A southwest Washington cancer researcher was sentenced today in U.S. District Court in Tacoma to 18 months in prison, three years of supervised release and $376,679 in restitution for tax evasion, announced U.S. Attorney Jenny A. Durkan. Peter D. Urrea, 74, of Washougal, Washington made a variety of phony documents to avoid paying $376,679 he owed in income taxes for years 2005-2009. At sentencing U.S. District Judge Ronald B. Leighton said, “this crime is unique because of its depth, and the tenacity and persistence” involved.
