Ron Wyatt was an amateur archaeologist who claimed to have located the Ark of the Covenant under the hill on which Christ was crucified at Calvary, also known as Golgotha, very near the garden tomb. He even claims to have scraped dried blood off the ark casing and to have subjected it to DNA testing and said the lab reported the result of only half the chromosomes normal humans have, consistent with having only one human parent. Many sites dedicated to his discoveries like ArkDiscovery.com tell about this. Jonathan Gray's book "The Ark of the Covenant" investigates the claims in depth.
