Chrystal Ann Lewis, 44, was found dead at her home on Pine Park Road in Haverhill, New Hampshire, on the morning of August 15, 2017. Authorities determined she died of a single gunshot wound to the head and the manner of death was ruled a homicide.

A 45-year-old man, Robert Taylor, was also found at the scene. Lewis and Taylor had been in a dating relationship for several years; Lewis had ended the relationship the month before. Investigators from the New Hampshire Attorney General’s Office and the New Hampshire State Police concluded Taylor was the only suspect and that after shooting Lewis he took his own life, leading officials to classify the incident as a murder-suicide and close the investigation.
