Barbara Lewis' death was ruled a homicide after a March 18 autopsy, conducted by New Hampshire's chief medical examiner Thomas Andrew, revealed multiple gunshot wounds to her head and chest.
Elliott Lewis' death, the result of a single gunshot to the head, was deemed a suicide.
A handgun found at the condominium is assumed to be the weapon involved in the crime, assistant attorney general Peter Hinckley said in an interview with The Dartmouth.
"Domestic violence is not a suspected motive in this case," Hinckley said. "There was a lengthy suicide note that was left apparently by the husband."
A press release issued by the Lewis family states that Elliott Lewis' actions were motivated by his deteriorating health and his wife's anxiety about potentially being left alone after his death.
Kirsten Wilson, who until recently was the senior assistant attorney general, said on March 20 that she could not comment on whether the financial and health records of Elliott and Barbara Lewis had been subpoenaed because the case is ongoing. Wilson, who, according to her voice mail, no longer works with the office of the attorney general, could not be reached for further comment after that date.
Elliott and Barbara Lewis "had mentioned in passing that they could not imagine life without each other," the press release issued by the family said.
Hinckley said he believes Elliott Lewis wrote the suicide note, which was addressed to his family. The note's contents will not be made public until the investigation is closed, he said.
Police first responded to the Lewis' apartment at 85 South Main St., which is adjacent to CVS, after the couple's son, Spencer Lewis, found a note taped to the door instructing the reader to call the police but not to enter.
The State Police Major Crime Unit has been working in conjunction with the Hanover Police Department to investigate since approximately 10 p.m. that night. The crime scene unit arrived at the apartment around 1 a.m. on the night of the incident, according to the lead investigator, trooper John Encarnacao of the Major Crime Unit.
The investigation is still ongoing, Hinckley said.
"At this point, we still have things that have to be examined by the forensic laboratory here in Concord," Encarnacao said. "It's a standard practice that we don't make any kind of announcements or statements until all the evidence is looked at. Even though nothing is actively occurring at the scene, that doesn't necessarily mean that nothing is being done."
Encarnacao said he could not comment on the specific items that were seized for processing by the forensics lab.
"We do a thorough investigation of any crime to make sure things are as they appear," Hinckley said. "That's why we are continuing the investigation."
Officials said that they could not estimate when the case will be officially closed.
"It's hard to say," Wilson said. "Things are going pretty smoothly, but to put a time frame on it is unrealistic."
Encarnacao said he believes that the case will be closed "sooner [rather] than later."
Bob Haynes of R.E. Haynes Company, who leased Elliott Lewis the office he used for his financial consulting business, said he was surprised and saddened to hear of the events.
"[Elliott Lewis] seemed like a very pleasant guy, and I'm very upset by this," Haynes said.
Hanover Police Chief Nick Giaccone did not respond for comment by press time.
