Tonight new details on the disturbing steps police say he took to prepare for the trip and how authorities mobilized citizens across the nation to help track them down. Heres abcs Kayna Whitworth. We are beyond elated. Words really cant express the feelings that we have. Reporter a familys nightmare finally over. Their daughter, their sister, is on her way home. A wonderful family that has been through so much. Reporter their 15yearold daughter, Elizabeth Thomas, rescued this morning after being allegedly kid named nearly six weeks ago by her 50yearold teacher, tad cummins. We know shes been through a lot of trauma, more trauma than just about any child should ever have to even imagine. Reporter Police Acting on a tip they received late last night. Around 11 00 central last night, from an individual in california who indicated he may have encountered tad couple minutes and Elizabeth Thomas. Reporter authorities closing in on an extremely remote area in Northern California. The caller indicated they had taken up residence in a cabin in a remote area in cecilville, california, within the last week and a half. Reporter police found the silver nissan suv parked near one of these cab by thats. The same car cummings was seen fueling the day the two disappeared. Authorities kept this car under surveillance for several hours and as daylight broke this morning, they were able to take tad cummings into custody ask safely recover elizabeth without incident. All we know is that shes apparently healthy and unharmed. Reporter the horrific ordeal finally over for the Thomas Family just as desperation was turning into lost hope. I left that meeting thinking there was literally nothing that these folks could do that hadnt already been done. Reporter their only clue this Surveillance Video captured at a walmart in Oklahoma City just a few days after their disappearance. The video revealing small changes to their appearance. Elizabeths hair dark and red. Cummings gray facial hair now brown. The pair dying food and paying with cash. They would have lived in obscurity for years without being found there. I mean, think about it. Tad cummingss had outsmarted everyone and gotten thousands of miles away from home. All the way up in Northern California from columbia, tennessee. Reporter the first signs of trouble happening months earlier. School officials began investigating the Health Sciences teacher after another student claimed to see him kissing elizabeth in his classroom. Cummings denied any wrongdoing but was later suspended. I didnt see this coming at all. You send your kids to school, you know you trust theyre going to be all right there. He is a predator. And she does not have any will of her own as we understand it. She is under his spell. Shes being controlled by him. Reporter cummings daughters, ashley and erika, last saw their father the weekend before police say he kidnapped 15yearold thomas. He was at my house saturday night before they left. He came over to see our newborn. And just hung out on the couch and talked. Just a normal night together. Reporter the very next day, his former student, Elizabeth Thomas, was seen being dropped off early in the morning of march 13th at a restaurant in columbia, tennessee. But before she left, her sister says elizabeth woke her with a warning. She said, if im not back by 6 00, you need to come find me, call the cop sxwlrs a short time later, this security footage showing cummings filling up his suv at a nearby gas station. Police say just days earlier, he took out a 4,500 cash loan. Sources also telling abc news that cummings researched camping and suvs and even watched a tv show about living off the grid. One of the keys when youre on the run is staying out of sight. In my view, he just was lucky. They were able to stay on the run this long because he does strike me as fairly unsophisticated as far as being a fugitive. Reporter hours after that gas station Surveillance Footage from monday, Elizabeth Thomas is declared missing. Sometime later another clue, a cell phone ping from decatur, alabama, over 80 miles away. That evening, tads wife jill came home to find a note from her husband. According to a criminal complaint, it said he was going to clear his head, that he would return, and asked for his wife not to call police. It also said that she noticed two hand guns were missing. I found out she was also missing, and that was what i knew. That was the moment that i knew. That it was all off. Reporter jill had thought tad was mentoring 15yearold elizabeth. She had been spending time at their home prior to the disappearance. She would come to him with her problems. About her past. I think he was mentoring her. Reporter but police say that a few months before he allegedly kidnapped 15yearold thomas, tad was secretly searching age of consent and how to marry a teen online. I think she went by her own choice, but i dont think she was old enough to make that choice. I dont think he forcefully took her. She was manipulated by him. Reporter according to the criminal complaint, police learned that cummings had filled a prescription for cyalis, a drug for erectile dysfunction, three days prior to leaving. While they were on the run, he had also purchased womens razors, chocolate, and ky jelly. Elizabeth thomas is not only the victim in this case, she is truly the only real witness. Any jury is going to want to hear from Elizabeth Thomas. Reporter Authorities Say thomas will be flown back to tennessee tomorrow. Our main concern is how is she emotionally and mentally . If she needs help, whatever help we can offer, we will make sure thats provided for her. Elizabeth is likely in crisis. When a girl really trusts somebody like a teacher, it can be a wonderful relationship. But in this case, it crossed lines. Reporter developmental psychologist Robin Silverman says, its a long road ahead for young Elizabeth Thomas. Shes going to come back and be confused, shes going to be filled with a lot of emotions that she needs to work through. And this is not going to be an easy road. Reporter after a month on the fbis most wanted list, cummings is sitting in a Siskiyou County jail awaiting arraignment, facing both state and federal charges including aggravated kidnapping and taking a minor across state lines for sex. Shes 15 years old. Shes a young girl thats with a grown man thats 50 years old. He needs to be held accountable for kidnapping this girl. Reporter the Thomas Family thankful and relieved their daughter is safe and sound today, thanks to a tip from a good samaritan. Youve got to understand we mobilized a nation during this six weeks. We mobilized a nation. And when you do that, something good most likely is going to happen because you cant hide from that many millions of people that are looking for you.

It was a chaotic scene in paris today as a gunman opened fire on police at one of the citys most popular tourist attractions. The attack coming just days ahead of the heated french president ial election. Now many are wondering if reaction to todays violence could propel a farright candidate whos been called Frances Donald trump to victory. Abcs chief Foreign Correspondent terry moran takes us on a road trip through a changing europe. Reporter one of the most beautiful streets in the world. The iconic champselysees on lockdown tonight. A gunman armed with a militarystyle weapon opening fire. One Police Officer killed, two others wounded. This man says he saw it all. Within two hours came that claim, that boast of responsibility by isis. All this three days before france goes to the polls in the first round of a bitterly contested president ial election. A leading contender in the president ial race, Marine Le Pen, the candidate everybodys watching. A farright nationalist with an incendiary antiimmigration argument. This is our home, a rallying cry reminiscent of a familiar refrain. And america heirs reporter the u. S. President today sending his condolences. Eye seen a very, very terrible thing going on in the world today. Reporter for france, for all of europe, this is a moment truth. Last month we went on a road trip across these political battlegrounds where the candidates future will be decided. The big question, has the election of donald trump in america and the grim uncertainties of this age of terror emboldened the populist movement around the world, and could the Ripple Effect mean the end of europe as we know it . First stop, paris, the city of lights, now also known for the everpresent reality of terror. Were going to the headquarters of the national front. Were going to go and talk to some of the younger members. So this is where it all happens, right . Why, why sign up with madam le pen . Shes saying like trump did in the u. S. , make france great again. She has a strong, really strong message. And she brings hope, more jobs, less immigration. Reporter sounds familiar, right . But in europe, that human tide of refugees from the middle east has made the immigration issue even more intense. Le pen suggests immigration like this is dangerous, reminding voters of the constant threat of attacks like the massacre in paris almost two years ago now. Were in a special place. This bar is called labellee keep, the good team. The last time i was here, this was all shuttered. This is where one of the attacks on the horrible night of november 2015 happened. 20 person died here. 10 was in my life. Reporter gregory ridenberg was behind the bar when the terrorists opened fire. He cradled his former wife in his arms as she died. But even after experiencing the unimaginable, he is not a supporter of le pen who he sees as a fearmongerer. I cannot imagine the horror that happened here that night. And for many men, it would have made them angry. You can do nothing with angry, nothing. Reporter that sounds familiar too. Just like in america. Europeans are in a fierce debate about globalization. And like donald trump, Marine Le Pen is an economic nationalist. So we traveled two hours south to chateauroux to see if she can persuade people here to vote for her. Le pens campaign is both slick and emotional. Packaged populist anger. Marine le pen tells a story, a story about how these people here have been ignored by the establishment and that now, through her, they can take their country back. This feels like a lot of the donald trump rallies that i covered. Its more than just a political campaign. Its bigger than that. Reporter and we even saw the parallels to the Trump Campaign in the crowdi itself. This guy with the iconic Trump Campaign hat. Backstage, we were granted a few moments with le pen herself. Shes brusque, all business. Weve seen brexit in britain. President trump in america. And maybe le pen in france. How would you describe this political moment . Translator its a global movement. In reality its a rejection of savage globalization, of free trade thats been imposed for decades that benefited very few. If youre elected does that mean the end of the European Union . Translator eu is a political structure that i find deeply harmful. Think it should cede its place to the nations and to the corporations. Reporter but a big reason le pen is popular and feared is her railing against what she sees as islamic fundamentalism and against muslim women wearing head coverings or veils. She wants to band the socalled bu burkini on french beach. Translator in reality its a representation of radical islam. Women dont want to put on this kind of swimsuit. Its a uniform for radical islamists and radical islamists absolutely will not have a voice in my country. Reporter everywhere we traveled, from france to the netherlands where an election was held last month, we heard the same debate about nationalism and diversity. This is a city that made its wealth, and you can see it here, by being open to the world. Its a merchant city. The question in this election, has there been too much diversity . We need politicians who are not removed from the population. We want real people. Not the socialist rhetoric and [ bleep ]. Were sick of it. Reporter in the netherlands this guy, wilders often called the dutch donald trump, but voters didnt buy it. He finished a distant second. We had a moment with him while still in the throes of his campaign. You called for the banning of the koran, closing of mosques. What do you say to people who call that hate speech . Im not in the habit of banning books but this is a book that is more antisemitic and more dangerous its the holy book of a billion and more people in the world. Its a book full of hatred, of an ideology that does not want to assimilate. Reporter millions of voters across europe are rallying to that kind of message. Others hear only hatred in it. The next test, france and Marine Le Pen. With blood on the streets of paris tonight, her moment may be at hand. For nightline, im terry moran in paris. Up next, the exclusive new interview, Caitlyn Jenner speaking out. Why she may no longer be a trump republican. Hes hiding a card its time for you and your boys to get out of town. laughing left foot. Right foot. Left foot. Stop. Twitch your eyes so they think youre crazy.
