BOSTON, Mass. -- Boston bombing suspect Dzhokar Tsarnaev continues to be guarded around the clock at a Boston hospital. He's listed in serious, but stable condition.
However, at this time he can't be questioned by investigators. Sources say because of the injuries to his throat, the 19-year-old suspected terrorist bomber cannot talk.
"All the law enforcement professionals are hoping for a host of reasons that the suspect survives because we have a million questions," said Massachusetts Governor Deval Patrick, "those questions need to be answered."
In a still photograph taken right after his arrest, the college student's neck area appears covered with blood. The younger brother's escape was busted when a man found him hiding in his backyard boat.
A series of thermal images taken by a state police helicopter shows a white image of an object projecting heat.
In another still photo, you can make out the suspects feet in black lying in the boat. Later, a robotic arm moved the tarp.
"We could tell he was alive and moving and began negotiations that way and over a long period of time we were able to get him to surrender," Watertown Police Chief Edward Deveau told CNN's Wolf Blitzer.
Authorities have said Tsarnaev's injuries mainly came during Thursday night's shootout when his brother was killed. Though at this time, hospital officials are not specifying exactly what injuries he sustained.
