Another member of the Russian military was found dead under unknown circumstances this week.

Lieutenant General Vladimir Sviridov, 68, and his wife Tatyana, 72, were found dead on Wednesday in their bedroom, said the Kyiv Post. They looked to have been dead for about a week before their discovery, according to the newspaper.

Sviridov commanded the 6th Army of the Air Force and Air Defence of Russia from 2005 to 2009, per the Kyiv Post.The paper also reported that a Russian Telegram channel, Baza, said the couple did not appear to have died violently, and toxic substances were not detected in any preliminary blood work.

“What caused the death of Vladimir and Tatyana Sviridov is still unknown,” it said, according to the Baza channel.

During Sviridov’s time as a commander in the 2000s, he complained about the Russian army, saying Russian pilots were not trained well enough.

“A pilot must have about 100 hours of flight time per year for full combat readiness. However, this is not yet the case,” he said in an interview, as per the Kyiv Post. “The average flight time in the army is currently 25-30 hours.”

In another interview, he said that the army appointed poorly trained officers because they lacked skilled ones, the Kyiv Post said.

Critics and adversaries of Russian President Vladimir Putin have died in suspicious circumstances for years, but nearly two years into the war between Russia and Ukraine, the deaths seem to be ramping up.Last year Ivan Pechorin, a Russian energy executive, fell out of his boat into the sea and died.In August Yevgeny Prigozhin, the leader of the Wagner Group and orchestrator of a coup-like march on Moscow, died in a bizarre plane accident.

The Kremlin and Russian state media have not yet commented on Sviridov’s death, said the Kyiv Post.

Russian Major General Vladimir Popov said the death was “absurd”.

“When I found out about his death, it hurt my heart,” he said to News.ru. “It’s a shame that people of such a rank, who are worthy of attention and respect, go out in this way.”
