Unfortunately I see only 2 possibilities. The most likely is that he was robbed and murdered, the second possibility is he decided to end his life and gave his money and belongings (tv) to someone who helped him.
My question is how strongly were his roommates and acquaintances interrogated by police? Did they go through multiple interviews? Lie detector tests? Anybody who lived or "flopped" there needs to be strongly and thoroughly investigated. Those are the people from whom the answer lies. Also, did the police check for fingerprints solely in the bedroom or on the bedroom door? Although it would normal to have multiple fingerprints in the living area of the house, it would be less likely to have his "friends" fingerprints inside his bedroom.
