(BOSTON) -- Investigators were unable to grill the surviving Boston Marathon bomb suspect today because he is so badly injured that he is unable to communicate.
Gov. Deval Patrick indicated the severity of suspect Dzhokhar Tsarnaev's wounds when he said to reporters today that authorities "hope he survives, because we have a million questions."
Tsarnaev, 19, is under heavy guard at Beth Israel Deaconess Medical Center where he is listed in serious but stable condition. Officials said the suspect is unable to communicate, as he reportedly has a wound to his throat. He also has gunshot to his legs.
He has not yet been charged as of Saturday afternoon.
He is in the same hospital where his brother Tamerlan, 26, was brought early Friday after a shootout with police. Tamerlan died of his wounds.
When Dzhokhar Tsarnaev was taken into custody from the bottom of a boat in the backyard of a Watertown home Friday night, the suspect was bleeding badly and too weak to resist any longer, officials said.
Police believe Tsarnaev he was initially wounded Thursday night in the gunbattle that killed his brother.
Police said they found blood in a car he abandoned and blood at a house. Police said he went undetected by the massive manhunt because he had managed to get just one block outside the search perimeter.
It is unclear whether Tsarnaev was hit again during a final volley before his arrest in the boat.
