This (below) was not normal imo esp that AJG was not with a larger mixed-age group (incl his peers) when he was with Maddy. He was winning her trust, in a sense grooming her. He was alone with her. It's a red flag:
Male Teen: "I'd seen them together literally dozens of times, behind the building, playing, having a good time..."
This was a longer interview of what appeared to be an older male teen (face not shown) that I saw this morning. It's no longer on the site.
In the longer version, the teen adds, and I'm paraphrasing this piece now: the only thing that was a little odd was the
difference in their ages
Yup
He also said that Maddy appeared very happy and that AJG was not aggressive during those times he saw them playing together behind the building.
