It is always hard when it comes to missing persons. There are so many aspects that should be taken into mind when trying to solve a case like this, not to mention the situation of the friends and the relatives of the person that is missing.
The police see many aspects while they suspect even more. What if he's with that friend, or a completely different friend, what if he's kidnapped and captured, or maybe he's no longer alive, what if we never find him or find out what happened to him? The head hurts from the many open options, for which there is no answer.
