that guy in the puffy coat is way over dressed for this time of year in NE-but the main thing I noticed is that he is wearing a winter hat-very unusual for this time of year in NE.
When spring arrives in NE the first things to go are your hat and gloves-and maybe switch to a Red Sox hat...he just looks odd to me....
To the back left of your thick yellow outline is a Chinese woman, about a row back. Third victim that died was a Chinese student.
Re ‘baby stroller’:
Plausible, but I have yet to read a comment observing the guy in the white hat that has a white towel over his right shoulder and what appears to be a baby’s being cradled in his arm on that shoulder.
Just an observation...
Look at 7 o’clock, below the woman in green sweater. There’s the soddie in gray jacket with BLACK BACKPACK. He was one of the three in first photo - with the guy wearing a ballpoint pen on his tshirt (which kinda tells me it’s an identifier for something)...
Do you see a kid in an orange baseball cap next to the girl in green? Seems like he could be the 8 year old victim. Or the older brother of the 8 year old victim. He’s in a couple of photos.
Is the woman in the brown/orange coat with sunglasses (to right of the girl in green) his mother? Also looks like a little kid is sitting on the shoulders of the guy in front of the woman. I think the 8 year old victim was with his little sister who injured and his older brother who was uninjured. Maybe the kid sitting on the guy’s shoulder is the sister (not the photo marked with “possible 8 year old victim) but in the lower right hand corner near the blond guy in yellow.
#58 and #90
In one photo he (8 year old boy) looks to be standing next to the the two suspicious guys (see dark blue square in photo #90).
