Police authorities in Bulgaria`s village of Ludogortsi arrested Wednesday a 71-year-old man, who killed his step-grandson and threw his dead body in the toilet of his house.

The murderer, Emin Eminov, made full confessions, mentioning an absurd motive for committing the crime, which the prosecutors refused to announce.

The body of Erdoan Erdolan, 8, has been discovered in the toilet on Tuesday, five days after he was officially declared missing.

During a search on the scene, police officers found another human skull and some bones in the same toilet. They are supposed to belong to the missing son of the elderly killer, who is claimed to work in Germany for two years.

The Regional Prosecutor of the nearby town of Razgrad, Ognyan Damyanov, however said there is no data, proving the man has left the country.

The investigation on the case continues.
