The anguished mom of missing student Mollie Tibbetts has revealed perplexing new clues about her daughter's mysterious disappearance two weeks ago - telling DailyMail.com: 'I'm in purgatory.'
University of Iowa sophomore Mollie, 20, was last seen on the evening of July 18 when she went jogging in her rural hometown of Brooklyn.
In the past two weeks investigators have completed 200 interviews, fielded hundreds of tips and carried out painstaking fingertip searches of the vast cornfields surrounding the close-knit farming community, an hour east of De Moines.
But without a single credible lead pointing to her daughter's whereabouts, Laura Calderwood, 54, added: 'I'm either going to be headed up to heaven or down to hell, depending on the result.'
Psychology major Mollie was dog-sitting at the home of her construction worker boyfriend Dalton Jack, 20, when she set off for her evening run around 7.30pm.
He says his last contact with his girlfriend of three years was a Snapchat message he opened at around 10pm.
Still missing: Mollie Tibbetts, 20, was dog-sitting at her boyfriend Dalton Jack's home in Brooklyn, Iowa on July 18 when she went for a jog and vanished
A mother's anguish: Mollie's mom Laura Calderwood, 54, told DailyMail.com that her daughter's disappearance has left her 'in purgatory'
Mollie was last seen jogging on West Pershing Drive by a neighbor around 7.30pm on July 18. Her boyfriend, who was staying 120 miles away in Dubuque, opened a Snapchat from her at 10pm
The next morning Mollie failed to show up to work at Grinnell Regional Medical Center located 15 miles from her home. Her family then reported her missing to police
Jack thinks it was taken indoors at his house but told DailyMail.com he couldn't be sure because the message expired ten seconds later.
DailyMail.com understands that the tech giant Snap Inc. may not be able to retrieve the content of the 'snap' because it wasn't saved.
Investigators do, however, have access to data from the Fitbit device that high school cross country competitor Mollie used to monitor her runs.
The fitness accessory is one of a number of items search teams are still desperate to find, including Mollie's clothing, her gold colored iPhone7, earbuds and an armband.
Her car, a wallet containing a driving license and debit card, and an unused passport, have all been located, according to Laura - who says it's 'inconceivable' her daughter skipped town without saying a word.
Investigators are so far refusing to say whether or not Mollie made it home from her jog, with conflicting evidence suggesting she may have gone missing later that night or even the next morning.
When she failed to show up her at her summer job at a daycare center on July 19, friends and family raised the alarm.
And despite nationwide media coverage there have been no arrests nor confirmed sightings to date.
'Every time I try and form an opinion there is a piece there that doesn't fit into the puzzle,' a confounded Laura told DailyMail.com.
Laura (pictured with young Mollie and her brother Jake) says it's 'inconceivable' that Mollie skipped town without telling anyone and has 'braced herself' for the possibility that she was abducted
Authorities have not named any suspects in the case so far, despite conducting more than 200 interviews
She admitted she has 'braced herself' for the possibility Mollie was abducted – but added: 'My faith is strong and the conviction to find Mollie gets a little bit stronger every day.
'The focus is on finding her. Everyone is working together to get her back safely.'
Mollie is 5ft 3in tall, weighs about 120 lbs and has long brown hair and brown eyes.
Anyone with information about her is urged to contact the Poweshiek County Sheriff's Office at 641 623 5679 or email [email protected]
Tips can also be submitted via Crime Stoppers of Central Iowa which has collected $172,000 so far in donations that will be available as a reward for information leading to Mollie's safe return.
Crime Stoppers can be contacted anonymously at 1-800-452-1111 or via their website.
LACK OF SUSPECTS
Mollie was staying overnight at the home of her boyfriend Dalton Jack but he was 120 miles away in Dubuque, Iowa working for a construction firm.
Investigators say they have ruled Jack out as a suspect and Laura Calderwood insists he's above suspicion.
'He's a good guy. They were devoted to one another,' she told DailyMail.com.
Jack lives with his 23-year-old brother Blake Jack and Blake's fiancée, Allie Houghton, 24, who were also out of town.
Tibbetts had been staying at her boyfriend Dalton Jack's (pictured) home in Brooklyn while he was working a construction job 120 miles away. He said he received a Snapchat from her that night
This is the home where Mollie was last thought to have been when she went missing. Brooklyn residents typically do not lock their doors, but her mother does not believe she returned to the home after her jog
Police photographed the inside of Wayne Cheney's home, took his cell phone overnight and took him away from the property to be questioned
Mollie's mom is estranged from her father, Robert Tibbetts, 59, who lives in Oakland, California and flew into Iowa after she vanished to help search for her.
With family and friends in the clear, investigators looked at registered sex offenders and convicted criminals living locally.
Wayne Cheney, 56, lives in a trailer home about 500 yards from a pig farm that was searched by investigators eight days ago.
Wayne Cheney, a man with stalking convictions in 2009 and 2014, lives in a trailer home about 500 yards from a pig farm that was searched by investigators eight days ago.
The 56-year-old told DailyMail.com he sold the facility to Prestage Farms five or six years ago.
He said he had never met Mollie or her family.
When asked about his previous arrests, he said: 'I was arrested in 2011 for breaching a restraining order. It was an ex girlfriend. That was the only time.'
Cheney then terminated the interview abruptly and went back inside his one-story, trailer home in Deep River, 15 miles south of Brooklyn.
Calls to Prestage Farms were not immediately returned.
The search yielded nothing and Cheney told the TV station he didn't know Mollie or her family but hoped she would be tracked down soon.
Police in Dubuque meanwhile quizzed a suspect in an assault on a female jogger on Sunday while another man was questioned in Pella, an hour from Brooklyn, after he was spotted taking covert photos of girls.
However, neither individual has been linked to the hunt for Mollie and cops say they are yet to identify a suspect.
Authorities have also said a reported sighting of Mollie at a truck stop in the Kansas City, Missouri area late last month, was not her.
THE FITBIT FOOTPRINT
One of the key questions for investigators is establishing the route Mollie took on her run and whether she ever returned home.
Laura Calderwood said her daughter ran for about 45 minutes every evening, varying her route through the town's pretty rural trails and cornfields.
Almost every store and vehicle across the Iowa town of 1,413 people is adorned with the now-recognizable photo of a carefree, smiling Mollie, along with a plea for information

She left Dalton Jack's four-bedroom home in West Des Moines Street and was last seen by a neighbor, Nate Hopwood, who lives a few hundred yards away in West Pershing Drive. From there the trail goes cold.
The FBI has gained access to Mollie's Fitbit which typically tracks the number of steps a user has walked, their heart rate, quality of sleep, steps climbed and other fitness metrics.
If she had a more advanced model that hooked up wirelessly to her phone's GPS it's possible they could glean the exact route.
Authorities have said they are tapping into all the electronic tools at their disposal to access data on Mollie's phone, social media accounts and email.
'I know they have subpoenaed Google to gain access to three different email accounts she used,' Calderwood told DailyMail.com.
Snapchat COULD BE LOST FOREVER
Dalton Jack glanced at his Snapchat account at 10pm on July 18 and noticed a 'Snap' from Mollie.
He remembers seeing her face and a brief caption along the bottom of the screen - but says he can't recall what it said.
Jack told DailyMail.com he thinks it was taken indoors at his home but admits he cannot recall any particular identifying features in the background.
