Twenty-five days into excavation efforts on agricultural property in Linden, FBI personnel and technical experts have dug to a depth of approximately 65 feet below grade within the old well site.
Thus far, no human remains have been discovered. Excavation of the soft, sandy fill dirt within the well has proceeded relatively smoothly. All fill dirt is conveyed to the surface to be sifted, ensuring that no materials are overlooked.
A safety area around the well must be excavated in tandem with well excavation to ensure that the teams have enough room to operate safely and respond both to possible evidence and to emergencies.
This site is the second well site to be excavated along Flood Road. In January 2012, San Joaquin County Sheriff's Office excavated a well on an adjacent parcel. These efforts resulted in the recovery of the remains of three females and one fetus, victims of convicted killers Wesley Shermantine and Loren Herzog.
The collaborative team of FBI personnel and technical experts began preparation at the well site on Jan. 7.
