and here, near the tip of its northern arm is, the spider lake resort. family cabins by the day or week. calls itself one of "northern minnesota's best kept secrets." secrets, a word that will certainly apply to what you're about to hear, one way or the other. kay king: i went with them a couple of times up there. keith morrison: them being chris and jan kruse. this is jan's sister, kay. kay king: they would like to go fishing. just stay at a cabin. just relax. it was just quality time together. and they did. they both enjoyed being there. keith morrison: in fact, they had a fantasy, chris and jan, a dream to live here all the time. to buy this resort and make it uniquely their own. that was brought up a lot, yeah. keith morrison: jan's dad terry could see how they loved being here. terry pigman: about every evening, jan and chris would take the boat. and jan liked to take pictures of the loon and the wildlife along the lake and the sunsets off of the lake. that was the kind of life they would have liked. keith morrison: and if they owned it, said jan's

keith morrison: and really, was a resort at spider lake such a huge issue, such a motive? why would you murder someone you were going to start a resort with? now, he's going to start the resort by himself. steven groschen: it never, to me, was a sound motive of what took place. because the reality of it was is he needed jan to run the resort with him. keith morrison: of course, they didn't have to present a possible alternate suspect, but they did. there's another person here that could have done this, and it's jeremy majerus. keith morrison: jeremy majerus, who, by the time of the trial, was still with bailey. was her boyfriend. and yet, the defense went there. said, maybe jeremy did it? why would jeremy want to kill jan? part of the motive would have been bailey leaving town and moving up north for the cabin, and then she would have less interaction with jeremy. and i'll be the first to tell you, do i think it's a strong motive? no, i don't. does it make more sense than chris's? in some ways, it actually does. because i can see him becoming the jealous boyfriend. and he p

keith morrison: jeremy said the arguments, according to bailey, were about trying to buy the spider lake resortison: so bailey was having trouble dealing with all that, said jeremy. keith morrison: was it true, what jeremy was saying? bailey hadn't said anything like that when she talked to investigators a few hours after her mother was killed. so the very next day, they brought bailey in again to ask about her parents. at first, they didn't tell her they'd been talking to jeremy. keith morrison: no disagreements? then they told her about the jeremy interview. keith morrison: and then she painted a slightly different picture of what had been going on at home. things had been difficult lately. there was that upsetting garage fire, but also, jan had a hysterectomy, chris had his appendix out, and then on top of it all, they were trying to figure out the whole resort deal. keith morrison: so once again, they asked bailey, what happened the night her mother was shot? what she heard from her bedroom, one floor below her parents' room? derek woodford: we asked bailey, did you hear anybody running out

and he knew if they bought the spider lake resort, they'd be taking bailey hundreds of miles away from where was he night of the murder? initially, he had told investigators that he did not leave his house that night. keith morrison: but that was a lie. derek woodford: and then, in further talking with jeremy, he had admitted to us that he did leave the house to go check on bailey and was concerned about her. keith morrison: his story? bailey had texted him after she heard those two shots. and there was, indeed, a text. one word, "jeremy." that alarmed him, he said. so he drove to brewster, texting her along the way. asking her what was wrong. but when he arrived, bailey's street was filled with emergency vehicles. so he returned home. keith morrison: kind of something he should have told you right off the bat. yes. and we had-- how did he explain that? what he had indicated to us is that based on everything that had been going on at the kruse residence, his dad had told him that he thought he should stay out of it and not get involved. thus, not telling us that he left to go to brewst
