Lueck, a 23-year-old student at the University of Utah, was reported missing[1] and her bound, burned, and buried remains were later discovered.

[4][5] In October 2020, Ajayi pleaded guilty to Lueck's murder and was subsequently sentenced to life in prison without parole.

She then attended the University of Utah where she majored in kinesiology and pre-nursing and was a member of the Alpha Chi Omega sorority.

Lueck worked at a Salt Lake City biological testing company[9] and planned to have a career in health sciences, speaking to advisors about going to nursing or medical school.

He formerly studied at Utah State University but was barred from campus in 2012 for several reasons, including problems with his visa and allegations that he had stolen an iPad.

[6][7][11] According to a contractor, in April 2019, Ajayi asked him to build a secret soundproofed room under the front porch with head-height hooks on the wall and a fingerprint scanner for entry.

[13] Prior to murdering Lueck, Ajayi sexually assaulted a woman whom he had met on a dating app and invited to his residence.

[7][13][15] On June 17, 2019, in the early morning hours, Lueck arrived at the Salt Lake City International Airport from California.

[2] An autopsy found that the blunt force trauma to the left side of her skull caused brain hemorrhaging that ultimately killed her.

[21] According to District Attorney Sim Gill, the evidence suggested that Ajayi murdered Lueck to see what it felt like to kill.

[6][7][16][20] On June 20, Lueck's father called the Salt Lake City Police Department to inform them that no one had heard from her since she arrived back in Utah.

[16] On June 28, a Salt Lake City man, identified as Ayoola Ajayi, was arrested and charged with the kidnapping and aggravated murder of Lueck, along with desecration of her body.

Neighbors reported that Ajayi had bonfires behind his garage on June 17 and 18 that resulted in a “horrible smell.” Additionally, charred fabric and other items were found in a nearby alleyway.

[16] The trial for Lueck's murder was originally set for March 12, 2020, but was postponed so that prosecutors would have more time to go through evidence and give it to Ajayi's defense attorneys.

[21] On October 7, 2020, Ajayi pleaded guilty to first-degree aggravated murder and third-degree desecration of a human body in connection with Lueck's death.

In exchange, prosecutors dropped charges of aggravated kidnapping and obstructing justice and removed the possibility of the death penalty.

[21] Ajayi pleaded guilty to one count of second-degree forcible sexual abuse in connection to this case on October 7, 2020.

[14] These charges came about in August 2019[29] after police also say that they found "numerous pornographic photos of children on his computer as they investigated Lueck’s death"[14] on July 2.
