A pensioner has confessed to killing and then chopping up the body of a 60-year-old man who allegedly swindled him in a land purchase last month, police said yesterday. The 63-year-old man, a retired laborer, claimed that Theologos Diatsidis had sold him two plots at Oropos, north of Athens, for 350,000 euros after claiming that there was treasure buried there. But the pensioner discovered that the land did not belong to Diatsidis, who had himself buried some gold sovereigns in the ground himself to convince the 63-year-old to buy the plots. The two men argued and Diatsidis was shot in the head. The suspect, who was not named, claims that Diatsidis produced a gun and it went off during the struggle. Officers said that the retired laborer has confessed to using a meat cleaver to chop up the body before dumping the parts on an abandoned building site. Diatsidis was reported missing on November 30. His alleged killer visited the 60-year-old’s family to explain to them what happened before giving himself up to police, officers said.
