The Guardia Civil believe that they have solved the murder of German teenager Stefanie Rüggeberg, nearly four months after her body was found hidden in the undergrowth on an estate near Llucmajor. Sources said that the alleged rapist and murderer is a German aged 40, whose whereabouts are currently unknown. He apparently shared a flat with Stefanie and her brother, and investigators only learned of his existence recently. An international warrant for his arrest has been issued. The sources said that the man is wanted by five courts in Germany for various crimes. The Guardia Civil are not releasing any information about the latest developments in the case, but sources admitted that the family had not informed them of the presence of the man, an acquaintance of Stefanie's mother, at the flat. The 15-year-old and her brother lived in a ground floor flat in Calle Sant Bartolome in Arenal. Her mother Silvia, her companion and his son lived in the same building. The alleged suspect reportedly rented a room in the ground floor flat. The Guardia Civil now believe that when she returned home, the lodger tried to maintain relations with her and when she refused his advances he attacked and killed her in the flat. It is then believed that to get rid of the body, he hid it in his car and then at night drove to Son Veri where he hid it in the undergrowth. The body was not found until six weeks after her disappearance, and was in an advanced stage of decomposition. At the time, all Stefanie's friends were questioned, and a police team went to Germany to continue its investigations there.
