Answer:
Multiple possiblity based on picture I received with question.
Explanation:
1 It's evidently winter from the picture. Aleena cannot play golf. Plus she's holding hands of tom. Smells fishy. shes a liar.
2 Tom's shoe got blood. If he came to house after Bryan's call. He'll definitely not step on it. He's a liar.
3 Rafi was making coffee- is a bit difficult to digest. He carries Starbucks like one. Least possible that Rafi was making a coffee. He's also liar.
4. Bryan was sleeping wearing shoes. It's not believable. He's lying
5. Alex is wearing socks only. He wasn't going outside. He need to wear winter clothes like aleena to go outside. Alex shirt got stains of blood. It can be ignored as he is the first person to see.
6. It's a living room. Aleena and rafi cannot go to kitchen or outside without passing through living room. It's not believable that they didn't see him dead.
7. Deadbody is smiling. There's least possiblity of a fight.
8. It could be a planned killing by poison and then they altogether stabbed with knife to make sure he's dead.
