Mary began her career as an emergency dispatcher for first responders in two different rural Sheriff’s offices, all while putting herself through college. She graduated with honors from the University of Puget Sound’s law school in Tacoma.
With an interest in public service, Mary joined the Pierce County Prosecutor’s Office in 1994 and worked her way up through the ranks to become the Chief Criminal Deputy Prosecutor. She was called upon to handle some of Pierce County’s biggest cases, obtaining convictions against all four of the 2010 Craigslist murderers who killed Jim Sanders in front of his wife and children, Frank Nordlund (a.k.a the “Parkland Rapist”), and Zina Linnik’s murderer Terapon Adhahn, who is now serving a life sentence in Walla Walla.
Uncomfortable with the partisan, political way current incumbent Mark Lindquist operated, she departed in 2012 to join the state Attorney General’s Office. Hired by Rob McKenna (R) and promoted by Bob Ferguson (D), Robnett works as an assistant attorney general in the Sexually Violent Predators unit keeping high-risk sex offenders away from Washington communities.
Based on her performance and initiative, Mary was awarded the Attorney General’s Excellence Award (2015) and the Attorney General’s Office STAR award (2017).
During her tenure at the Pierce County Prosecutor’s Office, the Pierce County Sheriff’s Office twice awarded Mary the Deputy Prosecuting Attorney of the Year Award, in 2006 and again in 2012. Mary was also awarded the Tacoma Police Department Certificate of Merit in 2009.
Mary believes Pierce County residents deserve better from the Prosecutor’s office. She has management know-how and extensive courtroom experience trying complex cases. Mary can restore trust and run the Prosecutor’s Office in a non-political manner. She is intent on restoring the public’s trust and letting veteran deputy prosecutors do what they do best: Put the bad guys away.
Mary and her husband Bill, a military veteran and retired law enforcement officer, make their home in Tacoma.
