This week, an arrest was made in a 20-year double murder case gone cold. The victims were two 17-year-old Alabama girls. The big break for police: results from a DNA ancestry test. Police arrested 45-year-old Coley McCraney through genetic genealogy, which used his DNA to find relatives. Investigators say they were inspired by the arrest of the Golden State Killer back in April, when police used genetic genealogy to link 72-year-old Joseph James DeAngelo, to at least 13 murders and more than 50 rapes in California during the 70's and 80's. Police used that same technology to arrest men responsible for other unsolved cases that dated back to the 1970’s. "Well over the years, you think about it all the time. I don't think that ever leaves anybody that was working then. It never left your thoughts,” says retired Newport Beach Police Officer Stan Bressler of unsolved cases. So, how are police able to use genetic genealogy results to solve these cases? “We get DNA from a crime scene,” says Ellen Greytak of the first step. Greytak works with Parabon NanoLabs, which helped police arrest suspects in 1,000 years of cold cases. She says her company uploads the DNA to the genealogy database GEDmatch, which is separate from companies like Ancestry.com and 23andMe.“So, they have over a million people in that database and what's returned is basically a list,” Greytak explains. “Here are the people…who share the most DNA with your unknown person.” Then, genetic genealogists step in, building family trees and then narrowing down suspects based on information. “So we know where the crime happened; we know when it happened,” Greytak says. “That limits the age range. You know the person might have lived nearby, but not always.” The information is then handed off to police, who often conduct a traditional DNA match, before making an arrest. Still, some groups are concerned about privacy. However, Greytak says anyone can choose to opt out.“They choose to either set their data to private in GEDmatch, so they're not part of searches, or to take their data down. You know they have full control over that,” Greytak explains. 2151

TripAdvisor has defended itself against accusations of misleading travelers by failing to stop some of its highest ranked hotels winning their status with fake reviews.UK consumer group Which? Travel analyzed a total of almost 250,000 reviews for the 10 top-ranked hotels in 10 global tourist destinations, from Las Vegas to Cape Town. It found that one in seven of the hotels had "blatant hallmarks" of fake reviews, with others raising "serious concerns."But TripAdvisor called the analysis "flawed" and said its more sophisticated detection tools were able to weed out fraudulent feedback.Which? Travel said that when it reported 15 of the worst cases to TripAdvisor, the reviews giant -- now one of the world's biggest travel websites -- admitted that all but one of the hotels in question had been caught using fake reviews in the past year.Six had previously been penalized, and two had received a "red badge warning" -- where TripAdvisor warns users that the hotel is suspected of using fake reviews, and has "repeatedly failed to remedy its behavior and refuses to cooperate with TripAdvisor's investigators."Yet, Which? Travel said it found that the review patterns had continued unabated despite the measures, and the red badges had been removed.The group has accused TripAdvisor of a "lack of serious ongoing action to address repeated abuse of the system."It says that five-star reviews left by new users who have written no other reviews should be a red flag. Its analysis compared the proportion of first-time five-star reviews with that of first-time three-star reviews, which are less likely to be faked.In total, it studied 247,277 reviews."TripAdvisor's failure to stop fake reviews and take strong action against hotels that abuse the system risks misleading millions of travelers and potentially ruining their holidays," said Which? Travel's Naomi Leach.TripAdvisor has removed hundreds of reviews in light of the investigation, Which? Travel claimed."Striking" evidence of fake reviewsHotels in the Middle East had "striking" amounts of fake positive reviews, according to the research. TripAdvisor docked 730 five-star reviews of the "best" hotel in Jordan following the analysis -- but the hotel has not been given a red badge. It remains in the top 10 in the country.At the top-ranking hotel in Cairo, 79% of five-star reviews came from one-time contributors. Just 14% of three-star reviews came from similar accounts.The hotel has lost its status as a result of the reviews' deletion.Las Vegas was another hotspot for fake reviews. At two of the top-rated hotels, almost half the five-star reviews came from one-time contributors. For a competitor which did not arouse suspicion, the figure was just 3%.Some of the top-ranked hotels in London, Paris, Barcelona and Cape Town "gave reason for suspicion," the research showed, but failed to demonstrate the same patterns across the board.Repeat offendersTripAdvisor called the analysis "based on a flawed understanding of fake review patterns," adding that "it is simply far too simplistic to assume all first-time reviewers are suspicious."It said that Which? Travel did not have access to IP [internet protocol] information or location data, both of which TripAdvisor uses to detect fake reviews."We analyze hundreds of data points about each review -- most of which only we have access to -- and we combine that data with a wealth of knowledge and understanding of review patterns that our team of experts has gained from tracking hundreds of millions of reviews over a near 20-year period," said the company."This includes an ability to track and analyze first-time reviews in far more detail and with far more rigor than Which's team was able to do."Online reviews influence an annual estimated ￡23 billion ( billion) of booking transactions in the UK alone, according to the UK government."Sites like TripAdvisor must do more to ensure the information on their platforms is reliable," said Naomi Leach."If they continue to fall short, they should be compelled to make changes so holidaymakers are no longer at risk of being duped by a flood of fake reviews." 4152

There are many changes planned to revamp Nashville International Airport including the newly unveiled parking garage. Part of the plan is to give the airport a face lift which includes replacing the terminal carpet that surprisingly has garnered popularity.The brown carpet with its unique lines and swirly designs was installed in 2010. Earlier this year, the BNA carpet gained its own Instagram account with more than 6,500 followers and over 100 posts.Its Instagram stories is flooded with travelers tagging the account as they typically walk through the airport and show the carpet.In case you are a fan, you can purchase clothes, shoes, luggage, and phone covers with the same pattern on an online merchandise boutique called Ray Reid. The popularity also resembles the love for the iconic, retro carpet at Portland Airport before it was removed a few years ago. It also had social media accounts and countless merchandise that offered the pattern.Airport officials in Nashville are aware of the BNA carpet fame. However, it will slowly phase out by the start of the summer of 2020.By 2023, it will all be updated with either terrazzo or new (with a different pattern) carpet, according to a BNA spokesperson. The changes are all part of a bigger picture called BNA Vision. The plan will include demolishing the existing Short Term Parking Garage next month to make room for a bigger and more modern garage.Expansion is also underway for Concourse D and terminal wings, and people should start seeing visible of that in January when steel starts going up. Concourse D will add six new domestic aircraft gate, a variety of restaurants and retail options, and a live music stage. It is expected to be completed by 2020.Additionally, there will be a major renovation of the terminal lobby, which means expanding security screening checkpointsAll of the BNA Vision plan is expected to be finished by 2023. 1918

The upstart ex-spellers who launched an online spelling bee to fill the void left by the canceled Scripps National Spelling Bee had little trouble running an efficient, and sufficiently challenging, competition.Replicating the drama of the ESPN-televised national finals wasn’t quite as easy.Thursday night’s winner, Navneeth Murali, was no surprise. The 14-year-old eighth-grader from Edison, New Jersey, came in with the most extensive spelling resume of anyone in the bee. When the two other remaining spellers misspelled words back to back before his turn, victory in the closest thing to a national spelling bee in this pandemic-disrupted year was his for the taking.He didn’t back down.Navneeth went through the motions of making sure he understood everything about the winning word, Karoshthi — an ancient, cursive script of Aramaic origin used in India and elsewhere in central Asia — before he started to spell. He plowed through it quickly and confidently, as he had all night.“That is correct,” SpellPundit co-founder Shourav Dasari told the assembled spellers over Zoom, “so, yeah, you’re the champion of the SpellPundit Online National Spelling Bee.”“Thank you,” Navneeth deadpanned.Then the digital confetti fell — sort of. Shourav, a high school junior just three years removed from his own close call at the National Spelling Bee, shared his computer screen, which briefly flashed a silent, pixelated image of confetti falling. A few clicks later and he brought the confetti back, this time with fake crowd noise.The SpellPundit bee concluded on the same night Scripps would have held its grand finale inside a packed convention center ballroom on the Potomac River outside Washington. 1714
