"Hrabovskiy is on a missing list, and I don't rule out that he is no longer alive," she told the reporters during a break in a court hearing against Aleksandrov and Yerofeyev Tuesday.
According to Sokolovska, neither the police, nor the SBU Security Service of Ukraine knows the whereabouts of Hrabovskiy.
"The law enforcement agencies continue the search, but to no avail. He did not cross the borders of Ukraine, and there are no other data about him," the lawyer said.
The last time Sokolovska talked with Hrabovskiy on March 4, and he was going to attend the court session.

Sokolovska also said that the disappearance of Hrabovskiy, as well as attempts to remove her from the protection of the Russian GRU officers, had been associated with delaying the trial by the prosecution.
