I agree with you. I think it very possible she was at Gurnee Mills Mall which is west of I-94.Actually, we don't know where she was from noon until ten o'clock pm on Saturday. I was speculating that the Gurnee Mills Mall was not out of her way in any sense of the word, she loved to shop for her grandchildren and since it was on the way and she had the time built into her trip perhaps she had stopped there. It also satisfied me as to how that particularly obscure driveway at the big intersection only a few miles from the mall would be a final destination.
When the perp in the article said he had done it before and knew how to do it to cover a crime, it just clicked with me. And, I wondered if LE was looking into any connection.
Nothing more, nothing less.
MOO MOO MOO MOO
Good point about the NW Indiana murders. Here's a timeline and hopefully LE is investigating any connection. The NW Indiana killer is a 17-yo and the murders were brutal. He was planning on going back and picking up the burned car with a uhaul and dumping it into the Mississippi River which is several hours west.
