(Seattle, WA) -- Federal authorities are increasing the reward for information on the 2001 murder of federal prosecutor Thomas Wales in Seattle. The reward being upped by $1,000,000 for a total reward of $2.5 million. The FBI is currently pursuing new evidence that a commercial airline pilot who has been the longtime suspect in Wales' death enlisted the help of a drug cartel to carry out his murder.

Investigators believe the cartel then recruited a low-level career criminal from Snohomish County to pull the trigger. They speculate that the pilot was angry with Wales for indicting him and his business partners on charges of fraud for the alteration of a military helicopter for civilian use.
