The Sacramento office of the Federal Bureau of Investigation announced at a Monday morning briefing that it was restarting the excavation process in the hopes of finding more victims of the so-called Speed Freak Killers. 

The new digging will happen near the town of Linden, and not far from another abandoned well where the bodies of three people and a fetus were found last year.

FBI agent Herb Brown said the new excavating will last two to three weeks, during which time they plan to dig about five feet per day to reach the well's depth of 50 feet.

Brown said the excavation was scheduled following information provided by law enforcement and Shermantine himself.

It is not clear how many more victims of Shermantine and Herzog may be located.
