Recent UP graduate here, used to frequent Christie hall daily. Been following you all since Owen's disappearance.
A few points here:
1. As someone who has been a student walking on Willamette MANY times -- night, day, dark, light, sober, drunk, you-name-it -- the recent direction change as indicated by the Trimet video has completely altered my idea of what might have happened to him. I used to walk to Fred Meyer's on the regular. It's the only grocery option around, and Willamette Blvd is the only way you would walk there really. Sunday night would be prime time to shop because every other waking moment there are study groups/dorm meetings/ athletic practices. Could have been on his way to purchase something, or meet someone at FM parking lot, and got held up... Recent news about the violent teens in NOPO has me wondering if they were involved. Fred Meyer footage should be investigated, if not already done.
2. The indication that his phone was turned off does not mean he was trying to avoid being tracked. In fact, if he had been meeting someone for controversial reasons, I believe even more that he would have had it charged/accessible for maps/contacting whomever he was meeting with/emergencies. This leads me to believe it was turned off by a third party or destroyed.
3. The hazing theories are utterly unbelievable to me. UP is, relative to other colleges, a VERY tame school. I participated on multiple club and D1 athletic teams there, none of which ever had issues with hazing. There is no Greek system so really the culture for that is non-existent. Compounded with the fact that this was literally hours before midterms, I'd really discount that theory.
4. It does not surprise me that UP has not released more statements, and in fact they may be encouraging students not to post publicly. I worked for the media there and had to deal with tight-lipped admin/corporate PR BS constantly. However, their efforts are likely much more in person than what we have access to online.
5. The access to mental health resources at UP was pathetic, and if he had some sort of mental health crisis (unlikely from descriptions of him, but possible), I am very sorry he did not have access to better services while there.
Hoping for the best for Owen, looks like someone who would've been in my friend group there.
