Cellphones and social media were at the heart of the investigation that led to an arrest in the killing of a University of Utah student who vanished nearly two weeks ago.Investigators tracking her cellphone discovered that 23-year-old Mackenzie Lueck and the man expected to be charged with her murder were both in the park where she was last seen on June 17 within a minute of one another.That was around the time Lueck's phone stopped receiving data or location services, police said.Ayoola Ajayi, 31, was arrested Friday and is expected to be charged with aggravated murder. He also faces charges of aggravated kidnapping, obstruction of justice and desecration of a body, according to Salt Lake City Police Chief Mike Brown.Police find her pictures on his phoneAfter Lueck disappeared, the suspect originally denied knowing what she looked like, Brown said. But several pictures of her were found on his phone, and the "digital footprint" has continued even after the arrest, police said.An Instagram account that Lueck's sorority sister confirmed belongs to the missing student followed another user on or about Wednesday, CNN verified.Brown confirmed that investigators are looking into the activity on the account."This is a digital forensic investigation," he said. "This is covering computers, cellphones, IP addresses, URLs, texting apps."Forensic evidence is also discovered But the investigation is not just limited to digital footprints.Investigators also found forensic evidence after they searched Ajayi's home and property Wednesday, police said. As they did, his neighbors told police they saw him using gasoline to burn something in his backyard on June 17 and 18, Brown said.Police said the search yielded multiple items of evidence."A forensic excavation of the burn area was conducted, which resulted in the finding of several charred items that were consistent with personal items of Mackenzie Lueck," Brown told reporters.Police also discovered charred material that was determined to be female human tissue consistent with Lueck's DNA profile, he said. A mattress investigators have been trying to find has been located, police tweeted Friday night, without providing additional details.She stopped communicating about 3 a.m. Lueck texted her parents at 1 a.m. on June 17 when she landed at Salt Lake City International Airport, police said. She was seen on airport surveillance walking through baggage claim before taking Lyft to Hatch Park.The Lyft driver said she did not appear to be in distress, according to Salt Lake City police assistant chief Tim Doubt.Police said Friday that all communications with Lueck's phone ceased around 3 a.m. that morning -- the same time they said she left the park with the suspect.Phone records showed her last communication was with the suspect, Brown said. Her family and friends did not see or hear from her after that morning. Her sorority sister told CNN affiliate KSL that Lueck had also missed exams."She's extremely dedicated," Ashley Fine told the TV station. "She would never miss her midterms or anything like that. She hasn't been home. She didn't show up to work, or anything."A suspect is arrested After the suspect's arrest Friday, Brown contacted her parents to tell them the news. They were "devastated and heartbroken by this news," he said."This is one of the most difficult phone calls I've ever made," he said.The suspect lived about five miles from the park where Lueck was last seen.According to his LinkedIn page, he is a former information technology specialist for the US Army and recently worked for Dell and Goldman Sachs. CNN has reached out to the US Army and Dell for comment. 3686

DENVER, Colo. – Buying a Christmas tree can represent the start of the holiday season. But trees can be expensive. If you want it to last until the big day, there are simple steps to take when buying the perfect tree.Doug Brown is the owner of Reindeer Ranch in Denver, Colorado. He’s been selling Christmas trees since 1997. So, he knows a thing or two about what type of Christmas tree lasts the longest.Brown says, "the noble firs and the Fraser firs tend to be the Cadillacs of trees. Those are going to be the ones that give you the best look and the most longevity."When picking a tree on the lot, Brown suggests doing the touch and smell test. If no needles fall off and it smells like pine, it’s a healthy tree.As for the price of the tree, this year you might be paying a little extra.Brown says, “we are in a tree shortage right now." That means the demand outweighs the supply. Before you leave the lot, make sure you get a fresh cut on the bottom of your tree. That way it soaks up all the water when you bring it home.Once your home Brown says, "get it into your stand and put water in it right away no longer than 6 to 8 hours."Make sure to check the water daily. A tree drinks about a gallon of water a day.Also, never place your tree next to a vent, fireplace or window because that will dry out the tree. There’s also no need to put fertilizer or Miracle Grow in the water.Brown says, if you follow these simple tips, you and your loved ones will be enjoying your perfect tree the entire holiday season.Brown is not only selling trees this year. He is also holding a toy drive too. On Saturday, December 14, they will be giving away 200 toys to families in need. The toy drive starts at 10 a.m. 1723

DENVER, Colo. – Workers use a lot of masks at Comfort Dental in downtown Denver.“We order about 12 boxes a month and each box has 50 masks in it,” said Dr. Jashon Hughes.Now, Hughes and his staff are experiencing a major shortage with this much needed medical supply, saying this deficit is linked to increased concerns over the novel coronavirus.Following news of the coronavirus spreading, Hughes started seeing companies putting a limit on how many masks he can order.“Usually I can order as many boxes as I wanted,” he said while looking at an online order form. “It says, ‘due to the coronavirus outbreak we are experiencing higher than normal demand globally for infection control products such as masks, goggles and face shields.’” Now, other medical experts are speaking out on this shortage. “I can understand why folks want to wear masks,” said Sheryl Zajdowicz, Ph.D. “However, it’s really a bit of a panic move.”Zajdowicz is a biology professor at Metropolitan State University of Denver and says most times wearing a mask won’t keep people protected.“You may not have any benefit whatsoever,” she said. “Because you may be wearing it long term, getting it saturated and that could possibly make you more susceptible to contracted other things.” The U.S. Surgeon General recently urged the public to stop buying masks and leave them for health workers, tweeting “they are not effective in preventing general public from catching coronavirus, but if healthcare providers can’t get them to care for sick patients, it puts them and our communities at risk!”Zajdowicz has also noticed some people trying to make a profit and cash in on this concern with the coronavirus with hand sanitizers selling for several times more than its normal cost.“It seems a bit extreme and just appalling to see that cost,” she said. “ for a typical bottle (for an right-ounce bottle of hand sanitizer).”Zajdowicz says the best defense against the coronavirus is a good ol’ fashioned handwashing – scrubbing your hands with soap and warm water for at least 20 seconds, which is about the time it takes you to sing “Happy Birthday” twice.Back at the dentist's office, Hughes says the super high demand for masks is creating all kinds of challenges.“Coronavirus isn’t the only thing hoping to protect from,” he said. “We’ve got the flu, colds, stuff like that.”He added if the concerns continue to grow and supplies continue to shrink, they may have to take drastic measures to stay safe“Long term if this thing blows up then, yeah, you could see offices not opening here and there if it did spread and get worse,” he said. 2625

DETROIT — A flyer distributed around the west side of Detroit is causing concern. Is it racist? Is it real? Is it reversing Detroit's history?The flyer is an advertisement for a community discussion about "White integration into the Russell Woods-Sullivan area." The neighborhood has been majority black for years, but gentrification has recently brought more white people to the area. Rhonda J. Smith organized the meeting and wrote the flyers. She says she chose the wording deliberately to hit some nerves. She's lived in the Russell Woods-Sullivan neighborhood for more than 20 years and is seeing a change with more white people moving into homes."I was tired of hearing the same story about the white gentrifiers and the black victims," Smith said. "I wanted to see if there is another angle I can approach."She's a fellow with the Detour Detroit online newsletter.Smith says some of her black neighbors have complained to her about new white residents walking their dogs and messing up their yards. And another neighbor said they are coming in and taking over, but they didn't exactly say what that means.Race is always a hot issue in Detroit. "White flight" happened for decades in the city. This neighborhood is not far from where the 1967 riots broke out.This story was originally published by Jim Kiertzner on 1333
