Thomas Crane Wales (June 23, 1952 – October 12, 2001) was an American federal prosecutor and gun control advocate who was the victim of an unsolved murder.

Soon after, Wales became involved in Washington CeaseFire, most visibly as a vocal supporter of an unsuccessful 1997 state referendum that would have required gun owners to use trigger locks.

[2][1] On the evening of Thursday, October 11, 2001, at approximately 10:40 p.m., Wales was sitting at a computer in his office in the basement of his home at 108 Hayes Street.

[4][5] A gunman avoided the security lights in Wales' backyard and shot him once in the neck and once in the chest through a window, using a Makarov pistol fitted with an aftermarket barrel.

Kimball failed a lie detector test administered afterwards, and agents suspected he had fabricated the account even as he continued to insist he had not.

[15] In February 2018, an FBI official reported the investigation had found "evidence strongly suggesting" Wales was murdered by a contract killer and, for the first time, indicated that his death was likely a conspiracy involving a small group of people.

[11] The United States Department of Justice, meanwhile, announced that then-Deputy Attorney General Rod Rosenstein would arrive in Seattle on Wednesday, February 21, 2018, to brief media on the progress of the 16-year-old investigation.
