Second guy on left with bad arm (white hat suspect - same hair, nose, beard, and weird arm). Saudi suspect little guy in center. Other guy unknown, but feel free to look at pic for other clues.
I think suspect #1 is crouching guy in front row in Facebook photo with white V neck T ( same kinda shirt in FBI photo)
He is a bigger guy and has similar sideburns
“Second guy on left with bad arm”
He looks nothing like Suspect #2 in the FBI photos, who looks Person or Lebanese, and if you study the FBI videos carefully, Suspect #2 appears to have a normal left hand and arm, and indeed is using his left hand to operate a cell phone in one of the photos.
White cap holds the phone in that hand (his left) to make the call. In the phone call picture, there doesn’t appear to be anything wrong with that hand.
