Twelve days after the disappearance of University of Utah student, Mackenzie Lueck this summer, and following an exhaustive investigation by law enforcement, police arrested and formally charged the suspect in her death, Ayoola Adisa Ajayi. Ajayi faces four charges in connection to Lueck's violent murder, including aggravated murder and aggravated kidnapping. KSL Investigators knew Ajayi was the person of interest in this case because he owned the small property in Salt Lake where multiple search warrants were executed in the case prior to his arrest. Before authorities released his name to the public, KSL Investigators worked to learn everything they could about the 31-year-old immigrant, originally from Africa, so we could break the investigation as soon as the suspect's name was released. Although much of a person's immigration status is private information, representatives with the Salt Lake County District Attorney's Office confirmed Ajayi is a lawful legal resident and he was at the time of his arrest. However, the KSL Investigators exposed how he came to this country and revealed possible oversight by Utah State University and the federal government when he dropped out of school a number of times and was posting online about seeking to find a wife to keep his citizenship status.
