Russian scientist working on Covid-19 vaccine falls to his death from 14th floor window ‘in his underwear after being stabbed’ in latest mysterious violent death linked to coronavirus.

Biologist Alexander ‘Sasha’ Kagansky, 45, was found dead in St Petersburg
His death comes as six Russians plunged to their deaths from hospital windows earlier this year in Covid-related deaths.

Five of the victims were being treated for coronavirus whilst one victim was a doctor who had complained about PPE shortages.

The Russian Investigative Committee has opened a murder probe into the death of Dr Kaganksy and a 45-year-old male suspect has been detained.The suspect, who is reportedly a friend of Dr Kaganksy, has claimed that the biologist was in a mentally unstable state before his death and injured himself with a knife.

He claimed that Dr Kaganksy jumped from the balcony when he tried to take the weapon from his hands.

Law enforcement are investigating the circumstances of his death, say reports.

Family members of other victims have suggested coronavirus sufferers are experiencing suicidal thoughts from drugs used to treat them, causing them to try and kill themselves.

Dr Kaganksy’s death brings the number of coronavirus-linked window falls in Russia to eight, all but one of them fatal.
