20-year-old Mollie Tibbetts loved to run.
It was her way to unwind.
The time in her day when she could shut out the rest of the world.
The evening of July 18, 2018, was no different.
Mollie laced up her shoes and put her phone on Do Not Disturb.
And off she went.
Running through the streets of her hometown, Brooklyn, Iowa.
Her phone told the story.
She was keeping a 10-minute-mile pace.
Until she stopped.
And then her pace picked up again.
Way up, to 60 miles an hour.
To investigators, that meant Mollie wasn’t running anymore.
Would they be able to find her before it was too late?
