CHESTERFIELD, N.H. (AP) — The FBI and other agencies have been at an abandoned New Hampshire property owned by the family of a man whose 2013 homicide remains unsolved and whose daughter is presumed dead after her boat sank during a mother-son fishing trip this year.

The Spofford property was owned by John Chakalos, found fatally shot at his Connecticut home. His grandson, Nathan Carman, was at one time a suspect. No arrests have been made.

Carman accompanied his mother on the fishing trip and says he doesn’t know what happened to her as their boat sank.

An FBI spokeswoman said Friday its evidence response team was assisting a multiagency investigation. A family spokeswoman had no comment.

The Keene Sentinel report at least a dozen people in “hazmat-style suits” were on the property Thursday.
