Documents show Carman could get $7M from slain grandfather

First, his grandfather was murdered. Then his mother disappeared at sea. Now, we know how much the Vernon, Vermont, man once accused of killing his grandfather stands to gain.

Court documents show Nathan Carman could get $7 million from his murdered grandfather's estate. His family is trying to stop that from happening with the help of a law called the "Slayer Rule." It says if you kill a relative for money, you can't get that money.

In the last six years, tragedy seems to have surrounded Nathan Carman. Dec. 21, 2013, his grandfather, John Chakalos, was shot and killed in Connecticut. Nathan, who was living in Vernon at the time, was a suspect. There were no arrests. Chakolos' willed Nathan's mom, Linda, a portion of his $29 million estate.

Sept. 25, 2016, Nathan and Linda were lost at sea for seven days. Nathan was rescued 100 miles off the coast of Martha's Vineyard floating alone in a raft. He claimed they had engine problems and his boat filled with water. Linda was never found and is presumed dead.

Investigators searched Nathan's home for evidence following the fishing trip. In December 2016, more than a dozen federal agents swarmed a house off Route 9A in Spofford, reportedly owned by the Chakalos family.

This past January, Linda Carman's insurance company filed court documents saying Nathan made faulty repairs to the boat the day before it sank, claiming he knew it wasn't fit for sailing. Then in April, a Connecticut judge denied Nathan's request to seal a warrant that disclosed he was a suspect in his grandfather's death.

Nathan Carman is not charged with either death and has denied any involvement.
