That's according to the Sacramento bounty hunter who convinced Wesley Shermantine to reveal the locations of his victims.
Leonard Padilla told ABC7 Monday night that Shermantine told him about the new well on Sunday.
Some 1,000 human bones from as many as 30 victims of the killing spree in the 80s and 90s have already been recovered from a well in the town of Linden.
Last week, searchers used dogs to check out a second well.
