Police are investigating the deaths of two Russian oligarchs who were found dead alongside their wives and children one day apart in their luxury homes in Moscow and Spain.
Vladislav Avayev, the former vice president of Gazprombank, was found dead of a gunshot wound in his Moscow apartment on Monday, according to Russia's TASS news agency.
Investigators have reportedly said their main theory is that Avayev shot his wife and daughter, and then himself.
Avayev, 51, his wife Yelena, 47, and their 13-year-old daughter Maria were found with gunshot wounds in the Russian capital.
They were discovered by Avayev's 26-year-old daughter Anastasia after she was unable to contact them, police spokeswoman Yulia Ivanova told state-owned new agency TASS.
The door of the 14th floor apartment is said to have been locked from the inside, with officials suspecting a murder-suicide. They believe Avayev's wife and daughter were shot before he was.
Anastasia told officers she found a gun in her father's hand.
The following day another oligarch, Sergei Protosenya, was found hanged in Spain with his wife and daughter stabbed to death, according to Spanish media.
