New Push for Help

in Solving a Prosecutor’s 2001 Murder


September 28, 2011

The New York Times



SEATTLE — Ten years after a federal prosecutor here was shot to death while sitting at a computer in his basement, Attorney General Eric H. Holder Jr. and other federal law enforcement officials announced a new effort on Wednesday to seek public help in the investigation through a multimedia advertising campaign.

The prosecutor, Thomas C. Wales, 49, was killed late on the night of Oct. 11, 2001, by a gunman who investigators said stood in Mr. Wales’s backyard in the Queen Anne neighborhood of Seattle and fired through a window.

Law enforcement officials say they have investigated several suspects, pursued more than 15,000 leads and meticulously traced and tested copies of a rare type of gun barrel used in the shooting. But they still have not solved the crime. A $1 million reward remains in place.

Investigators have not publicly identified a motive for the killing. If Mr. Wales, who was an assistant United States attorney, was killed in retaliation for his work, he would be the first federal prosecutor killed in the line of duty. He also was president of a group that campaigned against gun violence.

“Although this case remains unsolved and Tom’s killer remains unknown, our resolve to uncover the truth and to help Tom’s family, friends and colleagues and neighbors find the answers and find the closure that they deserve, that has never been stronger,” Mr. Holder said.

Officials also sought the public’s help around the time of the fifth anniversary of the killing in 2006. This time, the government is placing newspaper, radio, television and Internet advertisements as well as buying space on billboards. A special Web site was to go up late Wednesday.

“This is still not a cold case,” Greg Fowler, the special agent in charge of the F.B.I.’s office in Portland, Ore., said in an interview on Wednesday.

“The case team works every day on this,” said Mr. Fowler, who is now overseeing the inquiry. “It’s their full-time job.”

He said that “some investigative considerations, which I’m not prepared to discuss,” played a role in the new public push for information, “but for the most part it’s timed to the anniversary.”

“Hopefully, this will stir something in people’s minds or spark a memory,” he said.

For years, a principal suspect in the case was a commercial airline pilot who was among four people Mr. Wales indicted on conspiracy and fraud charges in 2000. The next year, the government dismissed that case after the defendants pleaded guilty to charges related to the sale of a military helicopter. The pilot sued for legal fees four months before Mr. Wales was killed. The lawsuit was later dismissed.

Mr. Fowler would not say whether the pilot remained under investigation. Larry Setchell, a lawyer for the pilot, would not comment.
