(Oak Ridge National Laboratory researcher Arpad) Vass said that, considering the quantity and the types of markers of human decomposition found, the cadaver dog's response, and the probing exercise, he found enough evidence to warrant further testing at a deeper level and a full scale excavation at Barker Ranch, according to the report he issued to law enforcement.
"I'd recommend a dig, excavate the sites," said (police detective Paul) Dostie, who reviewed the report.
