The death of an attorney and Republican activist in his New Hampshire home is being investigated as a homicide.

The New Hampshire Attorney General's Office said Sunday that a medical examiner ruled the death of 41-year-old Alexander Talcott a homicide and that he died from a stab wound to the neck, according to a press release.

Talcott was found dead in his Durham home Saturday morning, with police at the time saying they were investigating a suspicious death. Talcott was identified as the victim the next day, while the AG's office press release said they had also identified all the people involved in the incident and were continuing to investigate. As part of that investigation, authorities are attempting to determine whether the person who stabbed Talcott was acting in self-defense, the release said.

The names of the other people involved have yet to be released. The Durham Police Department referred a Fox News request for comment to the New Hampshire Attorney General's office, who referred back to the release.

Talcott was a well-known lawyer and Republican activist, with the state director of the New Hampshire chapter of the Republican National Lawyers Association (RNLA) telling NBC10 Boston he was "a staunch advocate for the core values of the Republican Party."
