Christian Brückner, the prime suspect in the disappearance of Madeleine McCann, has been released from a German prison where he was serving a sentence for unrelated crimes. Brückner, who has a history of sexual offenses, will be monitored with an electronic ankle tag for five years as part of his probation. Although he remains a suspect in McCann's case, he has not been charged due to insufficient evidence. German prosecutors believe he may have been in the area when McCann vanished in 2007, but investigations have not yielded conclusive results. The case continues to be treated as a missing person inquiry by UK authorities, while German officials suspect murder. The investigation has received significant funding, totaling over £13.2 million since 2011.
