Austrian police say an autopsy has not revealed the cause of death of a 25-year old woman from Colorado whose body was found in her Vienna apartment.
A State Department official identified her as Lauren Mann from the town of Paonia in Western Colorado.
Police spokesman Thomas Keiblinger said Wednesday that Mann's body was found after she did not show up at the home where she worked as an au pair and her worried employer called police. Her employer said she was "very reliable" and it raised alarms when she missed work.
Police and firefighters who forced open her door Tuesday evening found her half-naked body on a mattress on the floor in apartment that was sparsely furnished, Keiblinger said. Mann was discovered near a "considerable amount of blood," according to reports.
A forensics team initially had trouble examining the scene because all the light bulbs in her apartment had burnt out and had to be replaced with the help of a ladder, Keiblinger said.
Keiblinger said Thursday that investigators are now awaiting the results of toxicological tests over the next few days.
Mann had been studying and working in Vienna for about three years. She graduated in 2012 from the University of Colorado-Boulder's College of Music.
