Two men are behind bars in Latah County accused of the 2010 murder of Rachael Anderson as the search continues for the victim's body.
Anderson, 40, disappeared in April 2010. Her body has never been found. Her estranged husband Charles Capone and his friend David Stone have been charged with her death.
Prosecutors say the investigation took a turn when Capone told other inmates while he was in custody that police would never find Anderson's body.
"If it takes a reward to have someone come forward that's what we're going to do," Amber Griswold said, Anderson's daughter, said.
Anderson was last seen at Capone's auto shop. She had planned to tell Capone she was following through with getting a divorce. On April 16, 2010 she went missing, leaving her two daughters pleading for her safe return.
"Keep your eye out, keep spreading the word, and if anybody has seen her or the vehicle over the weekend we want it reported to the police," Griswold said at the time of her mom's disappearance.
Detectives found the SUV Anderson had been driving and her cell phone soon after near Lewiston. Police later arrested Capone on an assault charge stemming from an incident with Anderson in Dec. 2009 but couldn't find enough to charge him with murder.
And then Capone started talking to other inmates in jail. Court documents show Capone told them police would never find Rachael's body, and he also detailed to fellow inmates how he would dispose of a body.
"We're filing at the culmination of three years of investigation, three years info gathering, that put us in the position where we thought we have sufficient basis to proceed and it was time to move forward and try to get some closure and accountability," Latah County Prosecutor Bill Thompson said.
Investigators say Capone and Stone plotted to kill each others wives at one point; now they both face first degree murder charges for the death of Capone's wife.
Prosecutors say they have extensive evidence against Capone and Stone including DNA belonging to both Anderson and Capone found on a piece of a latex glove in the SUV Anderson had been driving.
Capone and Stone will make their next court appearance next Thursday.
As for the search for Rachael Anderson's remains, investigators say finding her is the most important goal they have right now.
