Looking at the photos released from NYPD, these are the ones I see as new. As far as I can tell, there are no new people in them, however, some do show other background persons, such as the Five Spot Club pictures show a couple of men. Also, some of the pictures show more of the backgrounds than we have seen. Here are the ones I thought were significant:
Girl with Peach Blouse at table, picture #23,133, 84.
Brunette with Headphones on #27, 32.
Girl with Turban on #34, (looks drugged here to me) &72
Five Spot Club girls, #42, appears to be a curly haired man in here, and #95 another man appears, 148 & 157
Young man with long dark hair: #66, & 87.
Girl with Crocheted Orange Bikini: #75
Frizzy Haired Girl #81 (she has a tambourine in this picure)
Girl with Herringbone Jumper #99, I think that's a new one, I don't remember seeing her earrings that well.
Desert Girl Picture #100, 193
Long Red Haired #107, shows more of the room
Bare midriff girl by window #114
Blonde girl with Bangs and strange eye #136
Young boy on bike #150 and 162, shows his teeth, and some are missing.
Long haired girl in white sweater 155
Yellow shorts girl, 171, sticking out her tongue
Here's the scariest ones to me, I guess just because there's so many. Young short-haired blonde girl: 112, 118, 130, 134, 142, 152, 164, & 173.
Maybe housekeeping or someone better at it than I am, can put these pictures where they belong.
