The reward is now $16,000 for information leading to the arrest of a murder suspect in Clackamas County.
The Clackamas County Sheriff's Office and the U.S. Marshals are looking for Dirck White. He's the prime suspect in the murder of Weighmaster Grady Waxenfelter on Feb. 6.
At the time, White was a delivery driver for O'Malley Brothers Trucking in Estacada.
The victim had reportedly stopped White while White was driving a truck hauling wood for not having a license plate on the trailer.
White is also wanted in Pierce County, Wash. on a weapons charge. He is also a suspect and wanted for questioning for a sex crime regarding the rape of a child in Pierce County.
If you see White or the suspect vehicle - a four-door 2004 Mercedes 320 with Washington license plate ANB7070 - call 911 immediately. Do not approach as White is still considered armed and dangerous.
A donation fund has been set up by the Clackamas County Peace Officers Benevolent Foundation. 100 percent of donations will go directly to the Waxenfelter family.
Donations can be made at any Clackamas County Federal Credit Union branch.
