Suspects one and two leaving the area after the blast. 2 is going around the corner lower left, 1 is back up the sidewalk a bit near the woman in pink.
Didn’t know if posted already. No time to read whole thread, but wanted to get it out there.
Blew this up as big as I could. The person you say is the second guy is NOT him. Red coat, black and white scarf, mustache and appears to be with the women.
