interest in the case. We should note that the still unidentified remains found in a garbage bag in Sunnyvale over the weekend are not those of Le, and police have announced that they belonged to a Hispanic female, according to KTVU.
