Sheila Russo, 47, was killed on February 20, 2014, in Alturas, California, during a shooting at the Cedarville Rancheria Tribal Office. Russo was the Tribal Administrator and was attending an eviction appeal hearing when the former Tribal Chairwoman, Cherie Lash Rhoades, opened fire. Sheila was one of four people killed that day; three others who died were Rurik Davis, Angel Penn, and Glenn Calonico. Two additional people were wounded at the hearing.

The attack was tied to disputes over tribal finances. Russo had been investigating apparent misuse of federal grants and had uncovered significant misuse of tribal funds by Rhoades and associates. Prosecutors said the motive stemmed from those financial improprieties and efforts to intimidate or silence others. Rhoades was arrested and later charged with multiple counts of murder and attempted murder; her trial included survivor testimony and video evidence. In 2017 Rhoades was sentenced to death.
