When one Emma says, "sometimes she wouldn't go deep in the park, she might have walked from the 12th Street entrance to the 10th Street entrance." The implication is she walked from 12th to 10th within the park. Please see attachment and outline, this is a common route and doesn't put one deep in the park.
Except we know based on evidence released to date it's unlikely she took that route that night.
She also likely didn't walk on the street from 12th street entrance to 10th street entrance (aka Charles Allen gate) since again based on camera footage released she should have visible.
It's more likely IMHO, she took one of the smaller entrances either between 10th and 11th or on 10th closer to Argonne both of which would put her on the small path which parallels 10th.
