The family of a missing 20-year-old Monument man says they are holding out hope that he's still alive after officials found his belongings near Lake Michigan.

Northwestern University, where Trevor Boehm was attending college, released a statement Thursday regarding his disappearance last Wednesday in Illinois.

In the statement they said that Trevor's jacket, which contains Trevor’s Northwestern identification card, keys, cell phone and other personal property, was found among the rocks on the shore of Lake Michigan on Northwestern’s Evanston campus.

Trevor's sister held a press conference Thursday night to speak on behalf of their family, tearfully saying they are hopeful Trevor will be found alive.

The following is the statement released by Northwestern University officials:

At approximately 11:30 a.m. today (Nov. 13), a Northwestern University Police Department officer found a jacket belonging to Trevor J. Boehm, a Northwestern University student who has been missing since late last week. The jacket, which contains Trevor’s Northwestern identification card, keys, cell phone and other personal property, was found among the rocks on the shore of Lake Michigan on Northwestern’s Evanston campus.

The University continues to work with Trevor’s family, and our thoughts are with them at this time.
