A former Army IT specialist who owns a home five miles from a park where University of Utah student Mackenzie Lueck went missing, has been named as a person of interest, DailyMail.com can reveal.

Salt Lake City Police have been searching the home of a man they identified as a person of interest in Lueck's case, revealing they had collected evidence from the home at a press conference on Thursday.

While police declined to name the homeowner, DailyMail.com learned it is owned by Ayoola 'AJ' Ajayi, 31, who lists a private room inside the home on Airbnb for up to $40 a night.

Officials announced they are now searching for a mattress and box spring that Ajayi had given away for free on resale website LetGo five days ago.

Salt Lake City Police requested for the person who picked up the items to contact them, as they continue searching for Lueck.

Lueck, a 23-year-old sorority member, disappeared after taking a Lyft car on June 17 from the airport to a park located miles away from her apartment.

Ajayi was employed by the Army as an Information Technology Specialist for nearly two years before leaving in June 2016, according to his LinkedIn.

He currently works at Dell as a Senior Technical Support Analyst and has so for the past 10 months.

Salt Lake City Police Chief Mike Brown said on Thursday the male person of interest is not in custody.

Authorities have said they believe the house has a connection to the disappearance of Lueck, but declined to provided any more details.

The announcement came shortly after authorities spent 19 hours searching Ajayi's home in a middle class neighborhood on Salt Lake City's west side, with neighbors describing officers entering it with shovels and police dogs.

Police have not indicated if they suspect foul play, but said they were worried as she has missed classes and flights.

The Salt Lake Tribune reports investigators said Wednesday that Lueck was texting someone as she left the airport shortly before she was last seen and that person is cooperating with cops but is not considered a suspect.

DailyMail.com exclusively revealed on Wednesday that Lueck is a 'sugar baby' who sought out men over the age of 35 online,

The college senior's social media accounts reveal that she considered herself a sugar baby, and boasted about having at least two unidentified sugar daddies which she found through online sites Seeking Arrangement and Tinder.

DailyMail.com obtained screenshots of Lueck's posts made nearly three months ago in a private Facebook group where Lueck gave advice on how she finds sugar daddies - wealthy older men who lavish younger women with gifts and money in return for company or sexual favors.

'Try tinder and be blunt about it. Mine says ''I want a SD/SB relationship with a real connection.'' If [they] don't know what a SD/SB is, tell them bluntly sugar daddy and sugar baby. But if they don't know, they aren't really worth your time,' Lueck's comment reads.

'Set your age preferences from 35+. You'll have the most luck there. Private message me, if you have more questions! I have experience.'

In another message Lueck revealed she has two sugar daddies and which sites she uses to obtain them.

'I have some experience on seeking arrangements, online only, tinder, and currently have two lol.'

About three months ago Lueck wrote these comments in a private Facebook group offering advice on how to be a sugar baby, 'Try tinder and be blunt about it. Mine says ''I want a SD/SB relationship with a real connection'''

Aside from her personal Instagram, Lueck also operates an alias account under the name @NovaBaby96, with a profile photo that shows a woman in panties that read 'Daddy' on the back.

This comes after Lueck's friends came forward to police to say she was casually dating several people and was interested in older men. Authorities didn't specify if they've spoken with anyone she was dating.

On Tuesday, Salt Lake City police shared images of her at the airport retrieving her luggage, which showed Lueck with her hair in a bun wearing a white hooded sweater, black pants and sandals.

She carried a large blue handbag with her, a small black backpack and a wheeled brown suitcase.

During a police update press conference on Tuesday, Assistant Police Chief Tim Doubt said they're looking into her social media and dating profiles.

'In regards to her online activity, we are aware of this aspect and continue to look into all facets of her life for leads into her disappearance,' Doubt said.
