XI. Nel learned that Elgar, the owner of the biggest house in the place, would be out of town for three days with no one left to watch the house. He called his friends Ben, Ardo and Gorio and they planned to take the valuables in the house while Elgar was away. Nel and Ben would go inside the house, Ardo would serve as the lookout, while Gorio would stay in the getaway car. When Elgar left, they carried out their plan to the letter. Nel and Ben went inside the house through the backdoor which was left unlocked. None of the rooms and drawers inside were locked. They took the money, jewelry and other valuables therefrom and immediately left using the getaway car. After driving for about one kilometer, Nel realized he left his bag and wallet with IDs in the house and so he instructed Gorio to drive back to the house. Nel just went in thinking that the house was still empty. But to his surprise, Nel found Fermin seated on a bench with Nel's bag and wallet beside him and appeared to be texting using his smart phone. Nel took a golf club near him and hit Fermin with it. Fermin shouted for help, but Nel kept hitting him until he stopped making noise. The noise alerted the neighbor who called the police. Nel, Ben, Ardo and Gorio were caught. Fermin died. What is the criminal liability of Nel, Ben, Ardo and Gorio? Explain. (5%)
