Authorities arrested a suspect at a Swiss refugee center in connection with the death of an American nanny, officials told NBC News on Monday.
Lauren Mann, a 25-year-old originally from Colorado, was found half naked in apartment in the Austrian city of Vienna last month. She died from suffocation, an autopsy showed, and officials said a "considerable" amount of blood was found at the scene.
A spokesperson for the Swiss Federal Ministry of Justice told NBC News that a man from the Gambia was arrested Thursday at a refugee center in Kreuzlingen, a town around 20 miles from the Austrian border.
Neither Swiss nor the Austrian authorities would identify the suspect to NBC News.
