NBC新闻:女子房间藏炸药被捕

They're the tools of a deadly trade that landed a Florida woman behind bars. Michelle Kolts arrested after her parents discovered an arsenal in the 27-year-old's bedroom and called police. The amount of highly destructive materials we found in this home were astonishing. Inside, dozens of pipes, gunpowder and fuses. Police say Kolts admitted she planned to turn into bombs. 

Alongside DVDs and books about mass murder including the Unabombers and Manifesto. I can tell you we stand here proud knowing that something tremendous was prevented. Kolts's arrest, the latest in what may be a string of thwarted attacks. And August a Florida man was arrested after his girlfriend told police he texted her he wanted to break a world record for the longest confirmed kill ever. We can't say it enough if you see something say something. And tonight officials say it would have taken less than 60 seconds to add the powder to detonate some of those pipe bombs, capable of what authorities are calling catastrophic damage.
