“I’m getting a taxi from the Wiesn home,” the young woman told her friends before leaving the beer festival around 11:30 pm, daily Süddeutsche Zeitung reported on Thursday.
Shortly thereafter she phoned a friend – the last sign of life police have found.
Sabine P. didn’t show up for work on Monday at the Ludwig Maximilian University, where she is an administrator, and her family reported her missing on the same day.
Investigators have determined that she did not make it home to her Ramersdorf district apartment on Friday night, and her bank card has not been used since.
Police described the young woman as 1.6-metres tall, of slight build, with a youthful bearing and a high-pitched voice.
She was probably carrying a nylon backpack and wearing a dark sweatshirt, hip-length faux-leather jacket and navy sneakers.
Police are reportedly “investigating in every direction” and have asked for witnesses to come forward.
