I wonder how much weight has been put on the concussion. I have a hard time believing she disappeared because of the concussion. How severe was the hit on the head? What was the context?

Sydney Kaitlyn West, 19, went missing in San Francisco on September 30, 2020. She took a rideshare to Crissy Field near the Golden Gate Bridge, a location she frequented for exercise and photography, and was captured on surveillance footage around 6:45 a.m. walking toward the bridge. Foggy conditions obscured much of the camera coverage.

Her backpack was recovered near the bridge, but her phone and headphones were never found. She had been on a gap year after a concussion earlier in 2020 and planned to return to the University of California, Berkeley in fall 2021. There has been no activity on her phone, bank accounts, or social media since she vanished. Her family, who say she would not have intentionally disappeared, has offered a reward for information.

Does anyone have information about Sydney’s movements around Crissy Field that morning or recalls seeing her or her backpack near the bridge?
