I find it very concerning as well. GG Bridge is walking/jogging distance, the bay is right there and a long swim is probably not the best idea (especially if toward the bridge). The stretch between Crissy Field and the bridge is rather desolate. It reminds me a bit of the young man who went missing in Australia.
Did she actually ever go to Cal? She took a gap year - but did she actually attend this year? Do we know?
All we know for sure is that she moved into a dorm in late August, classes started August 26 for the fall semester. It has been reported that she moved in with friends in S.F., but we don’t know when. She disappeared Sept 30. Whether she actually attended classes I haven’t seen reported for sure.
