In the case of Ayleen, who was found dead in a lake in Hesse, the suspect admitted to having killed the 14-year-old. This happened in a multi-hour interrogation last Friday, said the police and public prosecutor on Tuesday in Giessen. In the presence of his defense attorneys, he admitted that he had caused the student's death on the night of July 22 "through physical violence and then sunk the body in Teufelsee near Echzell," it said.

The 29-year-old man, who had already been convicted as a teenager as a sex offender, also led the investigators to the crime scene in the area of ​​a dirt road in the Gießen district. He also showed the location of other items of clothing belonging to the killed student. The clothing is currently being examined in the Hessian State Criminal Police Office.

The confession was preceded by extensive investigations by the 30-strong special commission and the Gießen public prosecutor's office. Since the Hessian authorities took over the case in August, witnesses have been questioned, a large number of leads evaluated and forensic and digital forensic examinations carried out.

The body of the student from southern Baden was discovered in July in the lake in Hesse. The suspect and the girl knew each other from weeks of chats on social networks and a well-known online game. For tactical reasons, the police and the public prosecutor's office are currently not providing any further information on the history of the crime, the exact circumstances of death and the motive.

Ayleen disappeared on July 21 in Gottenheim in the Baden-Württemberg district of Breisgau-Hochschwarzwald and was found dead in a lake in the Hessian Wetteraukreis about 300 kilometers away a good week later. On the same day, special police forces arrested the previously convicted suspect in Friedrichsdorf near Frankfurt am Main.

The suspicion against the man is based primarily on the evaluation of mobile phone, cell phone and GPS data. This enabled the investigators to create a movement profile of the accused and get an idea of ​​the alleged course of the crime. In addition, personal belongings of the 14-year-old were found in his apartment.

The suspect initially denied the crime. As a teenager he had been in a psychiatric hospital for ten years for an attempted sex crime. By the beginning of the year, the man was in a program for recidivist sex offenders. In the spring he is said to have molested a girl again.
