PAPEETE, French Polynesia (AP) _ Marlon Brando's daughter, who fled to the South Pacific after refusing to testify against her brother in the murder of her 26-year-old boyfriend, has been charged with conspiracy in the killing.

The victim, Dag Drollet, was shot to death May 16 at the actor's estate in the Santa Monica mountains near Los Angeles. The actor's son, 32-year-old Christian, is charged with the murder.

Brando's 20-year-old daughter, Tarita Cheyenne, went to French Polynesia after refusing to testify against her brother, according to Deputy District Attorney Steven Barshop of Los Angeles.

It was not immediately clear whether she would be extradited to the United States.

Tarita Cheyenne Brando, a native of these South Pacific islands, is the daughter of Brando and his current wife, Tarita Teriipia, the Tahitian actress who played his love interest in the 1962 remake of ''Mutiny on the Bounty.'' Judge Max Catti on Tuesday accepted the charge of conspiracy against Brando's daughter, acting at the request of a lawyer for the victim's family. She was ordered not to leave French Polynesia.

Barshop, who is prosecuting the case against Christian Brando, told a California judge on June 25 that he would attempt to introduce statements by Miss Brando as evidence against her half-brother in a hearing later this month. He said the statements were made in a June 12 interview with police.

Miss Brando returned to French Polynesia eight months pregnant with the child of her slain boyfriend. She was in a Papeete hospital undergoing treatment for nervous exhaustion.

Her father maintains a home in Tahiti. The actor was home at the time of the slaying, but he was elsewhere in the house and did not see it. His son reportedly told police that Drollet died during a struggle over a gun.

Christian is the son of the actor and his first wife, Anna Kashfi. The couple was divorced in 1960. Their son was the subject of a bitter custody battle.
