The other people of interest are believed to be male students who confronted CR when he and Spierer arrived at her building about 2:30 a.m. from a local bar.

Wonder if any of these individuals also showed up at CR's apartment building 2 days later to confront him (according to one of the attorneys, I believe).
There's a reason not to insert yourself into cases---could wind up on a POI list. Personally, I don't believe in this, even in the name of so-called justice (group of individuals going to possible POIs to verbally or otherwise confront them in the name of justice). That's what LE and other legitimate, organized groups are for. Ah, youth. MOO
I presume they had no way of knowing she would go missing and they were inserting themselves into a case.
