Judge throws out most of Steven Powell's journal entries in voyeurism trial

Steven Powell sits at the defense table in his voyeurism trial in Pierce County Superior Court in Tacoma.

The judge in Steven Powell's voyeurism trial Tuesday threw out most of Powell's personal journal entries, many of which pertained to his missing daughter-in-law, Susan Cox Powell.

In issuing his ruling, Pierce County Superior Court Judge Ronald Culpepper said he felt the entries were prejudicial because they did not pertain to the alleged victims in this case -- two girls who lived next door to Powell when photos were taken of them.

Culpepper said he would allow one journal entry -- one that describes Powell's alleged voyeurism in more general terms.

Also on Tuesday, jury selection was completed for the trial. Testimony begins Wednesday with the mother of two young girls Powell is accused of taking photos of expected to take the stand.

Other witnesses are expected include Pierce County detectives and Powell's daughter, Jennifer Graves of Utah, who is expected to testify against him. 

Testimony is expected to begin at 10 a.m. 

Susan Cox Powell, who was married to Steven Powell's son, Josh Powell, disappeared in Utah in 2009.

Josh Powell, who police said was a person of interest in his wife's disappearance and who later moved to Washington state with their two sons, killed himself and their two sons earlier this year.

Susan Powell has never been found. Authorities in Utah said the investigation into her disappearance is still ongoing.
