There are people who knows Dj Somebody better than any other people. Apparently the man was not as holy as people thought. He was involved in some business. There are some businesses that once you involves yourself into them you are signing a death warrant. He was a club owner and a taxi owner this are very much s business.
It could be that he was assassinated by his competitors. Business can be risky but it depend on the type of a business that you do. It might be that he wronged someone and then that person decided to eliminate him.
Mostly of people are running dodgy businesses and they associates themselves with dodgy people.
