A popular beauty influencer in Austria has been found dead nearly a week after she disappeared - and it's all because her ex-boyfriend allegedly confessed. According to the Styrian State Police, 31-year-old Stefanie Pieper went missing on Sunday, November 23, after returning home from a Christmas party. She was reported to have exited a taxi with a friend upon arriving at her apartment in the morning, but she never showed up to a scheduled photo shoot. When Stefanie "could not be reached," her family members alerted the authorities.
