Most states have a law that declares that someone who murders another person cannot inherit anything from the assets of the deceased. These are known as slayer statutes. That trick is proving who was responsible for a death.
A recent estate battle in New Hampshire sounds more than a little suspicious. In 2013, John Chaskalson, a multi-millionaire, was found shot to death. Prior to his death, his grandson Nathan Carman had purchased a weapon and bullets of the same caliber as the one that shot Chakalos.
The estate was divided equally between Chakalos' four daughters, including Carman's mother Linda Carman.
In 2016, Nathan and Linda Carman went out on a boat. Something happened to the boat and Nathan was eventually found adrift by a Chinese ship, miles away from where he claimed the boat had sunk.
Linda was never found.
Nathan had claimed that he personally repaired holes in the boat to make it seaworthy, but insurance companies in court said the repairs were shoddy, according to the Daily Mail in "Heir, 23, accused of murdering his millionaire grandfather, 87 and sinking the boat his mother was sailing off Rhode Island could still get $7 million inheritance despite relatives legal fight to stop him."
Linda Carman's three sisters have filed in court to prevent Nathan Carman from receiving any part of his mother's estate.
They accuse their nephew of murdering both his grandfather and his mother for the money.
However, investigations into the deaths remain open and no suspects have been officially named.
It is possible that Nathan could have been involved, but that has not been proven.
If Nathan committed the crimes, then he would not be eligible to receive any portion of the estate. Proving that he did so beyond a reasonable doubt, could be difficult.
