Yes to both. ABC has confirmed time and they were discussing him being followed. She heard the conversation and the beginning of the struggle.
If she heard the beginning of the struggle why wasn't she more concerned about it?
Why didn't she try to call back T?
Why didn't she call his parents or police?
Was she not concerned enough to try to reach T later because the struggle was business as usual with T?
I read the story about T's father not knowing about his son's whereabouts till the next morning. Even he called the police to check if T was arrested. IOW, they all knew T was not the angel the media portrays him to be.
