They knew rachael that friday meeting with asoti county sheriffs captain dan hally about the stalking incidents. Detectives c cell phone activity since a voice mail rachael left at 8 09 friday night. That meant rachael had been of the grid nearly three days. I knew there was something very, very wrong. Reporter youd swung into action . I had about a thousand flye printed at staples. Reporter monday afternoon Law Enforcement pinged rachaels cell phone and got a weak echo just across the snake river fr her home. We got a lot of people out into that field that night. Also used a bloodhound to do a live search. We were looking in trash ba and tarps and under bushes. We searched all night. By the time i got home my knee were bloody and my hands. Reporter the search was futile. Early the next day, tuesday, captain hally formed a regiona missing person task force. So whats on your white board . Whats on your agenda . William slemp. Reporter the former boyfriend. Other exboyfriends, exhusbands. Fam there had been a neighbor that lived across the street from rachael that had some suspicious behaviors. Hed ask rachael out on a date and shed turned him down. And then he left town very abruptly. I mean thats certainly suspect. Is he involved . Were c travel information. We checked every bus ticket th was sold that weekend. Reporter an early lead may have come when rachael talked sheriffs captain dan hally th week before. She told him that day she was terrified of the slemp guy messing with her, but the captain had a different stalki suspect in mind after rachael told him she was divorcing charles. So an early stop for investigators was charles sho so whos the guy you met . Easy going, you know, he wa very cordial. Hes being cooperative. I didnt have anything to hide. What was i g here he comes, driving up. Come on in. Reporter charles assured police he had nothing to do wi the stalking or damaging of he car. Youre not vandalizing the vehicle, youre in the scary walking her house . Absolutely not. Reporter did you slash her tires . Absolutely not. Reporter he told the cops was helping rachael get to the bottom of the harassment. He said the estranged couple together went out looking for the obsessed exboyfriend to sort him out. She tells me about him and go driving over to his house because theres a pay phone right near his house thats one of the pay phones that was making phone calls to her. Reporter you thought slemp was the stalker . I thought he was still involved with her because he h this huge crush on rachael. He tells me he was being a helpful guy and trying to help her figure out who is stalking her. Reporter charles went on t tell investigators he hadnt seen rachael since friday nigh when she stopped by to pick up her car. It wasnt ready. He describe how she was upset because hes working on her car. Reporter cha rachael then left to buy a computer. She couldnt find what she wanted, but returned with a six pack. They drank a o and she left. Whats the picture coming together for you . Im trying to keep all options open. Because i was concerned that s might have been impaired and driven off the road. Reporter a benign explanation to why shes gone missing. Right. Reporter but that theory later was doused when they found her suv at a store that doubled as a bus station not far from her house the vehicle was left unlock with her purse in plain sight with the keys in plain sight. Reporter what woman leaves her purse behind . It was a bad sign. Reporter and the detective had to consider another scenario. Had pretty 54 rachael 120 pounds soaking wet offered an easy target for an abduction b a straepger unknown . While detectives wer their official thing, rachaels loved ones were widening their increasingly desperate search all across the palouse. We were putting up flyers from here to colfax, east, wes north, south, we were out ever available minute. Reporter it was as though the palouse had just swallowed her up. Coming up finally a break, police learn there was somebody else with Charles Capone the night racha disappeared, but something doesnt add up. He provided a timeline for that evening, and it was different than Charles Capone timeline. When dateline continues. Reporter Rachael Anderson, mother of four, had vanished, and it was the job of captain dan hally and the missing Persons Task Force to find out what had happened to her. Rachael has not hopped a bus. No. Reporter shes not in anybodys emergency room . No. Thats correct. Reporter you suspect foul play. Light. Absolutely. Reporter the investigators working their way through a li men who wanted to be in rachaels life. There was the neighbor who tri to take her out and been turne down. He had an alibi. That left the old boyfriend named slemp, the one rachael said she was afraid of, but he could account for his whereabouts when rachael went missing. The former boyfriend was not playing out . Correct, yeah. Reporter you had to follow all those leads . Absolutely. As these threads started, we would follow them as we could, but Charles Capone was the one that never was a dead end. Reporter captain dan hally had been suspicious of charles ever since rachael stopped by make a stalking complaint abou the exboyfriend, but that sam day rachael had also told the captain she was in the midst o divorcing Charles Capone. The grounds . She said he tried to choke her. That was a huge red flag. Captain hally advised her to get a restraining order right away against her estranged husband. Rachael didnt want to hear that. She was agitated because i telling her that your soon to ex charles is doing this, not slemp. Reporter two days later th friday she vanished, the captains phone ra she called me and she told that she was going to see charles that night, she was going out to tell him that the were done. Reporter what did you tell her . I told her dont go. I said hes dangerous. Do not go up there. Reporter charles account that night was looking sketchy. The cops suspicions grew afte charles decided to stop cooperating. They suggest maybe you should downtown. Have a more formal conversation. On the 21st, thats correct. You don i talked to my attorney. He said have them contact me if they have any more questions. You dont havee. Reporter the car mechanic had a secret he knew the polic would uncover. It turned out that the publicl pious, prayoverhispancakes christian had a past that rachael and her family knew nothing about. A back story that included prison time for bank robbery a assault. But the onetime felon had apparently changed. Im going and doing everything that a normal perso does because i always feel lik okay, i paid my debt, let me g and move on and do something good and constructive. Reporter youre paying you taxes, mowing the lawn. Nice to be able to walk around with your head up. Reporter the cops werent sure and were now chasing down his friends, including his goo pal, david stone, a married hi School Baseball coach and employee at the moscow idaho maintenance department. To astonishment david volunteered that hed been hanging out wit charles and rachael at the garage the friday night she we missing. Thats absolutely reporter you got another g somebody with information. Immediately raises the questio why didnt Charles Capone ever mention david stone to me duri the entire time i interviewed him . Reporter three days after rachael was reported missing, the Task Force Detectives sat david stone down and grilled him. He provided a timeline for that evening, and it was different than Charles Capone timeline. Reporter the husbands friend told the cops rachael came by the shop about 5 00 p. And waited for charles to finish her car. David stone says he then left get some food at an a w and when he got back to the garage around 8 00, rachael was gone. Stone said he drove charles to local bar, swung by his home for a while, then went out lat to pick up many of the investigators knew david stone and his wife alisa. She worked in Moscow City Hall as a grants writer. Who was your dave, personality, charact . Someone that was very carin was a really good stepdad, wa on the volunteer fire department. Reporter Charles Capone, were they friends . Yes. Reporter did you know rachael . I now her only from church. Repor husband was at the garage that friday night and said nothing seemed amiss. What did he say was going on . He dropped charles off at mingles and there had been som interaction with rachael that wasnt happy and charles said wanted to have a drink and he dropped him off and he was goi to go back and pick him up and hed be home. Reporter intriguing perhap but the two friends mismatche stories did nothing to advance the cops case. With rachael still missing, there was no evidence an actua crime had even occurred. All they had were their suspicions about david stone and Charles Capone. So now you got two different versions. Two different versions. They were supposedly together but theyre telling two different stories. Reporter tangled somewhere in the differing accounts, the cops thought, there must be a buried clue about what had happened to rachael. Meantime, her heartbroken daughters did what they could fill the awful hours. Organizing searches, building web page and pressuring the police. We searched ditches, we searched, gosh, abandoned buildings, we searched yeah we put flyers in towns so that somebody would see her passing through. Their mom meant so much to them. And they did not want this to just become another cold case. Reporter the investigation was heading that way until the detectives revisited an early lead. A nefarious scheme, if true, hard to believe that something as evil as that could happen i the palouse. This is a very tantalizing thread that comes together. This is stuff of the movies . Absolutely.
