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

This year, voters in 31 of the nation’s 100 largest cities will choose a mayor in municipal elections that historically don’t garner the same numbers in terms of voter turnout as presidential elections.But the makers of a new smartphone voting app think they can make it easier for people to vote. This week, Denver became only the second place in the country to ever allow voting by smart phone.It’s called Voatz. Yes, a weird spelling, but it’s a straightforward concept: it’s an app for voting. “To get through verification, they have to take a ten second selfie video,” said Jocelyn Bucaro of Denver’s elections division, who says the app utilizes an individual’s biometric data—like face recogmition or thumbprint technology. “They have to look at the camera, they have to blink, move their head, so that the system knows it’s not a video of a photo," she said. Bucaro thinks that one day, this will be how we’ll all cast our ballots.“If we want to maintain a democratic system and have as many people participating as possible then some form of this will likely be available for all voters," Bucaro said.Right now, it’s just available for active duty military stationed overseas. But there’s a reason for that. Currently service members have to print, sign, scan, then email the document to election officials.Former FBI cybersecurity expert Andre McGregor said that made them the perfect group to pilot the technology.“When you compare it to the current, everything is better than a PDF sent via email, even fax is better than that,” McGregor said.McGregor is talking about the obvious concern with a voting system like this: security, something he says he was concerned about at first, too.“I had just as many skeptical thoughts as most other people thinking about the idea of voting on a device that’s in your hand.”McGregor looked into the potential pitfalls of the app before it went live with West Virginia’s military voters last year, and the app, which uses block chain technology, exceeded his expectations.He says trying it out on small groups is a good way to make sure it’s ready to go mainstream; disabled voters might be next to try it. 2168

There has been talk around the country lately of a recession and what to do to prevent it from happening.President Donald Trump has pushed the idea of significantly lowering interest rates.So, what would that mean for the average American? "What it does is it shifts the economic balance of power towards borrowers and away from lenders,” said Miles Kimball, Professor of Economics at the University of Colorado Boulder. “And guess what, people who borrow money are people who are more eager to spend than lenders." This could make getting a loan easier and more affordable.Kimball says if interest rates drop, it encourages people to spend money they've been saving rather than leave it in the bank."All of a sudden you think about a zero percent loan, obviously the economic benefit is huge there," said a new home buyer, Todd.Zillow says the average price of a home is 1,000. With a 3.8% interest rate, a payment would be ,144, but even if the rate dropped to just 1%, it would be 8. Although that sounds amazing, banks would have to charge fees because they would be handing out more money than depositors are putting in. 1146

Thousands of pro-gun rights activists converged around the Virginia Capitol on Monday to voice opposition to gun control legislation proposed by the Democratic-held legislature.Among the vocal critics of the bills were members of law enforcement, who used their official office to advocate against some of the proposals. The Grayson County Sheriff’s Office posted on its Facebook page its support for the protest. The sheriff’s office also posted photos of deputies in uniform holding a sign saying, “we support the second amendment.”“Great turnout for 2A rally in Richmond today! Standing room only!!” the post read. Culpeper County Sheriff Scott Jenkins also attended the rally to show his support. He said he would deputize gun owners if Virginia lawmakers move forward with gun legislation. It is unclear if said deputies would have arrest power.“My intent was to swear in thousands of auxiliary deputy sheriffs and make it legal for them to possess the weapons that they're trying to ban and restrict,” Jenkins said. Dozens of sheriffs in Virginia have stated that their departments would not enforce gun laws they feel are unconstitutional. Jenkins suggested, but would not directly answer, whether his department would enforce state laws involving gun control if Democrats move forward with legislation.“I'll have to make a determination if these laws they pass or a violation of that,” Jenkins said. Although thousands gathered in Richmond to protest gun legislation, Gov. Ralph Northam said there was a reason why Democrats were elected in Virginia. In his State of the Commonwealth address earlier this week, Northam referenced the legislature’s response to a mass shooting at a Virginia Beach municipal complex last year as a reason why Democrats gained a majority in the Virginia House for the first time in nearly three decades. “Virginians watched. They saw what happened, and they were appalled. So they changed the legislature. And here we are,” Northam said. While a bill to ban assault weapons was dropped earlier last week, other bills are still being considered. One is limiting the purchases of firearms to one a month.Earlier this month, Northam signed legislation to prohibit firearms inside of the Capitol building and an adjacent legislative office building. Another one of the more controversial bills is a so called “red flag” law, which would allow for law enforcement to take away firearms from gun owners who are considered a danger to themselves or others. Northam defended this legislation as “constitutional.” “If you have demonstrated extreme risk of violence, or there’s a protective order against you, you shouldn’t have a firearm. This means universal background checks. If there’s nothing in your record, you have nothing to worry about,” the governor said. Jenkins isn’t convinced. “Right now, it's hard to say that we're going to disarm our citizens who often have a 10- or 15-minute response time in rural areas for an officer to arrive and say we're going to disarm the homeowner and restrict their rights to defend themselves,” the sheriff said.

The Transportation Security Administration plans to send hundreds of officials to help with efforts to deal with migrant inflows on the southern border just as the busy summer travel season begins, according to an internal email obtained by CNN.The task of the TSA workers, which a source said will include air marshals, will be to assist temporarily with immigration duties. TSA acknowledged in an internal email the "immediate need" comes with the acceptance of "some risk" of depleted resources in aviation security.TSA plans for the deployments to involve up to 175 law enforcement officials and as many as "400 people from Security Ops," according to two sources and the email. At least initially, the efforts will not involve uniformed airport screeners, according to the email, which says that some parts of TSA would be asked to contribute "around 10%" of its workforce."There is now immediate need for more help from TSA at the SW border," a senior TSA official, Gary Renfrow, wrote in the email to agency regional management. "TSA has committed to support with 400 people from Security Ops" who will be deployed in waves "similar to support for past hurricanes.""We also understand that we are accepting some risk as we enter a very busy summer," Renfrow wrote, calling this effort an "additional challenge."The initial law enforcement teams will be drawn from six cities, according to a source familiar with the plans.The spokesman for the Department of Homeland Security referred questions to TSA, which did not comment.While airport checkpoint screening may be the most visible part of TSA, Juliette Kayyem, a former DHS official who is a CNN analyst, noted these deployments would draw employees from important behind-the-scenes security work. "That's sweeping airports, that is monitoring activity on the inside and outside of the security line, they're supporting local and state law enforcement," she said.The assignment comes as the number of illegal border crossings is spiking, with apprehensions at a 10-year high. Some 4,300 active duty and National Guard troops are currently assisting on the border, the acting defense secretary said recently, and Customs and Border Protection shifted 750 of its own officers to assignments with Border Patrol last month.
