Nicholas Caples was 18 when he was shot and killed inside his family’s home in the Centennial Hills area of northwest Las Vegas on the afternoon of Friday, March 17, 2017. Officers responded to the 10200 block of Yarmouth Sea Court near Farm Road and North Hualapai Way around 3 p.m.; Caples was taken to UMC Trauma and died of a gunshot wound to the chest. School records show he had most recently attended Arbor View High School.

Investigators say the shot was fired by Caples’ 22-year-old brother during a domestic confrontation in which police reported Caples had a knife. Dispatch notes included an account that the older brother fired while the younger brother was trying to stab his mother, and detectives examined whether the shooting might be self-defense. The case was forwarded to the Clark County district attorney for review and no charging decision had been announced as of the late-March 2017 updates.

If anyone witnessed the incident at the Yarmouth Sea Court address or has additional information about that afternoon, please share what is known.
