 The ambassador's wife is in police custody, as well as the policeman.

Mr Magalhaes said blood was found on a couch inside the ambassador's home and he was likely stabbed to death, as no shots were reported in the area.

 

But he said it was not yet possible to determine the exact cause of death, because the policeman had burned the ambassador's body in an attempt to cover up the crime.
A burned corpse was found on Thursday evening inside the car Mr Amiridis and his wife had rented.
It was parked under a highway overpass in the area where the couple had been staying.
"This was a tragic, cowardly act, but we worked tirelessly to crack this case as soon as possible," Mr Magalhaes said.
Brazilian President Michel Temer, in a letter addressed to Greek Prime Minister Alexis Tsipras, said the ambassador's killing had caused him profound sadness and he extended his condolences to the ambassador's family, friends and the Greek people.
The Greek embassy in Brasilia declined to comment.
In Athens, Greek foreign ministry spokesman Stratos Efthymiou said the Government also had no comment.
Mr Amiridis served as Greece's consul general in Rio from 2001 to 2004. He was Greece's ambassador to Libya from 2012 until he took the top Brazil post at the beginning of 2016.
