Cherry, I am so sorry this happened to your neice. It is obvious that she held a special place in your heart and I hurt for your loss.
So the ex passed a polly and suplied an alibi. Do we know what the alibi was? He was supposedly at work (although I was of the impression he didn't work) We know it satisfied LE but do YOU know what alibi he provided? Also, do you have any more info regarding the new (current at time of murder) BF? Just approx 7PM You say he was jealous type but that Lacey never mentioned abuse by him. Correct
Also, you mention that she grew up in the cornfields of IL in your radio interview, may I ask where? Grant Park, IL I ask because I am in central IL (corn country). you also say she was fluent in spanish. That made me wonder if she grew up in or arround the beardstown area. I know that that area has a large population of immigrants from Mexico. you say that the ex BF was quite a bit older than Lacey, I wondered where they met, how long she had resided in justice, etc.
Lacey met her son's father while working at my brother-in-laws restaurant in Crete, IL called Vic's on Main. He was a busboy.
ETA I realize that these are all questions you may have answered several times previously and I apologize if I am asking you to repeat things you already said when the case was fresh but your thread and opening post called out to me and I want to give this a try. Please know I am by no means a supersleuth and have only been a member a while, but for some reason, Lacey, you , her little one and this case spoke to me and I would like to try to look at it with fresh eyes.
