Total lack of any sightings after she supposedly walked out the front door.
Statements from her family that she wouldn't walk to the shops alone, extremely shy etc.
Sudden lack of online activity / phone usage.
She hadn't taken spare clothes and left purse so not a run away.
Texts planning to meet boyfriend later in the day.
Was also stated that if she had plans she'd of just gone but would have let us know at some point. I think the shy/introvert has been pushed to silly levels.
