It all began on May 3, 2007, the McCann family's vacation at a seaside resort in southern Portugal turned into a nightmare. It began when Madeleine's mother and father were having dinner with a group of friends at a restaurant near their house. They went to the apartment to watch their children when they suddenly noticed that the bed where their daughter was sleeping was completely empty. The disappearance of this 3-year-old girl left the world in complete sadness. To date, nothing is known about the discovery of the culprit. In the past, his parents were included as suspects, and more recently, a German prisoner known as Christian Brueckner was also included as a suspect. On May 12, Madeleine's family expressed their anguish and despair over Madeleine's disappearance. Portuguese police said the girl could be kidnapped but still alive in Portugal territory. On May 26, police published a description of a man who was seen carrying a child the same night as Madeleine's kidnapping. In June, a police chief in Portugal provided important forensic clues that could have been destroyed because the scene of the disappearance was not adequately protected. In July, British police sent their sniffer dogs to help with the investigation. Inspections were made of the apartment and Madeleine's parents' rental car. In August, 100 days after Madeleine's disappearance, police suggest the girl may not have been found alive. On September 6, police interview Kate McCann, Madeleine's mother, as a witness. Days later, detectives declare Madeleine's parents arguidos, a Portuguese legal term similar to suspects. Madeleine's parents return to the United Kingdom. Portuguese police say there is no new evidence to justify re-interviewing them. In November, Gerry McCann decided to publish a video in which he believed his family was watched by a sexual predator days before Madeleine's disappearance. January 20, 2008, Madeleine's parents published sketches of a suspect, based on the description he looked like a creepy man near the resort. In April, Portuguese police traveled to the United Kingdom to participate in interviews conducted by Leicestershire Police with friends of Madeleine's parents who had dinner the night of the girl's disappearance. May 3: The McCann family asks for prayers for the girl. In July, the police released their final report. Weeks later, they close the investigation and lift the "suspicious" status of the McCanns. November 3, 2009: Images of what the girl may have looked like at that time are published. April 2010: Madeleine's father says it's incredibly frustrating how the police in Portugal and the United Kingdom have done nothing about his daughter's condition for so long. November: The couple signs a publishing agreement for a book about Madeleine's disappearance. In May 2011, the book about Madeleine's disappearance goes on sale. In April 2012, the detective leading the investigation in the United Kingdom, Andy Redwood, said on a program that his team is seeking to close the case. An image was also created of what Madeleine would have looked like at age 9. The day after, the police refused to reopen the investigation. In May 2013, UK detectives identified several persons of interest. In July, Scotland Yard announces new evidence and new witnesses in the case, and a formal investigation is opened. In October, police identified 41 potential suspects. An image is presented of the man seen carrying a blond child aged 3 or 4 in Praia da Luz at the time of Madeleine's disappearance. In January 2014, British detectives returned to Portugal, perhaps planning some arrests. In June, a search was carried out in Praia da Luz, but nothing came of it. In July, the police questioned four suspects, but nothing came of it. In September 2015, it was revealed that the investigation had cost around $14 million. In April 2017, the four suspects were excluded from the investigation, and it was reported that a significant line of inquiry was underway. In June 2019, the British government will fund the Metropolitan Police investigation until 2020. In June 2020, police revealed a 43-year-old German inmate, identified as Christian B., is a suspect in this case. German investigators classified it as a murder investigation, implying that Madeleine is dead. Madeleine's parents thanked her, saying, "All we've ever wanted is to find her, uncover the truth, and bring those responsible to justice. We will never give up hope of finding Madeleine alive, but whatever the outcome, you should know that we need to find peace." April 2022 the portuguese prosecutor's office announces an official suspect in the case, the suspect was not identified but the prosecutor's office reports that german police had acted in response to this request, this comes after german police revealed in 2020 that they were investigating a man (christian b) in connection with the madeleine case, who is currently serving a prison sentence for drug offenses in germany. he also received a 7-year sentence for raping a 72-year-old woman. The Portuguese prosecutor's office denies certain rumors about the connection of an announcement with a 15-year statute of limitations for a crime. Even so, nothing is known about this little girl today.
