Police searched a home that they believe is connected to the disappearance of a 23-year-old University of Utah sorority sister who went missing more than a week ago, authorities said.

“#SLCPD served a search warrant on a house in Fairpark with a nexus to the missing MacKenzie Lueck case,” the Salt Lake City Police Department tweeted late Wednesday.

Authorities descended on the home around 2 p.m. Wednesday, and remained there through the night, the Salt Lake Tribune reported. Police towed away a car from the scene.

“Obviously we are treating this with a high degree of care,” Salt Lake City Assistant Police Chief Tim Doubt said during an evening press conference, according to the Tribune. “Given the nature of this case, we just don’t want to make a mistake.”

Anyone living at the home is part of the investigation — and there is a “nexus” between the residence and Lueck’s disappearance, Doubt added. However, he would not say whether anyone had been arrested or comment on any evidence that cops may have uncovered.

The owner of the home, who has lived there for a couple years, has no criminal history in Utah besides some traffic citations, the Tribune reported.

Neighbor Tom Camomile told the outlet that the owner turned part of the home into a rental he offers through Airbnb.

“There are people coming and going most of the time,” he said.

Nearby residents also told the paper they recently spotted the owner burning something in his back yard, sending smoke billowing in through their windows.

Police also confirmed Wednesday that Lueck was texting someone from the Salt Lake City airport before she disappeared, but that person is not currently considered a suspect or person of interest, the paper reported.

Authorities could not go into detail about that person’s identity, what they texted about, whether their communication continued after Lueck left the airport or if she is known to have communicated with anyone else that morning, police spokesman Michael Ruff told the Tribune.

“Everything is still open,” Ruff said. “There is no person of interest. We just know that this is the person that Mackenzie was texting with and we have spoken to them.”

Lueck, who is from El Segundo, Calif., went missing within hours of arriving at the airport on June 17 from a trip home for her grandmother’s funeral.

The college senior called a Lyft from the airport to Hatch Park in North Salt Lake, where the ride-share driver saw her jump into another vehicle just before 3 a.m. with an unknown individual, authorities said.

Police have said they were unable to verify the make of the vehicle or the identity of the person she encountered at the park.

Investigators have been digging into Lueck’s dating apps after receiving tips that she was interested in older men and casually seeing several people.
