Patricia Candace Walsh, 24, of Seattle was murdered after a cross-country missionary journey with her husband, 25-year-old Douglas Scott Zyskowski. The couple left Seattle in November 1989 to attend a religious convention in Georgia and hitchhiked as they traveled, last contacting friends and family in January 1990 from El Paso, Texas.

Investigators believe the pair accepted a ride near El Paso from long-haul truck driver Robert Ben Rhoades. Douglas Zyskowski’s body was found January 21, 1990, along Interstate 10 in Sutton County, Texas. Patricia Walsh was reportedly held captive for more than a week, raped and tortured in the truck, then shot four times in the head and neck with a .22 caliber rifle; her remains were recovered October 26, 1990, in a remote area of Millard County, Utah and not identified until 2003 through dental records and DNA.

Rhoades, already serving a life sentence in Illinois for another murder, has been linked to these killings; he was extradited to Utah in 2005 and later moved to Texas so prosecutors could try him for both deaths. Does anyone have information about the couple’s route or sightings along Interstate 10 in January 1990?
