Yes, thanks I know the timeframe she left party and the messages to/from her phone, what I am questioning is why the time she left the party can't be narrowed down.
She only lived 10 mins away and her friend may not have kept track of the time (which is understandable) however, she did call her to make sure she arrived home safely. We don't know what time the friend called Samantha, but it must have been shortly after she left. If the friend checked her own phone to see what time/s she called Samantha we should get a more accurate time for when she left the party.
The 1:10 call (saying she was having fun) would indicate to me that she was still at the party at 1:10 which is outside the timeframe we have been given.
Either she was having fun somewhere else, or she was still at the party. I'm leaning towards her still being at the party.
