Yes. As the detective said Holly was never seen in the restaurant on their cameras and none of her co-workers had plans to have lunch with her despite the story he told of her allegedly having lunch with co-workers. This is a changed story from the original that had been given where he allegedly dropped her off and then forgot to pick her up.
It seems quite a few people were aware of what was going on between Holly and Cody. Also, it had been said that Holly's husband had been aware of Holly being pregnant but that wasn't brought up at all in the episode and I was hoping to learn when he had known.
I am curious if Cody's wife knew what was going and if she did was she also aware of Holly being pregnant.
At any rate, LE hung out Cody as a named person of interest but made no mention of her husband as a person of interest despite the push in that direction by her family.
