Another police officer quoted in Greek media claimed the gang had been identified and were well known.
“The three robbers are professionals. They have what we call a criminal past,” said the cop.
“That is, they are marked, they have gone through prisons and as it turned out, they are people with a strong anti-social element and a complete lack of emotions.”
He said the sadistic gang “used their hands” to kill the young mum despite having weapons in what was a “prolonged physical contact” with their victim.
The officer said the killers had the opportunity to walk away but didn’t.
“This clearly shows their intention to kill. In a robbery, the question is money. It was not necessary to kill to achieve the goal.
“They took the money, but they will be charged with murder. A crime that will send them behind bars for many years.
