ALTURAS, Calif. (AP) -- The woman who police say killed three family members and a worker at the headquarters building for an Indian tribe that was evicting her and her son from its land was the target of a federal investigation into at least $50,000 in missing tribal funds.
Investigators have been looking into whether Cherie Lash Rhoades took federal grant money meant for the Cedarville Rancheria tribe she once led, a person familiar with the tribe's situation told The Associated Press on Friday. The person spoke only on condition of anonymity.
Rhoades recently was ousted as chairwoman of the 35-member tribe that includes many of her relatives.
On Thursday afternoon, her brother, Rurik Davis, and other tribal members were attending a meeting involving Rhoades's potential eviction at the headquarters building in the rural northeastern California community of Alturas. It's unclear precisely when the shooting began, but in quick succession Davis, 50; Rhoades' niece, Angel Penn, 19; her nephew, Glenn Calonicco, 30; and Shelia Lynn Russo, 47, were killed.
Investigators were looking into whether the embezzlement allegations spurred the tribe's efforts to evict Rhoades, but had not established any definitive motive, Alturas Police Chief Ken Barnes said Friday.
"If we could confirm or deny that, it would help me toward a motive," Barnes said.
Later Friday, police armed with rifles and pistols searched her home. One Alturas police officer who would not give his name acknowledged that they were serving a search warrant, but would not say what they seized.
Eviction from tribal housing is among the most serious punishments for American Indians. One of Rhoades' nephews, Jason Penn, said Davis was behind the effort.
"Her brother drove her too far," Penn said as he stood in the front yard of Rhoades' home on the tribe's land in Cedarville, about 15 miles from Alturas.
Penn said he drove into Alturas on Thursday with Rhoades, and she dropped him off at a cousin's home before going to tribal headquarters. He later heard about the shooting.
"All I heard was there was some shooting, and my sister and brother were dead," he said with a shrug. His sister was Penn, and his brother Calonicco. "I've gotten over worse."
The fourth victim, Russo, 47, was a tribal administrator who managed evictions and had two teenagers, said her mother, Linda Stubblefield of Taft. Davis's two daughters were wounded, police said.
One was alert and talking. The other remained in critical condition, Barnes said.
Barnes said young children were inside the building and on the property, and a judge from another tribe was listening to the eviction proceedings over the phone when the shooting began. After running out of bullets, Rhoades grabbed a kitchen knife and stabbed a woman, police said.
She chased one of Davis' daughters out of the building and into the parking lot while brandishing the knife, Barnes said.
Authorities were alerted to the attack when a woman covered in blood ran to nearby City Hall and rang a bell to get into a side door, City Clerk Cary Baker said.
"She was saying, 'Help me, help me, people have been shot,'" Baker said. The woman was not injured, Baker said.
Officers arriving after the attack found Rhoades outside the building, running and clutching a knife, Barnes said. A tribal employee helped tackle her, and she was quickly subdued and arrested.
Rhoades was booked on suspicion of homicide, attempted murder, child endangerment and brandishing a weapon. Russo's husband works at the jail, so Rhoades was transferred to an undisclosed location, authorities said.
The tribe's headquarters -- a ranch-style building with a pitched brown metal roof -- is in a residential area about a block from the police station. The area was cordoned off with yellow police tape Friday.
In addition to a kitchen knife, investigators found two semi-automatic pistols at the scene.
Alturas, the seat of Modoc County, is about 55 miles south of the Oregon border and 35 miles west of the Nevada line. The motto of the community of 2,800 people -- "Where the West Still Lives" -- reflects the area's wilderness and natural beauty.
The Cedarville Rancheria is a federally recognized tribe. The Rancheria owns 26 acres in Cedarville, where most members reside in nine small, one-story houses on lots on the outskirts of town. The tribal houses are clustered around a small playground.
An audit of the tribe's books by a private firm showed the tribe received $1.1 million in federal money in 2012. About half went toward tribal roads, with the balance directed to governmental and general assistance, and housing.
