Barricaded Sierra Vista man died from self-inflicted gunshot wound

Christopher Nicolson barricaded himself for more than three hours on Tuesday afternoon before killing himself, according to Sierra Vista Police. Police report that they responded to a domestic violence call and ultimately found that Nicolson, had died from a self-inflicted gunshot wound.

According to Sierra Vista Police (SVPD), “officers responded to the Nicolson residence in the 3300 block of Greenbrier Road in reference to a domestic violence incident at about 12:50 p.m. on Tuesday. Upon arrival, officers made contact with Christopher Nicolson’s father, who was wheelchair bound and attempting to vacate the residence. While assisting the father, officers learned the father and son had an argument, and Christopher threatened his father with a handgun inside the residence and fired a single round, which did not strike either man.

Once the father was removed from the home, “officers set up a perimeter around the house while the SVPD Tactical Unit responded to the scene to assist with the son. Officers also evacuated nearby residences and closed nearby streets.

The SVPD Tactical Unit after three hours “deployed a robot and enlisted the assistance of the Cochise County Sheriff’s Office SWAT Team and an additional robot to enter the residence safely. When the SVPD Tactical Unit entered the residence, officers discovered Nicolson had died from a self-inflicted gunshot wound. It’s unclear exactly when the fatal gunshot was fired,” reports SVPD.

This investigation is ongoing and anyone with information relevant to the case is urged to contact SVPD Detective Thomas Ransford at (520) 452-7500.
