The New Hampshire attorney general's office says a woman was killed by a single gunshot to the head and the man found dead in the same Exeter house committed suicide.
Dr. Thomas Andrew - the state's chief medical examiner - says the death of 43-year-old Jennifer Noll was a homicide.
Andrew also said after the autopsies Wednesday that 49-year-old Richard Sanderson committed suicide by firing a single shot into his mouth.
Exeter police say they responded to a home on Tuesday for a welfare check and found the couple dead.
The investigation is ongoing.
