Investigation in the Madeleine "Maddie" McCann case
Press release of 03.06.2020
In connection with the disappearance of the then 3-year-old British girl Madeleine Beth McCann on 3 May 2007 from an apartment complex in Praia da Luz in Portugal, the Braunschweig public prosecutor's office is investigating a 43-year-old German citizen on suspicion of murder.
The accused is a sex offender with several previous convictions who has been convicted of sexual abuse of children, among other things.
Currently the accused is serving a longer prison sentence in another matter.
The accused lived regularly in the Algarve between 1995 and 2007, including for several years in a house between Lagos and Praia da Luz. According to the information available here, during this time he was engaged in several odd jobs in the Lagos area, including catering.
Further evidence suggests that he also made his living by committing crimes, including burglary in hotel complexes and holiday apartments, and drug trafficking.
The public prosecutor's office in Braunschweig is involved in the investigation because the accused had his last residence in the local district before his stay abroad.
Within the framework of the investigations, which are being conducted by the Federal Criminal Police Office (BKA) on behalf of the Braunschweig Public Prosecutor's Office in close cooperation with the Metropolitan Police/Great Britain and the Polícia Judiciária/Portugal, the public is now also being publicly requested to cooperate. A corresponding call for witnesses with further information can be found on the website of the Federal Criminal Police Office:
