DiNardo told investigators he picked up Patrick on July 5 at his home in Newtown with an offer to sell him four pounds of marijuana for $8,000. When the man only brought $800 to the exchange, DiNardo said, he led him to a remote part of his family's property and shot him with a .22-caliber rifle. DiNardo, whose parents own the vast acreage, used a backhoe to dig the six-foot ditch where he buried the man, DiNardo later said.
