Here's an interesting bit from the Newsweek article. Why this isn't front and center on every nighttime news broadcast is insane:
Ribera was responsible for solving another piece of the RaTG13 puzzle. Had the WIV been actively working on RaTG13 during the seven years since they discovered it? Peter Daszak said no: they had never used the virus because it wasn't similar enough to the original SARS. "We thought it's interesting, but not high-risk," he told Wired. "So we didn't do anything about it and put it in the freezer."
Ribera disproved that account. When a new science paper on genetics is published, the authors must upload the accompanying genetic sequences to an international database. By examining some metadata tags that had been accidentally uploaded by the WIV along with its genetic sequences for RaTG13, Ribera discovered that scientists at the lab had indeed been actively studying the virus in 2017 and 2018—they hadn't stuck it in a freezer and forgotten about it, after all.
In fact, the WIV had been intensely interested in RaTG13 and everything else that had come from the Mojiang mineshaft. From his giant Sudoku puzzle, Ribera determined that they made at least seven different trips to the mine, over many years, collecting thousands of samples. Ribera's guess is that their technology had not been good enough in 2012 and 2013 to find the virus that had killed the miners, so they kept going back as the techniques improved.
He also made a bold prediction. Cross-referencing snippets of information from multiple sources, Ribera guessed, in a Twitter thread dated August 1, 2020, that a cluster of eight SARS-related viruses mentioned briefly in an obscure section of one WIV paper had actually also come from the Mojiang mine. In other words, they hadn't found one relative of SARS-CoV-2 in that mineshaft; they'd found nine. In November 2020, Shi Zhengli confirmed many of DRASTIC's suspicions about the Mojiang cave in an addendum to her original paper on RaTG13 and in a talk in February 2021.
Of course, the only reason Ribera has had to perform such Sherlockian feats is because the WIV has not shared the data investigators have asked for. The WIV maintained a database on its website with all the data on the viruses in its collection, including the many unpublished ones, but that page on its website has been empty for some time. When asked about the missing database in January 2021, Shi Zhengli explained that it had been taken offline during the pandemic because the WIV web server had become the focus of online attacks. But once again, DRASTIC poked holes in this explanation: the database was taken down on September 12, 2019, shortly before the start of the pandemic, and well before the WIV would have become a target.
Other databases yielded other clues. In the WIV's grant applications and awards, The Seeker found detailed descriptions of the Institute's research plans, and they were damning: Projects were underway to test the infectivity of novel SARS-like viruses they'd discovered in human cells and in lab animals, to see how they might mutate as they crossed species, and to genetically recombine pieces of different viruses—all being done at woefully inadequate biosecurity levels. All the elements for a disaster were on hand.
Of course, that is not proof that a disaster took place. Barring unlikely eyewitness testimony, we may never have that. But all the evidence DRASTIC has produced points in the same direction: The Wuhan Institute of Virology had spent years collecting dangerous coronaviruses, some of which it has never revealed to the world. It was actively testing these viruses to determine their ability to infect people, as well as what mutations might be necessary to enhance that ability—likely with the ultimate goal of producing a vaccine that would protect against all of them. And the ongoing effort to cover this up implies that something may have gone wrong. (emphasis added)
