Their search started Tuesday, after family members of Susan received an anonymous tip about the farm that was once occupied by an aunt and uncle of Susan’s husband, Josh Powell.
Cox turned the tip over to West Valley City Police who were supervising the search in Central Oregon. City Manager Wayne Pyle said the nature of the tip was credible enough to launch a search.
Investigators are looking in a concentrated, narrow piece of wooded and rough terrain on the farm.
By Wednesday night, the search had been unsuccessful. Pyle was not sure how much longer West Valley City Police Officers would be in Oregon.
“There’s no hard deadline,” Pyle said. “We will follow the terrain and the size of the geography in which we’re looking to whatever end it seems to take us or needs to take us, but it seems at this point it won’t be much longer.”
Pyle said detectives would keep searching for Susan until they have no more credible leads.
Even though hundreds of calls initially poured in, officials said the tips are diminishing -- and with it, the chances of finding Powell.
Susan Powell disappeared from her West Valley City home in December 2009. Her husband, Josh, considered a “person of interest” in her disappearance, killed himself and the couple’s two small boys in a house explosion in Graham, Washington in 2012.
