Nathan Carman, the Vermont man at the center of separate probes into the murder of his wealthy grandfather and disappearance of his mother, tossed his rifle into the ocean after the fatal shooting of his grandpa in 2013, an insurer alleged in a recent court filing.

The document, filed Friday in federal court in Rhode Island, was submitted by the National Liability & Fire Insurance Company and Boat Owners Association of the United States. The parties are suing Carman, 24, in an effort to quash his $85,000 insurance claim on his sunken vessel.

Regarding the alleged murder weapon in the December 2013 slaying of Carman’s grandfather, John Chakalos at his home in Windsor, Conn., the filing said Carman “and the Sig Sauer [rifle] were criminally involved in his grandfather’s murder on the night of December 19/20, 2013. The Sig Sauer rifle was capable of firing the same caliber rounds which killed his grandfather and Nathan Carman was the last known person to see him alive. In the morning Nathan Carman went fishing on a head boat out of Point Judith, R.I., jettisoning his Sig Sauer rifle which now lies at the bottom of the sea.”

The plaintiffs didn’t provide specific details on the basis for the allegation about the rifle disposal.


Carman’s lawyers didn’t immediately respond to a request for comment on the filing. Law enforcement officials have labeled Carman a person of interest in Chakalos’s murder, but he hasn’t been charged and adamantly denies killing his grandfather.

The plaintiffs in the Rhode Island lawsuit allege that Carman killed Chakalos and then intentionally sank his boat in September 2016 when he and his mother, Linda, were on board. Carman was later rescued but his mother hasn’t been found.

With Linda Carman’s presumed death, her share of Chakalos’s $44 million estate would go to Nathan, her only child. Nathan Carman has said the sinking of the boat was accidental, but plaintiffs in the Rhode Island lawsuit maintain he made suspicious alterations to the vessel before setting out on a fishing trip with Linda.


“Defendant Nathan Carman executed a common scheme with striking, chilling, parallel losses of evidence, omissions, concealments, misrepresentations, false testimony, and fraud to procure a substantial inheritance by causing first his grandfather’s murder and second his mother’s death at sea through the sinking of his boat which Nathan Carman intentionally, knowingly, and/or criminally rendered unseaworthy before leaving port in an effort to claim its $85,000 hull insurance proceeds,” the filing said.

The document also said that after Chakalos’s murder, Carman gained “unrestricted access” to roughly $587,000.

“Nathan Carman’s false testimony precluded Plaintiffs’ and others’ efforts to recover the sunken boat and their ability to inspect it and the unseaworthy alterations he made to it in furtherance of his fraudulent marine insurance claim so that he might obtain $85,000 in hull insurance proceeds,” the document said. “Similarly, Nathan Carman attempts to mislead Plaintiffs and others into concluding he did not criminally cause his mother’s death and is entitled to her ¼ share of a multi-million dollar family trust owning several nursing homes.”

The next hearing in the civil case in US District Court in Providence is set for Jan. 29. The hearing will deal in part with a woman identified by Carman’s lawyers as “Mistress Y,” who had an alleged sex-for-cash arrangement with the 87-year-old Chakalos shortly before his death.


Carman’s attorneys have said in court papers that the woman, 25 at the time of the alleged tryst, and her drug-addled boyfriend may have been responsible for Chakalos’s murder. In addition to the Rhode Island suit, Carman also faces civil litigation in New Hampshire brought by his aunts, who are seeking to block him from collecting any funds from Chakalos’s estate.
