Charles Capone, 52, is on trial for charges of first degree murder and failure to notify a coroner or law enforcement officer about a death.
Capone is accused of killing his estranged wife, Rachael Anderson, who disappeared in 2010.
Anderson was in the process of filing for divorce when she disappeared.
Her body has never been found, despite multiple searches including in the Snake River near Clarkston.
Capone's trial was scheduled to start June 23rd, however Judge Michael Griffin took himself off the case and the trial was re-scheduled with a new judge.
During opening arguments prosecutors told the jury that Anderson did indeed go missing and that prior to her disappearance, she feared Capone.
Prosecutors called all four of Rachael Anderson's children to the stand.
"I've described it to people as watching like when your parents go through cancer. They are just suffering. She was just suffering and she was just so sad and so upset and so confused," said Rachael Anderson's daughter Amber Griswold.
Also testifying Tuesday were two of Anderson's ex husbands and a sister.
One witness scheduled to testify is David Stone, who's accused of playing a role in Anderson's murder and disappearance.
He pleaded guilty to a lesser charge in exchange for his testimony against Capone.
Testimony will resume Wednesday at 9:00 a.m.
