Bosnian Slavisa Z. had recently served a six-year sentence for smuggling cocaine. He was in the process of preventing his eviction. On September 11, 2014, he was caught with fellow suspects on a boat with 31 kilos of cocaine off the Moroccan coast off the Spanish enclave of Ceuta. Through good behavior, among other things, he was released early.

According to Sur newspaper, it appeared that Z. had turned away from crime.

Last week, was the first shooting on the Costa del Sol after partial lifting the Spanish curfew. A British man was admitted to a hospital with gunshot wounds to his legs.
