Officials have released a name in the case of the American nanny found dead in her Vienna, Austria, apartment on Tuesday night, but beyond that, much remains unclear. ABC News reports Lauren Mann, 25, died by suffocation, though it notes that Vienna police rep Thomas Keiblinger earlier referenced a preliminary autopsy that found no indications of strangulation. NBC News echoes the report of suffocation, but CBS News and the AP report the autopsy was inconclusive, and their reports don't mention suffocation. CBS cites officials who on Thursday confirmed Mann was not strangled, shot, or stabbed.
The case is being treated as a homicide, and an official tells NBC News "third party involvement cannot be excluded"; police say there are no suspects at this time. Keiblinger says it'll take a week or two for the toxicology report to be completed, which has CBS saying her death "could be [a] mystery for weeks." ABC reports Mann failed to pick up one of her charges from school on Monday, but her half-dressed body wasn't found until 6pm the following day. The Colorado native was a graduate of the University of Colorado-Boulder's College of Music.
