i think that's one of the reasons tad cummings was able to move in on her so quick. >> reporter: jason whatley is the thomas family's attorney. do you think he targeted her? >> no doubt. >> reporter: he sought her out? >> no doubt. he was specifically grooming this child for a very specific purpose, and that was a relationship. he chose a girl that was clearly having issues, because she went to him for, quote, unquote, "counseling." she was the perfect victim. >> reporter: as part of the seduction cummins portrayed himself an international man of mystery. >> apparently he told a lot of tales about his fictional background. he's a cia operative. he's an fbi agent. he's a millionaire. >> reporter: anthony thomas says his daughter was impressed with cummins' alleged exploits. >> and i said, "you're telling me he's been in these fbi and the cia."

you. i love you." and she told her friend erin she had big news about a relationship. >> she said she really liked this guy, she really loved him, she really wanted to be around this guy all the time, 24/7. >> reporter: that carelessness made the situation highly combustible. and on january 23rd, it all blew up when a middle school student reported seeing cummins and elizabeth kissing in his classroom. >> this was an honors student who saw them kissing. >> reporter: that 12-year-old honors student later described the kiss to detectives as "a romantic peck rather than father-daughter type." the school, and eventually local cops investigate. elizabeth denies everything. >> i said, "why is the sheriff's deputy calling me about an incident at school?" she said, "oh, yeah. oh, yeah, some girl lied. it's nothing. nothing happened." >> she told me that she had gotten in trouble at school because her teacher was calming her from a panic attack. and some girl walked

it and told everybody that they were kissing. >> reporter: cummins continues the cover-up. on february 1st, in an interview with detectives, he describes the relationship as "that of a father figure at school." and denied ever kissing elizabeth. a few days later cummins is suspended. how did he explain it to you? >> that, he was, it was either a, someone telling a lie, or thought they saw something that they didn't, and that it absolutely did not happen. i had no reason not to believe him. 31 years of marriage, you know, with no problems, why would you not believe him? >> reporter: for many it was hard to believe. and the already bullied teen now marked with a scarlet letter of sorts. >> there were things being said that were extremely hurtful. >> reporter: elizabeth's father told whatley elizabeth faced ridicule and had been called

and now, "20/20" continues. >> reporter: it's monday morning in columbia, tennessee. the beginning of the work week for most. the beginning of a new life for tad cummins. "a beautiful day to start," he posts on instagram. the 50-year-old tells his wife he has a job interview and needs to borrow her nissan rogue, but the disgraced teacher is about to go rogue in more ways than one. he took your car.

>> he did. he switched vehicles with me on the day that he left, because he was going out of town, not far, but far enough that where he didn't want to take the jeep so he took the rogue and he never came back. >> reporter: across town, that same morning, sister sarah says elizabeth was agitated. she kept on saying, "you need to wake up," and i'm like, "what?" and she was like, "if i'm not back by six, call the cops." >> reporter: elizabeth is not yet of the age of consent. her state of mind and her true feelings about cummins are still a matter of dispute, but in video obtained exclusively by "20/20," we see a friend pull up to the thomas house in the morning hours. a few minutes later, elizabeth emerges carrying what looks like an overnight bag and a backpack. it will be more than a month before her family sees her again. at 7:45 that friend drops elizabeth off at a shoney's restaurant.

8:32 a.m., cummins' silver nissan suv fills up at a shell station neighboring that shoney's. six minutes later, it pulls out. soon elizabeth is in the car with cummins and to date there is no evidence he physically coerced her. but would elizabeth willingly leave behind her family and that security blanket she holds so dear? >> she loved it. >> reporter: medication and makeup still sitting on her dresser at home. >> it's an abduction either way you look at it. you can either abduct by grabbing someone out of their house at night by force or you can abduct over time. >> reporter: that evening tad's wife comes home from work to find an empty house and a note from her husband telling her he needed to "clear his head," claiming he's headed to either virginia beach or d.c. he promises to return and makes an unusual request. asking her not to contact police. >> i was just in total shock when i read it. i just didn't know what to think. >> reporter: did you realize all of a sudden that he had been lying about everything, or -

>> at that moment, then i, i knew that it was all a lie. >> reporter: when elizabeth fails to return by 6:00, sarah senses something is wrong. >> i started feeling really guilty. i felt like it was my responsibility to take care of my sister, and i didn't take care of my sister. >> reporter: after hours of driving around searching, anthony thomas calls the sheriff and immediately points the finger at cummins. >> i said, "you guys need to hunt down tad cummins and see if he's in town. see where he is." >> reporter: easier said than done. when cummins breaks his promise to return home, jill breaks her silence. she tells cops he took two handguns and $4,500 from a loan he took out a week earlier. jill also say her husband refilled a prescription for cialis before leaving town. shortly after that, an arrest warrant is issued and tad

man. but tad cummins got what he wanted. he's got the girl and some separation. he's been gone for nearly a day before cops figure out what's going on. >> an amber alert issued for elizabeth thomas. >> reporter: the only possible lead, a cell phone ping from elizabeth's phone around 3:30 monday in decatur, alabama. and a disturbing update. her instagram profile changed adding wife. >> i was a little bit sick when i saw that. >> reporter: amber alerts go out in tennessee and alabama. on day five, wife jill holds a press conference to try to reason with her husband. >> your family wants their poppy back. please do the right thing and turn yourself in to the police and bring beth home. >> reporter: cummins might not have watched his wife's televised plea, but millions can't stop watching.

the small town teacher's case goes national. >> reporter: the tennessee bureau of investigation works to retrace cummins' steps in the days before he vanished, releasing this security video from a local tennessee walmart. cummins casually strolls the aisles, making repeated visits to one. the hair color aisle. >> we have a little bit of knowledge about where they were at the beginning of their journey and then it's really been kind of a cold trail. >> reporter: meanwhile, investigators keep working, looking through tad cummins' computer, discovering an unsettling search history that included googling how to marry a teen bride and looking up the age of consent. >> we've been able to develop a consistent pattern of behavior on cummins' behalf that indicates he planned this for some time before disappearing with elizabeth. >> they're putting up the green ribbons all over town. we've had prayer vigils where people have come

shows his support with a different kind of green. >> we're hoping that $10,000 will get someone to talk or tell us where elizabeth is. someone knows where she is. >> reporter: just as many are losing hope, a break in the case. a tip leads investigators to an oklahoma city walmart to recover this security footage. recorded two weeks earlier, it provides the first images of the two since they disappeared. tad cummins' hair and goatee now appear dark brown and elizabeth's hair darkened red. they buy some food and pay with cash. >> he's very smart. i knew he would try to change his appearance. >> reporter: in nebraska, another possible sighting. the local police post these security images from a mcdonald's onto their facebook page, but quickly discover it was one of many false leads. a month of no direction, no contact.

somehow this high school teacher with no priors is proving as elusive as a master criminal. >> he's not a stupid person. he's a smart man. >> reporter: and he still has the support of his family. >> no matter where you are, daddy, no matter what you've done, we just want you to come home. we miss you so much. >> reporter: you still sort of defend him? >> i do. i find myself defending him. >> reporter: why? after what he did to you? not only did he betray your marriage, he thrust your whole family -- >> i know. unbelievable. >> reporter: while the lights continue to burn bright for elizabeth's safe return, tad cummins has other ideas and other places to hide. >> we honestly just don't know. they're a bit of a needle in a haystack right now, so to speak. >> they could be anywhere. >> reporter: stay with us. like walking. hings. hey, honey.

in your rearview mirror. this was tad cummins' sell to elizabeth thomas, who was clearly open to suggestion, just days before she'd posted on instagram, "i want to leave, go away, far away." we know that tad cummins and elizabeth thomas drove out of tennessee with their bags packed for warm weather. he had shorts and t-shirts, she had her bathing suit, left her makeup behind. they headed south, then west, often evading authorities by sticking to the back roads. as their pictures spread in media across the country, they make that stop in oklahoma city, the first we know of, where investigators say they checked in to this super 8 motel. staff here telling investigators cummins asked for directions to the local walmart. that slip-up gave authorities the lead they needed to pull the

store security video. >> fugitives, particularly if they haven't been fugitives before, are fairly unsophisticated and they make mistakes. >> reporter: we learned that cummins made that mistake here at the super 8, using his real name, even giving the motel his real i.d., before checking in to room 114. this is what a single bed room looks like at this super 8. newly renovated, new linens, with a microwave and a refrigerator. all a far cry from where they would end up once tad cummins' money runs out. hotel staff say the two spent most of their time in their room, keeping to themselves. so you think his biggest trouble is going to be keeping her in line, on his side, under control. >> yes, keeping her in a place where she doesn't either want to run from him, call somebody, text somebody. maybe he said, "look, you're in as muc

your life will be awful if you go back there. you have to stay with me." >> reporter: throughout their journey, authorities say, cummins tries to cover his tracks, avoiding credit cards in favor of cash, switching out stolen plates twice, disabling his car's gps system, and even throwing out their cell phones to keep from being tracked. now, remember, tad cummins had a history south of the border. 20 years earlier he'd traveled to the rainforests of panama on a church medical mission trip. now, in need of a hiding place off the grid, it could be an ideal destination. did you ever hear him talking about being off the grid? >> well, we used to watch tv shows together about that sort of thing. >> i'm going to show you what it takes to get out alive of some of the most dangerous places. >> and, you know, i never would in a million

dreamed that he would be doing that. >> reporter: since elizabeth had no passport, cummins would have to sneak elizabeth by sea. off? authorities say cummins wanted to go by boat from here in san diego down to mexico. from there they could continue on to panama. >> it would be more like a movie stunt. that's not for real life. >> reporter: bryan zulka is the owner and captain of el gato sport fishing. is it easy to take a boat from here into mexico? >> no, it's not. you have to have the right boat, you have to have the right weather, you have to have the right skills and navigation, otherwise you're not going to make it. >> reporter: and we've just learned from investigators that cummins didn't get a motorboat. just a humble man-powered kayak. that might be fine in this tranquil channel, but once he'd hit the mouth of the ocean -- >> as you can see we're coming out here, these are good waves. this is easy a 4-to-8-foot swell real close together. >> reporter: no shock, cummins never got this far.

we don't know the precise route, but cummins and his teenage passenger ended up in berkeley, california. and here they learn of a remote commune on the northern edge of the state. believe it or not, there are still places in this country where people live completely disconnected from society. this is one of them. the black bear ranch, the focus of the documentary "commune." >> my slogan at the time was free land for three people. >> reporter: since 1968 it's been a place to shed both your clothing, and the inhibitions of life, if you can overcome the obstacles of getting there. we start the trip with fog and rain. paved highways soon turn into narrow dirt roads. the final gasp of civilization, this gas station in tiny cecilville. i'm eva. >> i'm griffin. >> reporter: here we found griffin barry, who says he met tad cummins on day 26 of his

you felt bad for him? >> yeah. >> reporter: you helped him out? >> yeah, yeah. i put $15 in his tank, you know? he was looking for black bear. he said he heard about it. >> reporter: were they lost? >> it could be a hard place to find. >> reporter: he wasn't kidding. so, we are trying to get to black bear ranch, we've been driving for 2 1/2 hours. no cell phone signal, very spotty gps, we thought we were close, but now it's impassable so we are going to have to turn around and try to find a different way to get there. we finally find ourselves at black bear ranch, where we definitely get the story we came for. those are chickens up there. >> yeah, chickens and ducks. >> reporter: the reclusive residents made us shoot this video on an older model iphone, and they had to vote before letting us use it. our host, april showers, gives us a tour. the commune's fortunes have ebbed and flowed over the years. today, there are only a handful of members left. most

events. >> several weeks ago this couple arrived and they failed to identify their true selves and identities. >> reporter: cummins and elizabeth used the fake names ofjohn and joanna, and told everyone they were 44 and 24 years old. the residents here had no reason to suspect anything different. >> we're an off-the-grid homesteading community. we don't have any television, radio, cell phone, internet. there's no newspaper delivery or other contact with the outside world besides what comes in and out of the driveway. >> reporter: they took the pair in, giving them a bed here in the main house, and sharing their food. but while tad cummins has left so much behind him, one thing he hasn't shed is his hot temper. so they didn't fit in here very well? >> no, they didn't fit in here very well. he brought that into our sacred space, this terrible behavior an
