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

Don’t worry, 2020 will not be the year a massive asteroid will hit the Earth. But astronomers will still have their eyes to the sky this weekend when asteroid 163348 (2002 NN4) will glide 3 million miles past Earth on Saturday. The asteroid is roughly the size of the stadium, with a diameter of 1,100 feet. The asteroid will whiz by the earth at a distance of more than 10 times further than the orbit of the moon. The asteroid poses no threat to Earth, or any spacecrafts. 163348 is one of thousands of near-earth objects NASA tracks. The objects range from the size of automobiles to over a kilometer in diameter. The vast majority of these objects are smaller. But even smaller objects can be damaging on a local level. In 2013, a 60-meter-wide meteor entered the atmosphere over Chelyabinsk, Russia. The resulting airblast caused a number of injuries due to broken windows. 891

Eleven people have died so far in 2019 while climbing Mount Everest, a behemoth of a mountain that towers 29, 029 feet above sea level. This is more than twice the number of people who died climbing Everest in 2018, which saw only five deaths that season.But it's not the number of deaths that some may find shocking — it's the reasons behind them. Only two of this season's Mount Everest deaths can be attributed to falls.So what's killing climbers ascending the mountain? It's primarily exhaustion and altitude sickness, and something called "the death zone."Seasoned climbers call any part of the mountain above 26,000 feet "the death zone" because there is only so long a human can survive at that elevation due to lack of oxygen. "Even when using bottled oxygen, supplemental oxygen, there's only a very few number of hours that we can actually survive up there before our bodies start to shut down," mountain guide Adrian Ballinger told CNN. And, unfortunately, the wait at the summit of Mount Everest plays a role in these deaths because the longer someone is at that altitude, the more severe they feel the effects from lack of oxygen and exhaustion. During the week beginning May 20, crowds of climbers became stuck in a queue to the summit. When this happens, climbers aren't eating, drinking or sleeping and continue to use up vital oxygen, which can lead to death.British climber Robin Haynes Fisher was one of those who had warned of the dangers of overcrowding."With a single route to the summit, delays caused by overcrowding could prove fatal so I am hopeful my decision to go for the 25th will mean fewer people. Unless of course everyone else plays the same waiting game," he wrote in a captioned Instagram post on May 19.He died after suffering from what appeared to be altitude sickness at 28,215 feet, while returning from the summit on Saturday.Altitude sickness occurs when people are at high elevations for an extended period of time. It can happen anywhere that's 8,000 feet above sea level or more. There are three types of altitude sickness. From least to most severe, they are: acute mountain sickness, high-altitude pulmonary edema (HAPE) and high-altitude cerebral edema (HACE). The symptoms for all three types are similar (headache, fatigue, dizziness, nausea, vomiting, shortness of breath), but HAPE is accompanied by a buildup of fluid in the lungs and HACE, the most severe type of altitude sickness, occurs when there's a buildup of fluid in the brain.So how can climbers avoid the same deadly fate as the 11 who died? Simply put — be careful. Acclimate as slowly as you can to increased elevations, drinks tons of water, rest and immediately start descending if you feel symptoms of altitude sickness.CNN contributed to this story. 2782
