UPDATE: In a shocking turn of events, authorities confirm that Peter M, the ex-boyfriend of missing beauty influencer Stefanie Pieper, has confessed to her murder. The confession follows a frantic search for the 31-year-old, who vanished after a Christmas party on 22 November 2025.
Pieper was last heard from early the next morning after sending a text indicating unease about a shadowy figure in her stairwell. Neighbors reported a heated argument coming from her apartment in Graz, Austria, that night. When Pieper failed to appear for a scheduled photoshoot on 23 November, her friends alerted the police, prompting an immediate investigation.
Authorities quickly identified Peter M as a key suspect. The Austrian Federal Police revealed on 26 November that he had been seen leaving Pieper’s building carrying a suspicious roll of fabric. They noted he had made multiple trips to Slovenia in the days following her disappearance.
A breakthrough occurred when Slovenian police discovered a burning car—identified as belonging to Peter M—near a casino at the Austria-Slovenia border. He was apprehended shortly after. During questioning, he shockingly confessed to murdering Pieper following an argument, claiming he strangled her and disposed of her body in a suitcase that he buried in a forest near Majsperk.
Authorities confirmed the recovery of Pieper’s remains, though many questions remain unanswered. The motive behind the murder is still unclear, and police are investigating the involvement of Peter M’s brother and stepfather, who were arrested for allegedly assisting him in concealing the crime.
This tragic case highlights the urgency of addressing domestic violence and the potential dangers posed by intimate partners. As investigators work to piece together the sequence of events leading to Pieper’s death, the community mourns the loss of a vibrant influencer whose life was tragically cut short.
Authorities continue to urge anyone with information to come forward as they seek to clarify the full circumstances surrounding this heartbreaking incident. The investigation remains ongoing as the search for answers continues.
