Wrongfully accused of murder, Federal Way man released

On January 15, 2009, Glenn Proctor of Federal Way was released from jail where he had been held for 11 months awaiting trial on a murder he did not commit. Prosecutor Don Raz dismissed the case against Glenn after defense attorneys Diane Zumwalt and Mark Prothero provided evidence to convince the prosecutor's office they had the wrong man. Zumwalt was appointed to represent Proctor in March and enlisted Prothero in mid-June. They retained a forensic media and technology specialist, Dr. Thomas Sandor, of Renton. Dr. Sandor was able to clarify and enhance surveillance video from the scene of the homicide. By utilizing "relative cranial measurements" Dr. Sandor was able to help establish that Glenn Proctor was not the murderer. For more information about this case, here are some links to the news stories:

Mark was quoted in an article in the Seattle Post-Intelligencer:


"In April 2006, Greg Girard and Mark Prothero were named "2006 Trial Lawyers of the Year" by the Western Washington edition of "Presumed Innocent" magazine.

In May of 2006, Prothero and Girard prevailed in the Washington Supreme Court in the case of State v. Hanson. The court's unanimous 9-0 ruling guarantees expert witnesses at public expense for indigent clients represented by privately-retained or pro bono counsel. The case was consolidated with another defendant, well-represented by Steve Witchley of Ellis, Holmes, and Witchley, PLLC, a Seattle criminal defense firm. Mr. Witchley presented the oral argument and did an excellent job.

STATE OF WASHINGTON v. GARY RIDGWAY
The Defense of the Green River Killer

The Green River murders involved at least 49 victims, young women who had been murdered or had disappeared from 1982 to 1984. My twenty years of experience, especially with death penalty cases and cases involving DNA, put me in the position of co-lead counsel

 

2006-05-31

One after another, the Green River killer admitted he took the lives of more than 70 young women. The hunt for a suspect galvanized the Seattle-Tacoma area for more than 25 years. Finally the killer had a face: Gary Ridgway. The new novel "Defending Gary" describes the search for justice through the eyes of Mark Prothero, Ridgway's defense attorney.
