ALTURAS, Calif. — Police say a woman who opened fire at the headquarters of a Northern California Indian tribe shot and killed her brother, nephew and niece.

Modoc County Sheriff Mike Poindexter on Friday identified the four people who died in the shooting.

He said they included the suspect's brother, 50-year-old Rurik Davis, her niece, 19-year-old Angel Penn and her nephew, 30-year-old Glenn Calonicco. A 45-year-old woman who died wasn't named in this morning's update from the Associated Press.

Police say Cherie Lash Rhoades, former chairwoman of the Cedarville Rancheria tribe, shot and killed the four people on Thursday during a meeting at tribal headquarters about evicting her and her son from tribal land. The headquarters — a ranch-style building with a pitched brown metal roof — is in a residential area about a block from the police station. A handful of sheriff's deputies and police officers were standing outside early Friday.

The area was cordoned off with yellow police tape, and a light powered by a generator illuminated the building.

Alturas Police Chief Ken Barnes said that when officers arrived after the attack, Rhoades was outside the building, running and clutching a knife. A Rancheria employee helped tackle her and she was quickly subdued and brought into custody.

The stabbing victim and one of the shooting victims — both women — were taken to a Redding hospital where they were in critical condition, The Record Searchlight of Redding reported.

Investigators said they found two guns but Barnes said he didn't know whether both had been used in the shooting, according to the paper.

Alturas, the seat of Modoc County, is about 55 miles south of the Oregon border and 35 miles west of the Nevada line.

The Cedarville Rancheria is a federally recognized tribe with 35 members, according to its website. The Rancheria owns 26 acres in Cedarville, where many of its families reside.
