UPDATE | Missing college student was killed, man arrested

SALT LAKE CITY (AP) — A college student who went missing 11 days ago after last being seen in a Salt Lake City park at 3 in the morning was the victim of a kidnapping and homicide, authorities said today.

Salt Lake City police chief Mike Brown said Ayoola A. Ajayi will be charged with aggravated murder, kidnaping and desecration of a body in the death of 23-year-old Mackenzie Lueck. He was arrested earlier this morning by a SWAT team.

Brown said he told the missing woman's parents in Southern California about the arrest earlier this morning.

"This is one of the most difficult phone calls I've ever made," Brown said. "We are devastated and heartbroken by this news,"

Police say Ajayi, 31, met Lueck at the park after taking a Lyft from the airport at 3 a.m. It was not immediately clear how or whether the two had known each other previously.

Brown says burned evidence, including Lueck's things and her remains, was found at his home. The home was searched Wednesday and Thursday and Ajayi was the man previously identified as a person of interest.

It wasn't immediately clear if Ajayi had an attorney. He has not returned previous messages from The Associated Press.

SALT LAKE CITY (AP) — One person was taken into custody today in the case of a Utah college student who disappeared 11 days ago, police said.

Officials did not immediately provide further details ahead of a planned news conference scheduled later today in the disappearance of 23-year-old Mackenzie Lueck.

The news comes a day after police finished a nearly daylong search using shovels and dogs in their search of a home belonging to a man they called a "person of interest" in the case. Investigators have also been searching for a mattress given away from the home last week.

They also took a vehicle from the home. Police have not specified his connection to the case.

Online court and property records identify the man as 31, divorced this year and with no criminal record in Utah. The Associated Press is not naming him because authorities have not done so.

Lueck disappeared after taking a Lyft June 17 from the airport to a park. Police said she met an unidentified person there at 3 a.m., and did not seem distressed.

Authorities have said the Lyft driver had no connection with her disappearance. The home that police searched Wednesday into Thursday is about 5 miles from the park.

Lueck is a part-time student at the University of Utah in her senior year majoring in kinesiology and pre-nursing. She has been a student since 2014 and has an off-campus apartment.

She is from El Segundo in the Los Angeles area and flew to California for a funeral before returning to Salt Lake City, police said. Her family reported her missing on June 20 and became more concerned after she missed a planned flight back to Los Angeles last weekend.
