On November 22, 2014, Angela Adams, 25, was among three people fatally shot in Sisseton, South Dakota. Vernon Renville Jr. and Candice Labelle also died; a fourth victim, Karissa DogEagle, survived with serious injuries. Authorities concluded the deaths and injuries were caused by a single shooter, Colter Arbach, who was found dead at the scene from an apparently self-inflicted gunshot.

The South Dakota Attorney General’s office described the incident as rooted in domestic violence. Angela Adams worked at a local nursing home and hospital and was a mother of three; her family and community were left grieving after the attack.

If anyone knew Angela, her activities that day, or has information about the circumstances leading up to the shooting, please share what you know with investigators.
