I found this article that says Brittanee Drexel, who’s been missing for over a year now, will be honored at her high school graduation ceremony on June 23. She was a junior at Gates-Chili High School in Rochester, New York when she went missing, meaning she would have graduated this year. She was enrolled in a vocational cosmetology program and also played on the soccer team.
At the graduation ceremony, Brittanee’s mom will attend and accept an honorary diploma in her stead. I think that’s a really sweet gesture made by her school and her class. I suppose they could have set up some kind of monument for her at the school or planted a tree in her honor or something, but that would seem to imply that they think she’s dead, which is by no means certain.
