Her phone....
She'd been talking on it.
Perhaps he was cruising for a victim....
Perhaps he saw her and circled a couple blocks....
Perhaps he parked a block or two ahead....
A matter of gross serendipity that her phone call ended mere moments before evil crossed her path, in the shape of a man but really a sick, demented human being.
What caused her phone to click off? And so quickly?
I can picture a car with the hood up, the boot open. Not threatening, just a poor bloke whose car had broken down. Untimely. Speculationing: Say, Miss, I don't mean to trouble you. Could I use your phone to call my wife?
Some people alarm us, some set us at ease. Perhaps he set her at ease with purpose. Lulled her, enlisted her help, preyed on her natural kindness.
And then.... he turns her phone off, bundles her in the back. Two minutes, tops. May well remove the sim card before he even drives away.
My sad guess, there's a digital trail of Sarah's steps that night, all indicating forward progression toward home. Until the point at which she should appear next but didn't. And within that snippet of time, only a car or two passing this way or that.
That alone would tell a story, provide a basis for a kidnapping charge....
And here we are.
Tragic ending. So brutal, so unfair.
My heart goes out to Sarah's family, friends, boyfriend. This is just atrocious. One sick, selfish actor deciding he can rewrite the story of another person's life. Stealing her from those who loved her best.
Worldwide, we weep with you.
