Unsolved Cases

This is a page dedicated to information on some of the world’s most famous unsolved mysteries. At the bottom of each unsolved case, I have noted down my theory and what I believe happened. I want to be able to share my theories, but more importantly raise awareness for so many cases that still unfortunately remain unsolved.

The Unsolved Disappearances Of Alessia Schepp & Livia Schepp (2011) - Shreya Sachdev

DISCLAIMER: No disrespect is intended towards anyone that I talk about on this blog post. This blog post is for educational purposes and is being posted on this website in order to raise awareness about this case and to truly hope that the grieving families and friends of these victims find closure and finally find out what happened to their loved one(s). I have gathered all this information on the internet, but unfortunately I do not know how accurate or inaccurate it is. If I have made a mistake somewhere, then I apologize. It is not my intention to spread false information. 


In the suburb of Saint Sulpice in Lausanne, Switzerland, Irina Schepp lived with her twin daughters who were named Alessia and Livia and were six years old. Irina Schepp loved her daughters very much and were said to be the light in her life. Despite her failed marriage to Mathias Schepp, the father of the girls, Irina and Mathias were able to make their divorce work and both had successful careers as well as both lived in the canton of Vaud. Irina said that life was much better without her husband as the girls were not under his authoritarian rules. Despite the fact that Mathias was strict, he was said to have nothing but love for his daughters.

Alessia, Livia, and Mathias were looking forward to spending the weekend of January 28th 2011 together. Mathias picked the girls up on Friday and told Irina that he would drop the girls off on Sunday. However, the next day, he texted Irina and told her that he would return them on Monday dropping them off at school. Irina replied and told him that she would prefer it if he dropped them off at her house before dropping them at school. Mathias never replied.

Alessia and Livia were seen to be playing by neighbors that day, but by 5:00pm Mathias was seen to be crossing the border into France. He was no longer in the country and supposedly neither were his daughters. On Monday, the girls do not return to Irina’s home and Irina contacts authorities. A massive three country search is set out to find the missing girls. Swiss authorities searched Mathias’ boat as well as 60 other neighboring homes, but the girls were unfortunately gone.

Meanwhile, Mathias was drawing money from various spots in Marseille, France. He also sent a postcard to Irina before boarding a ferry to the island of Corsica. Though no camera captures footage of Alessia and Livia boarding the ferry with Mathias, a witness said that they saw the girls playing in the play area aboard the vessel. This is an unconfirmed sighting, but it is the last trusted witness account.

On Tuesday February 1st, Mathias landed in Propriano around 6:30am. Mathias took another ferry from Bastia to Tulane where he arrived Wednesday morning at 7:00am. At 9:13am, Mathias was seen on camera alone leading authorities to conclude that he was no longer with his daughters. He was spotted in Naples, Italy, around noon on Thursday February 3rd. By that night, authorities had caught up with him. However, Mathias had thrown himself under a train and was now dead. This meant that nobody could tell Irina where her daughters were.

Authorities and Mathias’ family believe that a mental breakdown over his divorce with Irina was what had caused Mathias to kidnap and kill his daughters. However, evidence indicates that Mathias put forethought to his getaway. A French newspaper claimed the entire plan was laid out in a will that Mathias left behind in a will, later recovered by authorities. Police also found internet searches for ferry schedules, firearms, poison, and suicide on Mathias’ home computer. However, perhaps the most telling piece of evidence concerning Mathias’ mental state came from the letters he sent to Irina while on the run. One letter implied that he had killed Alessia and Livia as the letter said “My dear, I wanted to die with my daughters, but it didn’t go that way. I will be the last to die. You will not see them again. The children rest in peace. They have not suffered, and now rest in peace in a tranquil place.” The letter also indicated that Mathias hoped that these letters would not lead Irina to take her own life. This was not the only letter Irina received, as Mathias had sent her 8 letters. 7 of the 8 letters contained money (4400£) Later, police also discovered two other letters that Mathias had tried to send to Irina but failed. These two letters contained 1500£ each. The final letter sent also said that he was “reasonably trying to talk to Irina, but that she’d respond with her lawyers. He said he was going crazy feeling as if he was losing his daughters and that he would always love Irina.” It seems clear from this that there were some strange issues going on between the couple, even after the divorce.

The search for the girls continued, but unfortunately not much came from it. Police found no biological traces of Alessia or Livia in the ferry cabin that Mathias had stayed in on the ride to Corsica. However, detectives felt that the witness who saw Mathias with the girls on the ship was a trustworthy source. Several witnesses in Propriano claimed to have seen Mathias, Alessia, and Livia in two locations. First, at a bar in which Mathias was seen talking to a blonde woman. The second sighting was from a resident in Propriano who was sure that she saw Mathias eating chocolate pastries with his daughters sitting with a brunette women.


  1. Some people believe that Mathias may have taken Alessia and Livia, because he thought he was about to lose them. Reportedly, he thought that Irina was going to move to Brussels to be closer to her family and that he wouldn’t get to see his girls again. Thus, he decided to kill his daughters to get revenge on Irina or to “die with his daughters” as read in the letter. However, no bodies have been found despite the massive search.

  2. Mathias didn’t kill his daughters, but sent them away to live with a relative. In 2014, an unnamed source wrote a letter to an Italian TV show that ran stories on missing people. The source claimed they’d forged documents to allow Livia and Alessia to enter Canada where they are supposedly living in the Montreal-Quebec border. None of the girls had passports when they left with Mathias, thus they legally should not have been able to cross the border.

Which theory do I believe?

It’s strange to read about a case that’s so close to me, as I live in Switzerland and was 10 years old when these girls went missing. After a lot of analysis, I have come to the conclusion that Alessia and Livia Schepp are still alive. I believe that Mathias loved Irina a lot, but he believed it was unfair that Irina was living with his daughters and got to see them everyday, and he could only see them on the weekends. He felt so detached from his family, and believed that he should be a part of waking up and seeing Irina and his daughters every morning. Thus, Mathias decided to find a trustworthy couple to send his daughters to. In Propriano, Mathias was seen with the girls whilst talking to a blonde woman. It is possible that Mathias had been talking to this woman online and found that she was looking for a daughter to raise. Mathias decided to sell one of his daughters to this woman, with money being completely insignificant in this situation. Mathias was also seen talking to a brunette woman whilst eating pastries with the girls. Thus, it is possible that Mathias was trying to get the girls to know this woman so that they would feel comfortable enough being left alone with her. I don’t believe that Mathias killed his daughters, because killing his daughters would mean killing a piece of Irina, and Mathias was said to genuinely love Irina and this is proven in the letters he wrote to her. Even though he loved her, he couldn’t stand the thought of being so isolated from his dream: his wife and his daughters living together every single day. Thus, he decided to commit suicide, knowing that his daughters were away from Irina and that he would not be missing out on anything. If he had truly wanted to kill his daughters and then kill himself, then why did he go to so many locations? He could’ve just done it in Vaud, Switzerland. The reason as to why he went to so many different locations was to first of all meet the woman who was going to be raising his daughters, and then he had to make sure that the girls had settled in and that everything was okay. Thus, he went to Italy to commit suicide because he had to stay alive to make sure that everything was going okay with the girls without getting caught by authorities. I believe that Alessia and Livia Schepp are still alive.
