from the sfgate you linked:
“She, apparently accidentally, left her phone and identification in the restaurant; both were later picked up by friends.”

Odd to have left her phone and ID behind, when for the majority of young people, they are never without their phones. jmo.
Have they done an autopsy/toxicology? Of course, this may turnout to be something entirely different, but reading about this case brought to my memory a case of a college student in CO who jumped from a balcony and died. He had eaten a marijuana edible in cookie form. He was supposed to eat only 1/6 of the cookie, but he ate the whole thing, and had a psychotic reaction. (
