provide more clues. and as the vastgation continues, so too does the recovery for victims. like mark, who lost a leg in the bombing. the other leg shattered, his arms riddled with shrapnel. i was scared, because it was dark. i thought i was dead, it was over. reporter: he draws strength every day from a photo of his 5-year-old son. every time they stick me with another needle, cut me, put something, do something, ripping, changing bandages, i look at that picture. that s what got me through it. reporter: and also, carol, an update on tamerlan tsavraev, where he will be buried. many people in boston do not want him buried here. what we are being told, an uncle actually claimed the body last night. the tsavraev family wants an independent autopsy performed. once that is done, a spokeswoman from russia says the tsavraev family does, indeed, want him buried right here in boston. all right. thanks for the clarification. jason carroll reporting live
