As the mystery surrounding the disappearance of Jayme Closs intensifies, one thing has become clear. She vanished from her parents' home moments after they were shot to death."We believe Jayme was in the home at the time of the homicides and we believe she's still in danger," Barron County Sheriff Chris Fitzgerald said Wednesday.Three days after a cryptic 911 call led police to discover the bodies of Jayme's parents in their Wisconsin home, the 13-year-old girl remains missing. Investigators have received more than 400 tips and have not confirmed any credible sightings.But the sheriff said he has a "100 percent expectation that she's alive."An Amber Alert was issued Monday for Jayme and several law enforcement agencies have joined the desperate search. 770

Attorney General Jeff Sessions revealed Thursday that Utah's top federal prosecutor, John Huber, has been examining a cluster of Republican-driven accusations against the FBI and has decided that no second special counsel is needed -- at least for now.Huber has been looking into allegations that the FBI abused its powers in surveilling a former Trump campaign adviser, and more should have been done to investigate Hillary Clinton's ties to a Russian nuclear energy agency, but his identity had remained a secret.But Sessions' decision to stop short of formally appointing a special counsel like Robert Mueller, detailed in a lengthy written response to threeRepublican chairmen on Capitol Hill, will likely anger those in the GOP who have recently ramped up calls to investigate claims of political bias at the nation's top law enforcement agencies.It also comes one day after the Justice Department's internal watchdog office confirmed?it would review how the FBI obtained a warrant to monitor Trump foreign policy aide Carter Page, as well as the bureau's relationship with Christopher Steele, the author of the Trump dossier.Huber, who currently serves as the US attorney in Utah, may now find himself thrust into the middle of a fierce partisan struggle -- with Republicans arguing anything short of a special counsel is insufficient because the Justice Department cannot investigate its own people, and Democrats maintaining that any allegations of bias are an unfounded ploy to distract from Mueller's investigation into possible coordination between Trump campaign associates and Russian officials.Originally appointed by President Barack Obama in 2015, Huber, along with many other US attorneys, resigned after President Donald Trump took office early last year, but was reappointed by Trump shortly thereafter. 1845

As states across the country grapple with an increase in coronavirus cases and a huge demand for tests, many businesses are looking for other ways to get more mileage out of their supply chain.Like with anything else, supply and demand is a constant struggle. In this unprecedented era, the demand for things like coronavirus tests is so large that public health departments don't have a choice but to figure out ways to make our supplies last. Several states are examining pooled testing. California's Public Health Department says it's to "better leverage testing resources."Pooling is something that blood banks have used for decades to keep their blood supply safe. Dr. Claudia Cohn is the Chief Medical Officer of the AABB, formerly known as the American Association of Blood Banks.“If you have 100 people that need to be tested and if you test each of them, you’ll do 100 tests. If you find that your test is sensitive enough that you can pool together 20 samples at the same time, instead of having 100 tests, you can have five pools of 20,” Dr. Cohn said.Now, if one of those five pools is positive, then Dr. Cohn says, "You’ll need to break it out and test each of those separately. So, let’s say you have one positive person in a pool of 100 people, you either do 100 tests and find one positive or you do five pools of 20, four of those pools will be negative, so you’ve done 4 pools and covered 80 people."The test works by taking a tiny sample from each person who was tested.“When you take a swab from everyone’s nose, you isolate the DNA from that swab,” Dr. Cohn said about the PCR test, which is generally a nose swab. “It’s not a lot, it’s a small amount but it’s enough. Because these tests are very, very sensitive.”Those tests are so sensitive, and they have to be, that pooling can really only work if the test can handle, as in detect, multiple samples at once. The FDA mandates that.“The FDA is quite demanding as they should be in terms of making sure tests work well and are safe,” Dr. Cohn said.And Dr. Cohn says, pooling wouldn't work in an area where there's a large outbreak, which means a large number of people would test positive regardless of pooling. In the blood world, this strategy has been perfected.“You are taking 100 samples and taking a drop from each sample and putting it together,” Dr. Cohn said. “You are testing every single person who comes through. In the blood world safety is before everything."Blood banks test for HIV, Hepatitis C and B and well as COVID-19 antibodies, according to the American Red Cross. And, as this pandemic moves through our communities, Dr. Cohn says our blood supply needs to remain strong.“After that initial spike, it went down again and that was okay because elective surgery had been canceled, so the demand for blood had gone down as well so for a while we were at a good balance of demand and supply. But then elective surgeries opened up and hospitals went back to full service and we’re in a shortage again,” Dr. Cohn said. 3017
