My prayers are with the family and the brothers. What an awful discovery!!
It is interesting that all of his belongings were removed from his room. The story did not say where/if they found them. There is a possiblility of it being a suicide. Many suicidal people will pack up their things and "tie up loose ends" before their death. However, there's not enough info to tell for sure.
If someone finds a followup story, please post it.
