Richard was declared dead. He had a cardiac arrest and was dead before reaching the hospital. The preliminary examination revealed no signs of struggle, so the doctors did not suspect murder. They refused to say anything else until the autopsy was done.
The gang members were sure that it was a secret attack by the enemy that took his life. There were also some gang leaders at the party who were hostile toward Richard. Any one of them could plan the attack.
Since Richard was a wealthy businessman, his sudden death naturally created an uproar in the hotel, which was sealed soon after the news was spread.
None of the guests were allowed to leave. But the gang leaders had already escaped sneakily before the police arrived.
There was chaos among the gang members. They were pointing fingers at one another. Sean and Richard's bodyguards were questioned.
