it's really weird watching a doc about the killings and trial... there is no mention of forensics of any kind. 2 guys blow their parents away with shotguns, call 911 and then sit on the curb and talk to the cops... seems like they would literally be covered with blood splatter, brains etc... no mention of gunshot powder residue on their hands ... after the CSI generation crime solving... just weird...
