her questions about the family, but she gave no answer. In conversation, Josef Thaler claimed to know which family member was sleeping in which room and stated that they had a lot of money. During their conversation, Rieger noted that there was another person nearby. According to her statement, Josef Thaler and the stranger had looked at the machine house and turned their eyes upwards. Paul Mueller Author Bill James, in his book, The Man from the Train, alleges that a man known as Paul Mueller may have been responsible for the murders. Mueller was the only suspect in the 1897 murder of a Massachusetts family, and James believes Mueller killed dozens of victims based on research in American newspaper archives. The Hinterkaifek murders bear some similarities to Mueller's suspected crimes in the United States, including the slaughter of an entire family in their isolated home, use of the blunt edge of a farm tool as a weapon (a pick axe), moving and stacking bodies of the victims, and the apparent absence of robbery as a motive. James suspects that Mueller, described as a German immigrant in contemporary media, might have departed the US for his homeland by 1912 after private investigators and journalists began to notice and publicize patterns in family murders across state lines. Legacy Many books and newspaper articles have been devoted to the murders. A series of articles by Josef Ludwig Hecker in the Schrobenhausener Zeitung revived interest in the murders. A documentary film, Hinterkaifeck – Symbol des Unheimlichen (1981), is based on the Leuschner book; Hans Fegert adapted the book, directed the film (shot on Super 8, with sound), and was the cameraman. The film was shown regularly in Ingolstadt. Ten years later, Reinhard Keilich's play Hinterkaifeck – Deutschlands geheimnisvollster Mordfall (1991) was produced, and at the same time Kurt K. Hieber produced another documentary, shot on location, and shown on television and in local cinemas. Also in 1991, radio station Funkhaus Ingolstadt aired a documentary, Hinterkaifeck – auf den Spuren eines Mörders, and the Abendzeitung (München) ran a series of articles called Die sechs Toten vom Einödhof – Bayerns rätselhaftestes Verbrechen. In 2007, 15 students of the Polizeifachhochschule (police academy) in Fürstenfeldbruck examined the case using modern criminal investigation techniques. In their final report (in German), they confirmed the meticulousness of the investigation at the time, but criticized the lack of professional forensics. In
