I know Oman is a peaceful Muslim nation (seriously, it is), but there is likely something not good about this death.
He's had a long history of alcoholism. Some people's bodies just can't take it. Grateful Dead keyboardist Ron "Pigpen" McKernan died of alcohol-related health issues at 27. GnR bassist Duff McKagen barely survived alcohol-related pancreatitis at age 30.
You're right about Oman. Most friendly people I've ever met. Beautiful country.
