William Welch II supervised the Justice Department’s Washington, D.C.-based public integrity section, an elite unit that handles corruption cases. He was transferred to Massachusetts after the Stevens case unraveled.

Brenda K. Morris was the No. 2 attorney in the public integrity section. She was pulled into the Stevens case after the U.S. senator demanded a speedy trial in an effort to resolve the case before the 2008 election. Morris, a tough trial attorney, was assigned the task of cross-examining Stevens during the trial. She recently has been part of a team prosecuting an alleged scheme in Alabama to influence pro-gambling state legislation.

Nicholas Marsh was a veteran trial attorney in the public integrity section who handled much of the courtroom work in the Stevens trial. He was reassigned to international extraditions after the Stevens case. An FBI whistleblower accused him of intentionally withholding evidence that could have helped Stevens. He hanged himself in September 2010.

Edward Sullivan was a new trial attorney in the public integrity section when he was put on the team prosecuting Alaska political corruption. He had a background role in the Stevens case writing briefs. After the Stevens trial, he was temporarily reassigned with Marsh to international extraditions. He returned last year to the public integrity section.

Joe Bottini was one of two assistant U.S. attorneys in Anchorage who worked on the Alaska political corruption cases while the rest of the office was recused. At the Stevens trial, he had a leading role, questioning the government’s star witness, Bill Allen, and delivering the second half of the government’s closing argument. Bottini, who went to high school in Anchorage and served briefly as acting U.S. attorney for Alaska, remains a federal prosecutor in Anchorage.

James Goeke was the other Anchorage-based assistant U.S. attorney who worked on the corruption cases. He was part of the Stevens trial team, but like Sullivan had more of a behind-the-scenes role. He now is with the U.S. Attorney’s Office for the Eastern District of Washington, based in Yakima.

Mary Beth Kepner was the lead FBI agent in the Alaska corruption investigation. She was accused by FBI whistleblower Chad Joy of having an inappropriate relationship with lead government witness Bill Allen. Her role is still under investigation by the Office of Professional Responsibility, a Justice Department agency that investigates allegations of wrongdoing by federal prosecutors and law enforcement.

U.S. District Judge Emmet Sullivan presided over the Stevens trial. He appointed Henry Schuelke III in April 2009 to investigate whether the six prosecutors who worked on the Stevens case should be charged with criminal contempt for failing to turn over evidence that could have helped the Stevens defense.

Henry F. Schuelke III is a Washington, D.C., attorney and former federal prosecutor. He submitted his 500-page report to the judge in November. That’s the document now being released. Schuelke concluded the evidence didn’t support a contempt prosecution because the judge never ordered the prosecutors to turn over the evidence at issue.

U.S. Sen. Ted Stevens represented Alaska in the Senate for more than 40 years, the longest-serving Republican senator in history. He was in the midst of a re-election bid in 2008 when a jury found him guilty of seven counts of lying on his Senate financial disclosure forms, which prosecutors contended he did to conceal gifts and a home renovation from Bill Allen, then the head of oil field contractor Veco. After prosecutors admitted they had failed to turn over evidence that could have helped the Stevens defense, the guilty verdicts were thrown out. Stevens was killed in a plane crash in 2010.

Bill Allen is the former Veco Corp. chairman who became the government’s star witness in the corruption probe. He pleaded guilty to bribery and conspiracy and served almost two years in federal prison and a halfway house.
