What I find strange, is that when one of their male friends left the dinner table to supposedly check on his own kids, he said he would also check on Maddie and the twins.
Therefore he was effectively the last person to see her in the apartment, with bundles of time and opportunity for wrongdoing. But nothing seems to be said about him in terms of being a possible suspect.
I'm not accusing him. (my lawyers have told me to add)
You have to assume they have eliminated him as a suspect and therefore they don't mention anything. They don't just go straight to public appeal without doing a bit of work first.
