'As the investigation into Steven’s death is ongoing, we are unable to provide information beyond what the Fullerton Police share publicly,' the letter read. 'What I can do, however, is join all of you in adding to the tremendous outreach of love and support that has already embraced our Titan Family during this tragic and difficult time. That begins with pausing in thought and prayer for Steven, his family, and all Titans who are grieving and grappling with the reality of such an unspeakable act and tragic loss in our community.' >> Read the full letter here Read more here.
