Charles Capone, 51, was charged with 2nd-degree assault domestic violence against his estranged wife, who went missing after he allegedly tried to strangle her just before she went missing in 2010.
While the trial, which has been moved to Dayton at the Columbia County Superior Courthouse, is related to the alleged strangulation, Capone is considered to be a person of interest in Anderson's disappearance.
"One of the real downsides to moving the trial from here to Dayton is the witnesses are going to be traveling to Dayton to testify everyday and we'll have to set up some sort of mobile office in Columbia County," said Asotin County Prosecutor Ben Nichols.
Capone is currently being held in the Asotin County Jail on a $1 million bond after pleading not guilty to charges in October. Jury selection for his trial begins on March 23rd in Dayton.
