The third video here explains some of the crazy stuff he found. Some of which is not from "this world".
RIP Roger...These objects have been scientifically investigated by some of the most prestigious laboratories in the world including Los Alamos National Labs, New Mexico Tech, Seal Laboratories, Southwest Labs, the University of Toronto, York University, and the University of California at San Diego. Their findings have been baffling and some comparisons have been made to Meteorite Samples. In addition some of the tests show metallurgical anomalies such as highly Magnetic Iron that is without crystalline form, combinations of crystalline materials mixed common metals, growth of biological tissue into or out of metallic substances, as well as isotopic ratios not of this world.
