Man quite honestly, is it possible she is alive . Annie he was watching her and following her. Deeply creepy stuff. Criminal acts that hed recorded. Yes. Thats his favorite thing. Collecting women. My heart just sunk. How many other times has he done this . How many other women has he done this to . Narrator a young nurse vanishes in a mystery stained with evil. He brought us to the back. Man and we all looked down. We just gasped. Narrator the front range of colorado, the vast Grasslands East of the Rocky Mountains offers plenty of places to conceal the body of a 97 pound woman. This woman, Tina Sandoval. But the question that gets set for the next two decades. Where are you, tina . And then the searches begin. Yeah. Where are you . Brad goldschmidt yeah. And we searched, oh gosh, probably over 50 different locations. Narrator officially she was a missing person. Had been for more than 20 years. But the authorities, like then detective Brad Goldschmidt, couldnt accept that she was a runaway looking for a fresh start. Hed spent more hours than he could count searching Gravel Pits and Drain Ponds for missing tina. So poor tina was just a small little woman, and theres a lot of colorado. I mean, just this One Area here. Did you think were never going to get this . Oh, i thought we would never get her. Narrator they couldnt prove it, but it was the consensus of Law Enforcement that the young nurse was the victim of foul play. Her Sister Susan didnt disagree. It just wasnt fair. She would have been so good for the world. Narrator and she had an unshakable theory about who made her sister disappear. Evil. Hes just evil. Narrator did you think, i now have Hannibal Lecter here . Yes. This guy is by far the worst criminal ive ever investigated. And thats 21 years of Gang Investigations under my belt. Im certain he committed a felony a day for the majority of his adult life. And he got away with it constantly. Narrator the problem with the missing Tina Investigation was this. How could a prosecutor convince a jury she was murdered if you couldnt even prove Beyond A Reasonable Doubt that she was, in fact, dead . Take it off. What were the usual ingredients you were missing here . We did not have a victims body. We did not have any kind of a Confession Or Admission by a suspect. We didnt have a crime scene. We didnt have any physical evidence. Narrator carol, a Nurse And Coworker of tinas, spent weekends looking for her vanished friend only to be startled awake later with a Stephen King like vision. I would be like on a remote area and she was in a Shallow Grave in my dream. And she would sit up kind of Zombie Style and she was trying to tell me where she was buried. And i always wondered, is that really her telling me . Or is this just my way im coping with this . Narrator eventually there would be a grave, but it wasnt shallow and it wasnt out in the prairie. But theres so much to know before i tell you about that. There you go, big guy. Narrator go back to a time In America when kids would play outside on summer nights till the streetlights came on. In windsor, colorado, you might have met the tournais. There are a lot of them. Heres annie. Annie nine kids. Seven girls, two boys. And where were you in all of that . Im the youngest. Number nine. It was kind of like boot camp. As soon as you get to a certain age, heres how you do laundry. Heres how you clean. Narrator Dad Michael was an exmarine and a former city cop. Mom, mary ellen, worked at the Campus Bookstore in nearby greeley. Annies sister, older by 13 years, was tina. Was she something like an older aunt to you or something or as much as a sister . She was very much a sister to me. She cared for me. She played with me. She would play with us in our clubhouse. She would do Obstacle Courses with us in the backyard. Narrator wow. She was just always very attentive to us. Personality. Tell me what made her happy. What do you see her doing when shes smiling in your mind . Being with family made her very happy. She loved us kids a lot. Narrator tina was a little shy but a spirited competitor in high School Basketball and track. Finding suitable boyfriends was where she stumbled some, as Sister Susan recalls. Mom and dad did not approve of two of her young steadies. Yeah, she kind of found The Ones that needed help and she thought she could help them. Narrator but college gave her footing and studies in nursing gave her direction. Thats where she met a Guy Taking Classes to become a radiology technician. His name was John Sandoval. So what did your parents think of this john . I think my parents kind of liked him. He was a little older than tina. Narrator and just like that, tina was soon sharing an apartment in greeley, colorado with her new boyfriend, john. Kid Sister Annie, about nine at the time, thought it was all very exciting. He was quiet but sociable at the same time. He seemed really nice, well mannered, very polite to everybody. Complimentary of your sister . Annie oh, very much. Yeah. I really looked up to the relationship a lot. I thought they were a good fit. I thought it was a fairy tale. Narrator annie loved going over to tina and johns to play chinese checkers and mess about with their new dog cody. Tina had broken out of her strict mass on sunday catholic upbringing. What does your Childhood Mind Make of your sister and her boyfriend . I dont think any of my other siblings had lived with somebody before. So it was a whole new experience. And there was going to be a wedding. And there was going to be a wedding. And we were in the wedding. Narrator john and tina had found a chapel up in the rockies to exchange their vows. I was a Flower Girl along with my Sister Teresa and our sister kelly, whos our oldest. She was a bridesmaid. And it was just a nice little chapel, small ceremony with just family. It was really quick. Happy day . Happy day. Very, very beautiful. We took a huge Group Picture out in front of the chapel afterwards. Narrator john toasted his bride at the reception. Ive got the best woman a man could ever ask for. And our familys just getting bigger. And welcome to the family. Narrator tina opened presents. This is from annie. All right, its a book. Narrator and annie remembers tearing around the Reception Hall squealing with all her sisters. Its a time to be gleeful and happy and enjoy the time. Narrator Johns Cousin and best man, jessie, gave a little speech. I know theyre going to do well for Each Other. And thanks again for everybody making it. Narrator jessie, for some reason, set annies teeth on edge. Annie he was extremely quiet. He kind of made me nervous. I just had a feeling about him that i just couldnt put my finger on. You wondered what was going on or . Yeah. Yeah. He just didnt sit right with me. I kind of avoided him. Narrator and so after the toasts and happy tears, the new mr. And mrs. Were off to cancun for a mexican beach honeymoon. The snapshots show a happy couple. Annie was thrilled to get a souvenir. Cancun tshirts. And that was pretty cool, because wed never been out of the country or even flown on a plane. And heres tina going on a cool vacation. Narrator so a suntanned tina returned to her nursing studies. Happy forever after . Not exactly. Annie i didnt see it coming, didnt notice anything off kilter, and then suddenly we were moving tina out into a new apartment. Narrator Coming Up. Susan she wasnt very forthcoming in the beginning. I knew they were having problems and she had concerns, but she wasnt telling me. Me and my sister were really scared. Narrator had tina been keeping a secret . The mystery that would take 20 years to solve was just getting started. There was no body. There was no crime scene. There was no witnesses. Quite honestly, is it possible she is alive and shes living somewhere else . Narrator when dateline continues. When you have moderate to severe eczema, its okay to show off.

And he just treasured her and he made her feel really special. And she hadnt felt that way for a while. Shed been treated like dirt. Narrator came a long, long way, right . Yeah. He called her kitten and just was constantly just like, youre so beautiful. Youre so beautiful. I cant believe im with you. Narrator he might have been an eloquent sweet talker, but john seemed to have trouble holding a job. He never did finish his Radiology Class and found a string of part time hourly jobs working in a Liquor Store, a Customer Care Call center. About two years into the marriage, tinas Sister Susan could sense that something was off. She was feeling like maybe John Wasnt who she thought he was. Narrator did you scratch around on that . Susan A Little Bit. She wasnt very forthcoming in the beginning. I knew they were having problems and she had concerns, but she wasnt telling me a lot of what she already knew at that point. Narrator tina, it turned out, was keeping a secret about her marriage, a dark one. And she wasnt ready yet to disclose the humiliating truth, not even to her sister. Nursing school, meanwhile, was going very well. She dove into the field and found her passion, caring for other people. Tina soared. One of tinas fellow nursing students was Carol Shervin. She was as scared to meet her first patient as tina was confident. She literally pushed me in the door. You can do it. Shes giving you the pep talk. Carol shervin she said you can do it and she physically pushed me into the patients room. I think when it came to nursing, she was a natural. In command, confident . Confident. Not bossy in any way, but just she knew what she was doing. Narrator but carol knew almost nothing about Tinas Life away from nursing school. The shy teenager had become the nose in the Book Student and didnt socialize with her classmates. Sister susan had married by then too and she and her husband ended up getting an apartment just down the street from john and tina. So we could easily walk back and forth and see Each Other. And i had my daughter at that time and she was a toddler. And my sister loved children. Narrator susan would take her little girl to see Aunt Tina for coffees that became heart to hearts. Susan confided that she was unhappy in her marriage just as tina was restless in hers. And so she was actually really encouraging me to get out of my marriage. And so she really wanted to help me. And then she kind of made the leap before i did and started filing the Divorce Paperwork and moving out into her own place. Narrator by Summers End 1995, tina and john were done. When it cracked, what was the thing . I think it had been going on for quite some time before i knew about it. From what she told me later, she was confronting him about things that she was finding out about him. Hes not a good person. Narrator Kid Sister annie was clueless about why tina and john, her almost prince charming, were splitting up. But there she was helping to lug boxes from the old place to the new apartment. And john was there. He helped as well. And i asked him. I said, well, why is tina moving out . Whats going on . And he said, oh, dont worry about it. We just need A Little Bit of space. Dont worry. Well be back together soon. Did you think that was likely or . I thought it was, because i just, i admired the relationship. I idolized it. I believed him. You wanted that life for you. Yeah. Narrator but John Sandoval soon plummeted from Annies List of admired men because of something that happened just after theyd finished getting tina moved. He took Me And My Sister back to town. And he got us some Ice Cream cones and took us to the lake. And then he started driving down the Boat Dock into the lake. The Boat Launch . The ramp . Annie yes. In the vehicle . Yes. And Me And My Sister were really scared. We didnt know what he was. Doing it as a goof or . It was a different side of him id never seen. He seemed to be getting joy out of our terror. And the waters Coming Up over the hubcaps . Yeah. And we just didnt know what was going to happen. And then he stopped and backed up and took us home. And that was it. Did he become a category of a different person after that to you . Yeah. Yeah. Narrator john you idolized wasnt necessarily the same guy. Yeah. He scared us. Narrator scary and John Sandoval were just getting up to speed. Coming up. Carol shervin my jaw drops and im like, what . Narrator a separation and an obsession. Carol shervin she would look out over her balcony. She said his car would be there for hours. His car. Carol shervin his car. Theyre separated, but hes checking her out. Hes stalking her. Right.
