Glenn Calonicco, 30, was one of four people killed during a violent outbreak at the Cedarville Rancheria tribal headquarters on February 20, 2014, in Alturas, California. The meeting that turned deadly concerned the eviction of former tribe chairwoman Cherie Lash Rhoades and her son from tribal land. Reports say Rhoades opened fire with two semi-automatic pistols, then used a butcher knife after running out of bullets; two others were wounded and one woman escaped to alert authorities.

Victims named include Rurik Davis, Angel Penn, Glenn Calonicco, and tribal administrator Shelia Lynn Russo. Rhoades was arrested and booked on multiple charges including homicide, attempted murder, child endangerment, and brandishing a weapon. The account links the attack to the eviction proceedings and pressure from Rhoades’ brother, who had become tribal chairman.
