The soldier's death was murder or suicide?

The postmortem of soldier Mnatsakan Mnatsakanyan, who died in Stepanavan military unit, is over in Forensic experts center.
The postmortem was attended by Helsinki Association member Ruben Martirosyan.
Martirosyan mentioned in the interview with lurer.com, that there is an important contradiction in the case: "According to Mnatsakan Mnatskanyan’s military unit vice-commander, Mnatsakan has been in depression in his last week, and that the command has taken him to psychologist for examination, and the latter told that everything is ok. They say that Mnatsakan conducted a happy life and service in his last days, and that his mother talked to him on the eve of his death, and the latter was in a good mood, happily talked to his parents.”
The expert told in the interview with lurer.com, that the examination of the body does not allow to clearly state whether it was a suicide or he was hanged, because any obvious traces connected with death have not been found on his body.
“At the moment we are unable to tell it’s suicide or murder. We cannot tell, because we still don’t have the results of some important examinations: first of all we need the examination of his clothes, in order to decide whether violence was applied against Mnatskanyan or not, are there rips, blood traces or not. It’s not excluded either,: said Martirosyan.
He mentioned, that they need to understand how Mnatsakanyan managed to hang himself on 2 meters height: “It’s to be revealed what facility was put. When the parents went to the room, where Mnatsakan was found hang, there wasn’t any item, chair or any other facility, that Mnatskan would be able to hang himself, and without it, most probably, he wouldn’t be able to hang himself.”
Martirosyan also mentioned, that at the moment, the issue needs to be left hanging in the air and later, if respective facts are acquired, to refer those.
For the expert, the death case is a riddle. But the death causes should be found only and only in the service, since Mnatsakan didn’t have family problems, was the family’s only son, physically healthy, strong and kind. “ His heart is 150 grams more, than the youth of his age.”
Note, that on October 1, died RA AF’s N military unit ordinary soldier, 18-year-old Mnatskan Mnatskanyan in peaceful conditions.
As MoD repotted, the soldier died when maintaining the security of RA boarder and the Armenian nation.
Later Artak Nazaryan’s sister Tsovinar Nazaryan, wrote on her Facebook page, that it’s been revealed that Mnatsakan Mnatsakanyan was an important witness in Artak Nazaryan case.
“Mnatsakan is my brother’s military base cook Arman Arshak Mnatsakanyan’s cousin. This was the witness, whose service was prolonged, for him to stay under the authority of Military Police when being questioned in the court, he was vanished after being discharged from the army, the case was moved to Idjevan, the accusatory side was strengthened by involving another Prosecutor, then for 7 months they were unable to detain him. According to the notifications given by Vagharshaat police he was either sick, or was under medical treatment abroad. NSS responded to our inquiry, that he has never left RA and he finally came, spoke a couple of words and left…”
Expert Martirosyan, referring to the question, whether he sees a possible connection between the cases of Nazaryan and Mnatsakanyan, said, that not having any facts, it’s not correct to seek such a link.
“If we find a connection, I’ll report, but now I can’t see such a link. I don’t have grounds and suspicions for expressing such a viewpoint. Though, the fact that Mnatsakan could be murdered, is not excluded,” concluded Martirosyan.
