Just wanted to share what seems to be a much clearer photo of Suspect #2 than what's shown in the FBI video (this photo has since been featured on Piers Morgan - warning: the full image below is a bit graphic):

If you zoom in center left, you'll see Suspect #2 more clearly - to my eyes anyway (zoom crop here):

(Thanks kyril for the edit)
Or zoomed even more (thanks BvueDem):
At the risk of stating just my opinion, I'd describe him as a short, thin, Caucasian/Semitic? male with a distinctive nose, dark hair. He looks young and from that shot I imagine anyone would recognize him.
Just wanted to share since I couldn't make heads or tails from the FBI video and this photo seems to clearly show Suspect #2 in more detail - despite the "only official photos welcome" warning and all that.
Let's make sure as many people as possible see this photo.
Tip for great justice and let's get the bastards!
