I wouldn't say it's "hard to believe" that no bodies were found. The bay currents generally tend outward; and Alcatraz Island sits basically right in the middle of the outward flow, not too far out from the Golden Gate Bridge. It's pretty much a straight shot out the bay, actually. Meanwhile Scott Peterson seems to have made the mistake of dumping his wife's body somewhere around Richmond, where currents are more stationary. Her body was also dismembered, increasing the chance that parts of it -- such as the fetus -- would eventually be found.
