The bombs were packaged in manila envelopes with bubble-wrap lining, according to the FBI. They each bore computer-printed address labels and six American flag stamps. Some went through the US mail service while others appeared to be delivered by individuals.Investigators will be looking for fingerprints on the package, on the back of any tape that may have been used, and on the stamps and labels. If the seals were licked, investigators may be able to pull DNA from the saliva, officials say. They will also look for any hairs or other materials that could help identify the sender or location.Other information on the packages will also be rich investigative lines. If the packages were scanned by the US postal system, investigators may be able to determine which machines scanned the documents and when. However, unlike FedEx or other private mail delivery services, the US mail system is not set up to track every single piece of mail.Authorities believe several of the packages went through the Opa-locka, Florida processing and distribution center. According to a US Postal Service employee, this facility handles mail that is incoming and outgoing from south Florida.Investigators who traced a string of package bombs in Texas that killed two people and wounded five in March used those same tools to pull DNA from the packages.In addition, investigators used signals from cell phone towers to help narrow down the potential suspects in the area at the time the packages were dropped off, according to a law enforcement official. They relied on closed circuit cameras to narrow the field further, the official said. It took investigators 18 days to track down Mark Anthony Conditt, who killed himself with one of his own explosive devices.Those tactics are likely to be deployed as authorities trace couriers and any individual who may hand delivered the packages. Authorities believe the package sent to George Soros, the billionaire philanthropist who has backed Democrats, was hand delivered to his residence in Westchester County.All of the bombs are being transported to the FBI lab in Quantico, Virginia, for analysis, officials say.At the lab the bombs themselves will be dissected. According to a law enforcement official, the bombs so far appear to show the presence of a sulfur substance, which would be the ingredient that was intended to explode. Authorities will examine the components of the bomb and look for clues as to where they may have been purchased and any similarities or differences between the individual packages. Pipe bombs are inherently unstable devices and could be set off simply by handling them.Outside experts have pointed to the lack of a triggering mechanism, suggesting it was never meant to explode. The device includes very common components, making it more difficult to get clues from the signature of the bomb. But the components could still provide clues -- like the clock and the tape used.New York City Police Commissioner James O'Neill told CNN Wednesday that investigators are reviewing security video to try to identify the courier who delivered the package to CNN's New York office. O'Neill said he was "pretty sure those images will be caught on video and we'll be able to find out where that person came from before they entered the building and where they went to after." 3333

The cremations weren't uniform, either, utilizing different fuel or occurring under different conditions. For instance, the locals were cremated likely using a pyre built with wood that was grown in an open setting, like the landscape around Stonehenge. The others were cremated with wood that came from dense woodlands, exactly like the landscape in west Wales.But if these people were cremated in Wales, how did they end up at Stonehenge?During his 1920s excavations, Hawley noted that some of the cremated remains in the Aubrey Holes were stored in leather bags, which led him to believe that they "had apparently been brought from a distant place for interment."Perhaps their remains were brought from Wales and buried when the bluestones were being raised at Stonehenge, the study authors suggest. This knowledge is compelling to the researchers, given that a recent theory suggests the bluestones initially stood within the Aubrey Holes themselves.Being able to connect the stones and human remains to Wales provides more intriguing theories and rare insight for researchers as well.This suggests that the construction of Stonehenge required connections that were 140 miles apart. As early as 5,000 years ago, Neolithic people and materials were going back and forth between west Wales and Wessex to build and use Stonehenge.Snoeck hopes to develop new methods and apply his technique at other sites containing cremated remains. But the gravity of working with human remains from Stonehenge was a privilege."It was extremely exciting and terrifying at the same time," Snoeck said. "In a way, it was like giving them a new life." 1634

The city switched its public water source from Lake Huron to the Flint River in an effort to reduce costs during a financial crisis, but corrosive water caused lead to leach from pipes, 186
