>> latest on the conditions of the surviving suspect, dzhokhar tsarnaev. ron allen is outside of the boston hospital where he is being treated. ron, what's the latest from there?
>> reporter: good morning, lester. we're not hearing anything officially from the hospital staff here. they are deferring all questions to the fbi because this is of course an extremely sensitive manner. we believe he's in serious condition. we believe he was wounded at some point in the process because the man who found him found him under a tarp covered in blood was the way his condition was described then. sources have also told us that he has lost a lot of blood and that he was somewhat incoherent when he was found by authorities and captured by authorities. he's 19 years old. he's been american citizen who ironically became a citizen on september 11th of last year. a student at a branch of umass dartmouth not far from here where he was studying marine biology . the family came here ten years ago from southern russia and appears that he was something of an introvert. there are a number of family members who indicated as much. the bottom line is that he's now here at the hospital being attended to. we hope to learn more about his condition in the coming hours and at some point he will be charged we expect with four counts of murder and a lot more. lester?
