Federal investigators unable to crack a two-decade cold case involving the murder of Seattle federal prosecutor have upped the reward to $2.5 million.
Thomas Wales, 49, was shot through the basement window of his Queen Anne home on October 11, 2001 by an unidentified shooter.
The reward was upgraded from the previous amount of $1.5 million after 20 years was considered 'too long' without any solid information on the murder or the parties responsible.
The announcement to increase the reward was made at the 20th anniversary ceremony at the Tom Wales park, named in his honor, where a Japanese maple tree was planted.

Nicholas Brown, the U.S. attorney for the Western District of Washington, announced the new reward at the ceremony with $2 million being offered from the Justice Department and the additional $500,000 from the National Association of Former U.S. Attorneys.
'Twenty years is far too long for this crime — this attack on the American justice system — to go unresolved,' Brown said at the ceremony, according to Fox 13.
Brown is the sixth attorney on the case and believes that 'fresh eyes' on the case might help with the investigation.
The Department of Justice also released a statement on the anniversary of Wales' death.

The most prominent theory surrounding Wales' murder was a revenge hit from a pilot who Wales had prosecuted in a case after he and has business partners had allegedly forged documents and violated FAA safety rules to
