The body of a 19-year-old boy was found in a central park in Bulgaria's village of Tsar Samuil on Sunday.
The victim, Byulen Hasan, died as a result of numerous head injuries, medical experts reported.
According to the Mayor Mehmed Yumer, the youngster has just come back from the capital city of Sofia, where he worked as a building worker.
In the fatal night, Hasan was on his way back to home after a night of clubbing.
The case is still under investigation as the police authorities said they work on two main versions - a killing after a drunkard's row or an accident resulting from huge alcohol consumption.
