Man charged with murder in alleged scheme to inherit his mother’s fortune

The man was rescued after his boat sank in 2016 but his mother was not. Investigators found the boat had been tampered with

A man found floating on a raft off the coast of Rhode Island in 2016 after his boat sank was charged in an indictment unsealed Tuesday with killing his mother at sea to inherit the family's estate.

The eight-count indictment released in federal court in Burlington, Vermont, also says Nathan Carman shot and killed his grandfather, John Chakalos, at his home in Windsor, Connecticut, in 2013 as part of an effort to defraud insurance companies, but he was not charged with that killing.
