Did Stalin's son, Yakov, commit suicide?

Yakov Stalin is not Anna Karenina. There is another version. https://history.wikireading.ru/266203 http://kv-journal.su/content/o-syne-stalina-yakove June 24, 1941. Yakov took command of the 6th artillery battery of the 14th howitzer regiment of the 14th Tank Division. July 16, 1941. Yakov's orderly - A. Kovalev: Yakov got the task of moving the battery closer to the front line. The column was bombed by the Luftwaffe. The horses, Yakov and the adjutant fell from the explosion of the bomb. However, allegedly, "Yakov" quickly recovered. This is already a lie. Mikhail Grigorievich Grigoriev, Colonel-General, commander of the first combination of ICBMs (Plesetsk Cosmodrome), First Deputy Commander of the Strategic Missile Forces of the USSR. He said that he saw Yakov died on the battlefield. Perhaps he did not see personally, because he fought 30 kilometers from Yakov. Stalin's adopted son, General Artem Sergeyev, claimed that Yakov Dzhugashvili had never been a prisoner, but died in battle.

The Germans interrogated "Yakov" between July 11 and 13 (the real Yakov was still at war)! The Germans did not know in which regiment Yakov fought! This is absurd! The name, rank and regiment are allowed to speak to any prisoner of war.

Doctor of historical sciences Sergey Devyatov: "There are about 10 photographs of Yakov Dzhugashvili in captivity. Specialists of one of the Defense Ministry's centers analyzed them. This is a very competent photomontage. ... when the photos were over, they made a mistake by giving a "mirror image" of one of the photos - on it there is a clasp on the jacket on the other, "the female side"." "In German documents, it is said that Yakov Dzhugashvili - the son of Stalin owned three languages: German, French and English. " The real Yakov at the institute and the academy did not study German and English."

Total: There are no photos (10 photos-it's not many) of the prisoner Yakov. Traces of photomontage 10 photos of the prisoner Yakov. No audio record of the prisoner Yakov. There are no video records of the prisoner Yakov. The note of the prisoner Yakov does not match. Witnesses in the camp never knew Yakov before the war. The Germans burned the body of the prisoner Yakov.

I found this website which gives what seems to be a transcript of the Sunday Times article.

The article is based heavily on the statements of the British soldiers who were in conflict with the Russians over political issues. I don't know how credible their claim that "he refused to clean the shitter" is. They also suspected the Russians were given "preferred treatment" by the Germans.

The German Wikipedia article on him indicates a very difficult father-son relationship. The son became an engineer without his father's help and worked in an automobile factory before joining the army to become an artillery lieutenant.

The Gestapo reported that he'd had a prison psychosis and his death appeared to be a suicide.

It seems the best argument for the suicidal aspect of his death is presented by this report from The Telegraph:Revealed: how Stalin's brutal massacre at Katyn shamed his PoW son into suicide. Some of the same elements are involved such as the electric fence, and the disputes with British officers. But the main gist of this article is the suicide aspect of the 'attempted escape', and its speculation over the cause:

Now it has been disclosed that the Russian artillery lieutenant was so overcome by shame at the news of his father's massacre of 15,000 Poles at Katyn in 1940 that he committed suicide by flinging himself on to the camp's electric fence.

...The disclosure, given credence by Professor John Erickson, the world's leading authority on the Soviet-German War, has been published in the latest edition of the Soviet Military Journal.

About the conflict with the British:

A decade ago Professor Erickson and the Russian investigators had concluded that his death could have been suicide prompted by a violent confrontation between himself and a group of British prisoners of war. The new evidence, however, now firmly blames the Katyn massacre.

...and later,

"This evidence does go some way to exonerating the British officers whose taunts were believed to have pushed Yakov to breaking point," Erickson says, "but it also highlights the devastating effect the Katyn massacre had on Yakov. He could not live, I believe, with the accounts he was given of the massacre ordered by his father.

Concerning the shooting:

Though the official SS report at the time indicated that Dzhugashvili died after he was shot by a guard as he ran towards the wire, it is now known this was a fictional account compiled to impress Heinrich Himmler. "The guard certainly shot Yakov four times," Professor Erickson, who has viewed the evidence, confirms, "but it is now known that he fired the bullets into Yakov's already dead body."

So this historian believes the shame over the revelation of the massacre at Katyn, as well as conditions in the camp, finally accumulated to the point where Yakov couldn't take it any more.

"It is clear that Yakov, who had become close friends with the Poles and had made two abortive escape attempts with them, was so distraught when goaded with the news of his father's massacre of the Polish officers, which was revealed in German newspapers in 1943, that he took his life. Driven to despair by the horrific conditions in the camp - he was emaciated and on the point of starvation - and the strain of the propaganda campaign the Germans had involved him in, the news that his father had sanctioned the Poles' murder was the final straw."

and..

"Though the Poles were killed at Katyn in 1940, their bodies were not discovered by the Germans until March 1943. When a camp guard showed Yakov the newspaper reports of the discovery, taunting him with the words, 'Look what you bastards did to these men. What kind of people are you?' Yakov was devastated. He was at the end of his tether. A month later, on April 15 1943, unable to live with the shame, he took his life."
