On the evening of July 18, 2018, Mollie Tibbetts set out for her daily run.
The 20-year-old would never return home.
Mollie, a sophomore from the University of Iowa, lived in Brooklyn, a small town of just 1400 residents.
According to the Washington Post, when the keen runner didn’t turn up to her job at a local daycare centre the next morning, her concerned colleagues called her boyfriend of two years, Dalton Jack.
Dalton hadn’t heard from her either.
Dalton then called her family and together they contacted the local police department and reported the psychology student as missing.
Within days, a massive search was underway in the local area and Mollie’s disappearance had made international headlines.
Hundreds of people from the small town volunteered to scour the area, looking for any trace of Mollie. Five days later, the FBI and state investigators took over the investigation.
They soon discovered the last time Mollie was seen alive was two days before she went missing.
The Brooklyn native had been staying at Dalton’s house, and looking after his dogs, while he worked at his construction job 80 kilometres away.
He left for that job at 5am on July 16.
On the day of her disappearance, Dalton received two messages from Mollie – one text message and one Snapchat message.
The next morning, Dalton sent Mollie a message saying “good morning”, but never heard back from her.
Police quickly ruled out Dalton as a suspect in the case.
