Federal and state authorities searched an abandoned New Hampshire property owned by a family marred by homicide and a recent death at sea on Thursday, a source confirms.
The Spofford property was owned by John Chakalos, the grandfather of the man who survived an apparent shipwreck and whose 2013 murder in Connecticut remains unsolved.
The Keene Sentinel reports there were at least a dozen people in "haz-mat style suits" and about 30 vehicles on the property during Thursday's search.
"The FBI's Evidence Response Team was assisting a multi-agency investigation. Due to the ongoing investigation, we're going to decline further comment," an FBI Boston spokesperson said in a statement on the property search.
What Happened to Nathan Carman's Mother?
Nathan Carman, 22, was found in a lifeboat near Martha's Vineyard in late September, eight days after an apparent shipwreck with his mother, Linda Carman. Linda Carman, who was Chakalos' daughter, was not found and is presumed dead.
Carman's Vermont home was searched shortly after he was found, and an affidavit shows authorities were looking for evidence in connection with his mother's presumed death. He also previously told the Associated Press that he had nothing to do with his grandfather's murder and didn't hurt his mother.
