Criminal field expert Ervin Karamuça has raised strong suspicions about the mysterious death of four Russian tourists in Qerret, as he said that this is a sophisticated murder that may be related to the high military position held by the father of the Russian family. 

The expert says that to investigate this event one must see the entire itinerary of the Russian family. He added that if it is like the latest assassination in England in 2018 of Putin's critic, Nikolai Glushkov, then the materials used are very sophisticated and the murder is difficult to detect. 

"The head of the family was a senior military man. Neither gas, nor high temperature, nor asphyxia, nor drugs do this. These can not do the same in the fourth. This raises a great deal of doubt. May have been used… There may be a more sophisticated background than that. You have to investigate the kitchen, the neighbors and the whole itinerary. Poisoning may have occurred elsewhere. In the hotel you have to have a daily routine. Members may have been recruited at the hotel to perform this service. The foods that have been consumed in Macedonia should also be seen. If it is the same as in 2018 in Britain, then substances that our laboratory never identifies will have been used. The victim does not feel them. It affects the skin and is indistinguishable. Secret murder. It is a great challenge to be discovered," said Karamnuça. 

Further, Ervin Karamuça revealed a conversation with a Russian colleague whom he had jokingly asked if they were preparing level four of the deadly elements for the opponents and he had told him that they have level four and are already working on level 5 . 

Karamuça called this murder very serious, saying that a battle between secret spies occurs for the first time in Albania, with the latter choosing to execute the target abroad. 

"I said to a Russian colleague, 'Didn't you start with the 4th generation?' He replied ‘we started with the fifth because the fourth is ready’. I mean they are advanced. If so then it is very serious event, as it becomes a battle of foreign secret spies. This has not happened before. They bring the objectives abroad", said Ervin Karamuça further.
