I agree on all points and more:
1. Finnerty was IDed in a bad lineup.
2. He doesn't match the descriptions.
3. If the cops did not include him earlier it was probably because he did not match her descriptions.
4. Later Mangum probably was coached illegally to pick him due to the charge pending against him in DC.
But factually he is the only one of the three who was IDed the first time she was him apparently.
That is unfortunate for him. Hopefully the lineup she picked the three of them from will be tossed. But I must say due to this point, his prior in DC, etc he might be passing Evans as the one in most danger. Thankfully rumor has it that he has a alibi.
I would hate it if any one of these guys had no alibi, was picked by her the first time she saw him and could not be excluded from the DNA on the nail. Fortunately, that is a combination Evans/Finnerty and no single person has that much against him here.
It's wonderful for Collin if she couldn't have seen him at the party.
