This week on Unknown Passage, we look at the disappearances of Angela Yanez in Zurich in 2007 and Tracy Splinter in Vals in 2016. \n\nTheme music: \u2063\nUndertow by Scott Buckley | https://soundcloud.com/scottbuckley\u2063\nMusic promoted by https://www.free-stock-music.com\u2063\nAttribution 4.0 International (CC BY 4.0)\u2063\nhttps://creativecommons.org/licenses/by/4.0/
