Ledjon Brakaj, the 36-year-old Albanian who was arrested in Malta for a double murder in Greece in 2015, is suspected of having other accomplices.
A retired Greek officer, Thanasis Katerinopoulos, told the Star that "there is no such thing as a perfect crime".
"Investigators searched the house, collected all the evidence found at the crime scene, including the perpetrator's DNA. From the DNA it was identified and then checked. An arrest warrant has been issued and the person is in Malta, where he has been arrested by the authorities. As I said, there is no such thing as a perfect crime, as long as the investigators do their job properly," he said.
The former senior Greek police official says that the crime was well organized, but a mistake was made, which proved fatal for the Albanian.
"In the past, there were equally cruel crimes, only here the difference is that after killing the two people, he set fire to the house. But you saw that despite the fire, the hat did not burn, the officers who did the check took it and this is where the identity of this man was found, now he will be taken to the prosecutor's office and maybe there he will find out if he had other accomplices or if he committed it alone. It's unlikely that he was alone, that's my assessment," revealed Katerinopoulos.
"I think there were accomplices. Not a chance, that's my assessment. There must have been two in the house, the nephew would have reacted but managed to overpower him. Logic says there was another," he concluded.
