NAKHON RATCHASIMA — A German man identified as Mr. Matthias, 41, who was wanted for violent attacks on at least six dental clinics and assaults on at least two dentists, has been found dead at his residence in Non Sung district, Nakhon Ratchasima province.
Police from Non Sung Police Station and rescue workers from Hook 31 Nakhon Ratchasima received a report at 5:20 p.m. on March 21 about the discovery. Officers found Mr. Matthias lying deceased on a bed inside his single-story home near Wat Don Chomphu. Initial examination revealed a large wound approximately two inches long on his neck, appearing to be from a sharp object, with blood soaking the mattress.
The room showed signs of someone having searched through documents, with belongings scattered throughout. Two Rottweiler dogs belonging to the deceased were guarding the body aggressively, requiring livestock officials from Non Sung district to remove the animals before investigators could properly examine the scene.

According to witnesses, Mr. Matthias’s Thai wife, who works in Prachinburi province, became concerned when she could not contact her husband. Sensing something was wrong, she called one of her husband’s friends who lives in Cho Ho sub-district in Muang district of Nakhon Ratchasima to check on him.
When the friend arrived at the house and received no response to calls or knocking, he sought help from the village headman and local residents. Together, they discovered Mr. Matthias lying deceased on his bed and immediately notified his wife, who rushed back home.
Police from Non Sung station have established two possible causes of death: suicide or homicide, and are urgently gathering evidence. Later on March 22, officers from the Nakhon Ratchasima Forensic Division revealed that they presumed the deceased had used the knife to harm himself, resulting in his death.
Upon examining the wounds on the body of this German man, investigators found the deceased’s fingerprints on the knife and no signs of struggle or assault in the surrounding area. The deceased’s action may have been due to stress, coupled with the fact that he had a history of psychiatric treatment.

Mr. Matthias had been arrested on March 18 after his case made headlines in mainstream media. He was accused of physically assaulting and threatening female dentists at several dental clinics in Nakhon Ratchasima city since November 2024.
Police had not previously pressed charges, claiming the German man failed to appear when summoned, and other incidents went unreported as clinics believed Matthias suffered from mental health issues.
According to his wife, Mr. Matthias had previously received psychiatric treatment in Germany and lost his job due to mental health issues before relocating to Thailand. Since moving, he had refused treatment and medication, choosing instead to self-medicate with cannabis.
