Russia’s top criminal investigation agency is probing the death of Roman Starovoit, a former transport minister whose body was found with a gunshot wound near his car, hours after President Vladimir Putin dismissed him from his post.

Russian lawmakers approved a new transport minister, one day after the body of his predecessor was found with a gunshot wound hours after being sacked by President Vladimir Putin.

Roman Starovoit was Russia’s transport minister until President Vladimir Putin fired him from the position on Monday. Just hours later, he was found dead in his car, with investigators saying that suicide is the most likely cause.
