SACRAMENTO, Calif., Sept. 11 — Sandra Good, a disciple of mass murderer Charles Manson, says a “People’s Court” has marked for assassination scores of business executives whose firms pollute the environment.

The FBI and local police declined to comment on whether Miss Good’s remarks violated any law. Both the FBI and police said they couldn’t comment because of a gag order imposed in the trial of another Manson family member, Lynnette “Squeaky” Fromme. Miss Fromme, who is Miss Good’s roommate, is charged with attempting to assassinate President Ford.

In Washington, a Justice Department spokesman said attempts against the lives of private individuals normally would be covered by state rather than federal law. He said as a “curbstone opinion” the Civil Rights Act might be involved under a section that pertains to an individual’s right to live.

Meanwhile, a Dow Chemical Co. spokesman disclosed that one of its executives had received a threatening telephone call from a purported Manson family member. The spokesman, who declined to identify the executive, said the caller was a woman.

The FBI in Detroit said it was investigating to determine whether a federal offense was involved in connection with the reported threat to the Dow official because the incident apparently involved a call across state lines.

And California Atty. Gen. Evelle Younger revealed that Manson had threatened four years ago to send “five people to assassinate President Nixon and (then Gov. Ronald) Reagan.’

Reagan said he and his family were placed under heavy guard in his last year as governor because of the threats.

In an interview in her apartment, Miss Good gave The Associated Press a list of about 75 names of persons she said were marked for death. She identified them as executives primarily in the power, lumber, oil, food and chemical industries.

The list did not include the names of six Louisiana, Texas and Georgia businessmen that Miss Good had previously told newsman Bob Ruby of New Orleans radio station WWL would be assassinated.

“Anyone who pollutes the earth, destroys wildlife, or cuts down trees had better stop now or they and their wives will be terribly, terribly murdered,” Miss Good told Ruby by phone. “Assassinations are necessary since people are asking for trouble by hurting the earth and from what they are programming on television.”

Miss Good gave the AP a statement saying, “the International Peoples’ Court of Retribution is a wave of assassins. It is made up of several thousand people throughout the world who love the earth, the children and their own lives. They have been silently watching executives and chairmen of boards — and their wives — of companies and industries that in any way harm the air, water, earth and wildlife.”

She declined to say where the names came from. She said the wives of executives who are marked for death are being watched as they keep social dates.

“They can be assassinated on the golf course,” she said.

Asked who the assassins are, she said “they’re underground.”

Asked who would order the killings, she said, “They move of their own accord — necessity dictates policy.”

At one point she said the people’s court has nothing to do with the Charles Manson family, but at another point she said, “Manson must be given a seat in the United Nations.”

The names on the list ranged from some in Sacramento with home addresses to single entries such as “all automobile companies” and “General Electric nuclear plants.”

In an interview with AP Radio, Miss Good said that executives of any company which destroys the earth, water, trees, air or wildlife are potential targets of assassination.

She said she was “simply warning these executives” that they must stop destroying the earth.

She said executives of “Exxon, ITT, Standard Oil, Union Oil, lumber company executives, Gulf Oil, must get out the country or you’ll be killed … We want to live, you maggots, you monsters. Get out of the country or you’ll be killed.”

The six businessmen Miss Good named in her interview with Ruby were:

Floyd Lewis of New Orleans, president of Middle South Utilities, Inc., which the woman said threatened the people by planning to build nuclear reactors; Gordon Ryan of New Orleans, an attorney and executive with Starr Broadcasting Co.; Fred Kaiser of Atlanta, a candy manufacturer; Herbert Grey of Atlanta; William Berrin of Atlanta; and Richard Davis of Houston, Tex., an oilman.

In Sacramento, Miss Good confirmed that she had talked to Ruby.

She said she would reveal later the names of others in the United States and abroad who have been marked for death.

She told Ruby during a 30-minute telephone conversation that the wives of the six businessmen would be hacked to death first. She said they are guilty of pushing their husbands to continue instead of reconsidering their actions.

Miss Good avoided saying she was personally involved in the plots, but she said she had direct access to information on who would be killed.

She also said Manson’s “family” was deeply involved.

A spokesman for WWL said Miss Good also threatened Ruby’s life but that the threat was edited out of the broadcast tape.

Manson and three of his women followers are serving life prison terms in connection with the 1969 slaying of actress Sharon Tate and six others in California.
