Civil rights groups call for new inquiry in to Santa Ana office bombing that killed Palestinian-American

Civil rights groups and members of Congress are pressing the US Justice Department (DOJ) to renew its investigation of a 1985 office bombing that killed Palestinian-American civil rights leader Alex Odeh and injured seven people.

The American-Arab Anti-Discrimination Committee, the National Association for the Advancement of Coloured People, Jewish Voice for Peace and others have launched a petition campaign asking Justice to further investigate the explosion, which demolished the committee’s office in Santa Ana, California. The online petition has about 10,000 signatures.

California Democratic Representative Loretta Sanchez sent a letter to the department in June and is seeking other lawmakers to sign a letter to Attorney General Eric Holder. The FBI identified suspects after the attack, but none were ever named or indicted.

“Whenever a leader for a civil rights organisation is killed, it is the responsibility of our country as a whole – and a civil rights community as a whole – to stand up and demand that their killers be brought to justice and to insure that the US Department of Justice does everything in its power to close the case,” NAACP President Ben Jealous told reporters on Monday.

The DOJ, which has furloughed workers due to the government shutdown, had no immediate comment on Monday, which also was the federal Columbus Day holiday.

In 2010, the FBI described the killing of Odeh in an agency news blog as “an active, ongoing priority investigation” and noted a $1m reward.

Representative John Conyers, said that he wants the House Subcommittee on Crime, Terrorism, Homeland Security, and Investigations to convene a hearing on the bombing.

“We’re going to pursue it vigorously and we’re not going to let any more time lapse,” Mr Conyers said. “We’re going to continue to help all of the organisations that are involved build up more and more support for us getting to where we ought to be in terms of a horrific, violent crime that has – I think – been put on the back burner for far too long.”

At the time of the attack, the FBI said they believed the bombing was the responsibility of the militant Jewish Defence League. An attorney for the group denied the allegations and asked for a retraction from the agency. The FBI also linked Odeh’s killing to two other acts of domestic terrorism in Brentwood, New York and Paterson, New Jersey, that same year.

Odeh, the West Coast regional director for the American-Arab Anti-Discrimination Committee, was killed as he opened the door to his office on 11 October, 1985.

The bombing occurred the morning after Odeh said on a Los Angeles television news broadcast that Palestine Liberation Organisation leader Yassir Arafat was a “man of peace” because of his role in securing the release of passengers from the hijacked Italian cruise ship Achille Lauro in Egypt.

Odeh, who came to the US from Palestine, was described by both Jews and Arabs as a non-violent man who advocated compromise. According to the American-Arab committee, Odeh immigrated to the United States in 1972 and became a US citizen in 1977. He was a poet and lecturer.
