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

There have been 530 confirmed and probable cases of lung injury related to e-cigarettes as of September 17, the US Centers for Disease Control and Prevention said Thursday. That's 150 more than had been reported on September 11. There have been cases in 38 states and one US territory.Among the cases for which the CDC has received information about patients' sex and age, 72% are in men, 67% are in people ages 18 to 34, 16% are in people younger than 18 and 17% are in people age 35 and older. More than half of the cases are in people younger than 25.Vaping-related illnesses have been linked to seven deaths, two in California and one each in Kansas, Illinois, Indiana, Minnesota and Oregon.Health officials said the investigation is complex, involving hundreds of patients -- some who are reluctant or too ill to talk with investigators -- and multiple substances."I wish we had more answers," Dr. Anne Schuchat, principal deputy director of the CDC, said during a media briefing.Health officials haven't found a definitive cause or a clear connection between cases. The CDC and various state health departments have reported widespread use of products containing THC, or tetrahydrocannabinol, the psychoactive substance within cannabis. But health officials emphasized Thursday that not all people who became ill had used THC, and many had used multiple substances.Mitch Zeller, director of the US Food and Drug Administration's Center for Tobacco Products, said the agency has activated its law enforcement arm, the Office of Criminal Investigations, to identify what is making people sick and how it's supplied. Zeller said the investigation is ongoing, but the office is not pursuing any prosecutions related to personal use of e-cigarette products.Zeller also FDA has collected more than 150 vaping product samples for analysis in its forensic chemistry center and the number continues to grow. 1916

Travel to Cuba has become more difficult -- and more confusing -- for US citizens and travelers subject to American jurisdiction.Cruise ships will no longer be allowed to sail to the Caribbean island, according to a Trump administration announcement Tuesday, and the industry is scrambling to understand the full implications of the policy change.Norwegian Cruise Line said in a statement that the company is "closely monitoring these recent developments and any resulting impact to cruise travel to Cuba. We will communicate to our guests and travel partners as additional information becomes available."Royal Caribbean Cruise Lines announced that it is changing itineraries for June 5 and June 6 sailings that were scheduled to go to Cuba. The cruise line also said it is still evaluating the impact of the announcement.Several other cruise companies did not immediately reply to CNN's request for comment.Confusion surrounding the ban is palpable among cruise companies, travel websites and passengers with tickets to Cuba.Erica Silverstein, a senior editor at cruise review site Cruise Critic says the company is "in a holding pattern, waiting on next steps as cruise lines work to decipher what today's announcement means for their specific products."As far as ticketed passengers go, Silverstein says they are fielding questions on what the ban means for people who've paid in full or who are waiting to make final payments on planned trips to Cuba."It's worth noting that cruise lines are able to swap itineraries relatively quickly. We see it often during inclement weather, or in the wake of disruption in particular regions," Silverstein explains. "While nothing is definitive right now, if the lines are mandated to cancel sailings to Cuba, we'll likely see changes in the form of itinerary adjustments."The Trump administration policy change also eliminates group people-to-people travel (educational and cultural exchanges of a non-academic nature) as an approved sub-category of travel for Americans.The Treasury Department in a statement clarified that "certain group people-to-people educational travel that previously was authorized will continue to be authorized where the traveler had already completed at least one travel-related transaction (such as purchasing a flight or reserving accommodation) prior to June 5, 2019."JetBlue, United Airlines and Southwest Airlines have released statements saying they are reviewing the changes and intend to comply with the new rules.Under former President Barack Obama, rules around travel to Cuba were loosened, making it easier for individual Americans to comply with certain approved categories of travel without a formal application and approval process.President Trump tightened those rules in November 2017, only allowing people-to-people travel in groups traveling under the supervision of a US entity."That sub-category of travel has been eliminated, but there is a grandfathering provision that basically allows US travelers that have, for example, booked a flight or booked rooms and were contemplating doing a people-to-people trip, they are allowed to complete it," said Pedro Freyre, a partner and chair of the international practice at national law firm Akerman, which has cruise lines and airlines among its clients."But that doesn't align with shutting down the ability of the cruises to go in," Freyre said.It's that misalignment that has cruise lines scrambling to figure out how the new policies will impact their operations.And it leaves passengers booked on upcoming sailings in limbo. 3578
