Whitney Houston died on Feb. 11, 2012, and her daughter may die on the third anniversary of that date. Sources tell Page Six that Bobbi Kristina Brown's family has agreed to remove life support, but Brown's grandmother, Cissy Houston, suggested they wait until tomorrow to do so. They will take Brown, 21, off life support at the stroke of midnight as a way to symbolically keep mom and daughter together, a family source says. The Brown and Houston sides of the family have been arguing, but they are in agreement that it's time to say goodbye, sources say. "This is the only thing they can agree on—that she's gone [brain-dead], and there's nothing more [that] can be done for her," one explains. Filmmaker Tyler Perry has been acting as a sort of mediator, and he'll also make the funeral arrangements.
Meanwhile, the investigation into how Brown ended up facedown in her bathtub continues. Sources tell WSB-TV she had injuries to her face and mouth when she was found, which, sources tell TMZ, has led investigators to focus on her boyfriend, Nick Gordon. Sources say there is a history of violence between the pair. Sources also tell People the investigation is focused on "drug use and possibly cover-up to remove evidence from the crime scene."
