Another explosion injures 2 in Austin, Texas; cause unclear - EarthLink - U.S. News

Late last week spokesman said that the 2 incidents were unrelated. We knew that wasn't true based on how the devices functioned. This third package should serve as a warning to the Austin community to be extremely careful around unattended packages. If you aren't expecting something, it probably isn't something to mess with. Anyone with friends or family in the area needs to be on the look-out for anything suspicious.
Just my 2 cents.
