to wonder. after all, jr had backed dave in the custody dispute with linda. could dave be covering for him now? for that matter, where was dave the night linda disappeared? >> from what time to what time were you home? >> sunday i was here all day long. >> and you never left your daughter or your other daughter? you just took care of them all day on all night? >> yeah. >> the detective also interviewed rosemary, dave's wife. >> i have a karaoke dj business. and sunday night, i was working. >> dave, she, said was home with the kids. >> so you got home about one or 1:30 and he was home? >> yes he was sound asleep. >> so both dave's wife and gianna's girlfriend said the two men were at their own homes the night that linda disappeared. and despite all that blood, there was still no conclusive proof that linda was even dead. >> we have no body, we have no evidence of anything outside of the entryway.
watson disappeared, at last, here was proof she was no longer alive. >> that's when you have a case. >> that's when i have a case. >> indeed he did have a case. three of them, in fact. detective anderson took over his lead detective after linda's skull was identified. >> by the time i got the case in 2011, it was 11 years old. there is 11 years of investigative work that had been done. i had to start piecing it together. >> it took him a year just to read through it all. there were so many things that stood out, but one in particular caught his eye. it happened years before linda's remains reidentify. >> it wasn't a hot moment for me. >> back in 2007 when detectives punted that new story about the case heating up, we also put a gps tracker on dates vehicle. >> i discovered gps coordinates that indicated on december 31st 2007, he drove his truck and
the broken coffee cup. and some property that linda has left behind, that maybe a little bit suspicious. >> linda's bible was on the counter-, her jeep in the driveway. and perhaps most telling, her pager was left behind. remember, this was the year 2000. >> when she didn't have her daughter, she would keep her pager so that if anything happened with her daughter, that was the way to communicate with her. >> it was important, that's a link to the daughter. >> that's a link to the daughter? >> doesn't mean anything's happened yet though. >> not yet. her purse is gone. so the deputy tells miss cox, let's just wait. >> marilyn did not want to wait. she called her younger sister, pat. >> she tells me pat, linda is missing. of course, you know, this doesn't happen to your family. it happens other people. >> marilyn also called linda's ex husband, dave. >> maryland says that linda's not home, she's missing. she sounded panicked. and i was like, give it some time. it's monday morning. maybe she went somewhere?
or a slip updates tongue that indicated something was sinister. the mystery of linda's disappearance and maryland and the nays murders, no closer to being salt. no way of knowing that out there and the desert, the answer had already been found. coming up, >> it wasn't aha moment for me. >> somewhat like a horse right out of the middle of nowhere. what was he looking for? >> i think he was going back to the scene to see if we were there. if we've been poking around. this is very coincidental that he would write it there when at that point in time, no one else knew. >> when dateline continues. when dateline continues because knowing that your chronic kidney disease in type 2 diabetes could progress to dialysis is important. b is for belief that there may be more you can do. just remember that k is for kidneys and kerendia. for adults living with ckd in type 2 diabetes, kerendia is proven to reduce the risk of kidney failure, which can lead to dialysis. kerendia is a once-daily tablet
>> she is flat out told me as soon as she finds linda, gets jordan. she's leaving this god forsaken place. >> amidst their legal dispute, dave and roseberry glued their family. in 2001, they had a little boy. and then, a year later, rosemary took a bold step and adopted jordan. >> i sent out birth announcements. it's a girl. three foot two. 68 pounds kind of thing. i was ecstatic. >> for jordan, the feeling was much more muted. >> it seemed like what my father wanted to happen. i didn't want to displease anybody. so i just said yes. >> with three kids, the court battle and work, the watson's had their hands full. but they've always made it a point to check in with jordan. >> when i was little, and even now, when you go to work.
into the backyard. and then i saw him. >> where was he? >> he was standing at the back of his deep. i could see him through our kitchen window. he appeared to be, he looked as though he was just cleaning out the back of his deep. >> and then he comes? and >> he does come in. and he said i want for a walk. and i asked him if he was okay. and he said yeah, i just need to clear my head. >> does that make sense to you? >> it didn't make sense to me. ida had no reason to doubt him at all. none. >> and then, rosemary said, dave handed her something. >> he actually handed me a box of latex gloves. and said, put these away. which, you know, i didn't think anything of it at the moment. >> this is your new husband, you're in love with? >> absolutely. >> you don't know all his habits? >> no. still learning. >> and wake up and talk to the birds? you don't know right? >> he was an early riser. >> so when investigators showed up and asked where dave had been the night that linda disappeared. >> i didn't mean to lie. that wasn't my intent.
between linda and dave. >> rosemary also had a daughter from another relationship. and in june of 2000, she and dave took the big step of blending their families. >> had my daughters by my side, he had his two good buddies and we took our vows and celebrated with everyone around us. >> linda also seemed to find happiness in a new relationship. his name was carl broughton jr.. though most people knew him as jr. he was a firefighter to, for the international guard in tucson. >> what do you think? >> he seemed nice. i met him a handful of times. but more than skin deep i did not know much about him. >> linda called marvell and gust about her new flame. >> he was older and i remember her commenting about how he was sexy or something like that. >> she was busy juggling family and career but didn't pay much
when jr and her had no more contact with each other. and she totally focused on dave. >> detectives knew that the whole time knew, that she had been feuding with dave and rosemary over visitation with jordan. pat said the reason that marilyn asked her friend renee with her to drop jordan off. is that she filled a confrontation with dave. >> she felt there was safety in number. >> she recalls an earlier issue when she was on the phone with marilyn, and dave showed up unannounced at her house. >> she let him in the house. which just blew me away. but she wanted him to feel better. having jordan over there. so he could say, this is nice. not dangerous. i'm not planning on taking off. >> but pat said, the visit turned tense. >> she showed him, through the house and took him towards a little bedroom that is just off to the left there. and she said, that's a gun laying there. i won't be as easily taken as linda was. >> marilyn warned everyone around her, that if anything
others dead. that linda was a heavy drinker. >> we had a seriously rocky relationship for over two years. all about all of our problems, revolved right to her alcoholism. >> the drinking was why, jr said, he recently broke up with her. >> she wigs out bad. and things are right now rougher than i've ever seen for her. she just lost her job. >> he said too much alcohol cost linda her job. and jr said, she faced a bigger loss. >> she's looking at losing her daughter. >> turns out, linda and dave had not yet come to terms on custody of jordan. and they had an important court hearing coming up. >> are you going for full custody? >> i did. one, to take the rights away from linda. by no means. because every child needs both parents. >> but after the break up with linda, jr did something unexpected. he agreed to testify on the cause of the hearing on dave's
keep linda's case alive was gone. for a family friend, mark, now the heartbreak was twofold. >> i didn't realize until then that i had never truly let go of the idea of linda coming back until they were killed. and that's when i, realize she is gone. she is dead. >> so this is a double migraine? >> yeah. >> had you agreed to take jody home for the drop off. you would've been in this. >> most likely, yeah. >> three years after linda's disappearance, investigators had a whole new deadly mystery. and the key to unlocking it, just might be a voice from the grave. coming up! >> she let him in the house, which just blew me away. >> did marilyn know what was coming? >> she took him towards a little bedroom and said that's a gun laying right there i will be taking this with us. >> when dateline continues! n dateline continues there's nothing like hitting the waves.
