Update video from parents: “Investigation update: Please share this new short video on your social channels and - especially for people who commute or exercise on or near San Francisco’s Golden Gate Bridge on Wednesday mornings - Syd was last seen at approx 6:45am on Wednesday, September 30 on the Golden Gate Bridge. If you or anybody you know saw anything that morning or have seen Sydney since that morning, please contact SF Police 415-575-4444 and our private investigator at 925-705-8328. Leads continue to come in and all are being investigated. Thank you for your help and support to #FindSydneyWest #sanfrancisco”
From parents’ video transcript: “Sydney was wearing long black tights. She was seen wearing black shorts, at times, too. . . . She had her backpack for a period of time as well, that’s how she got around the city.”
It hurts to analyze this video, but note the deliberate temporal modifiers (“at times,” “for a period of time“). Suggesting that she may have been seen without a backpack on the GGB, or may have changed into either black leggings or shorts by the time she was last seen on the Bridge.
