So the investigation has not found a physical accomplice but there is a possible moral accomplice.
Surely investigators could ask B to prove how he could afford to buy a block of land in the expensive area of Attica by asking for his bank accounts. If he says he paid in cash, where did he get the money from? Was it as a result of money laundering from drug money?
As Greek crime groups have infiltrated the shipping industry, which is used to traffic
cocaine and
heroin into the Greek mainland and abroad, could B and his accomplice have been involved in drug trafficking perhaps even by helicopter?
Did B secretly store it in his house? Is that why he had CCTV cameras to make sure he would know if C found his stash? Perhaps the day before C's murder, B found out that C had found his stash of drugs. He phoned his moral accomplice and they decided that there was now a threat that C (if she left B) would report it to police so they decided that C's life had to end so they concocted the burglar story and that B's accomplice would drive around and pick up the stash of drugs in the black BMW. They had already realised that they needed another base to store the drugs last April so they had gone to Souda in Crete looking for a house in which to build a base for drug trafficking.
Investigators need to find out the source of the information about B and his accomplice going to Souda looking for a place to rent. What proof does AK have of this?
That is my take on this. What's yours?
