Mack, a long-time resident of Thailand, had been missing for a week, prompting the police to review security camera footage in hopes of locating him alive. Unfortunately, their search led them to a horrifying sight. Mack's mutilated corpse was discovered inside a chest freezer at a residence in the affluent settlement of Nong Prue.
According to reports from the media, a woman who had met Mack shortly before his disappearance has been arrested. German mass-circulation newspaper Bild cited a source claiming that the meeting was related to the lucrative sale of two properties—a villa and a boxing hall—worth approximately 700 million baht (equivalent to around €18.2 million or $20 million).
During the meeting, Mack's 24-year-old spouse received two text messages from him. However, she was unable to contact him again afterward. A Thai couple informed the police that a German woman had hired them to deliver the freezer to the house where it was eventually found, as reported by the English-language Bangkok Post.
Law enforcement authorities identified a German man, a close friend of the German woman, through surveillance footage. He was seen driving a pickup truck used to transport the freezer. The investigation reportedly involves multiple suspects, including both German and Thai nationals.
Investigators have discovered that a significant amount of money is missing from Mack's bank account, suggesting a potential motive of extortion. It is believed that he may have been subjected to torture prior to his death.
Hans-Peter Mack, formerly a prominent figure at Munich corporate communications firm Media AG, was last seen driving his Mercedes sedan in the coastal city of Pattaya, where he resided with his Thai wife. The family issued a missing person announcement, offering a reward of 3 million baht (approximately $86,000 or €78,000) for information leading to his safe return, but there were no viable leads.
On Sunday, Mack's vehicle was discovered in the parking lot of a condominium in Nong Prue. Authorities found traces of a cleaning solvent in the car, including on the seats, dashboard, and steering wheel, suggesting an attempt to destroy evidence.
The German Foreign Ministry has acknowledged the case and is maintaining contact with Mack's relatives and Thai authorities as the investigation unfolds.
