Bob Saget's head injury death a tragic reminder of Natasha Richardson's

The death of "Full House" star Bob Saget from a head injury is both a cautionary tale and a reminder that it's happened before.

On Wednesday, Saget's family released a statement stating that authorities had "determined that Bob passed from head trauma."

"They have concluded that he accidentally hit the back of his head on something, thought nothing of it and went to sleep," the statement read. "No drugs or alcohol were involved."
