The Austin serial bomber suspected of delivering six homemade bombs to locations around Austin this month, killing two people, has died after blowing himself up. Less than an hour after CBS Austin released photographs of the suspect at a Fed-X facility, media reported of an officer-involved shooting on I-35 in Round Rock. Police have identified the dead suspected bomber as a 24-year-old white male, according to the Associated Press.

According to https://twitter.com/KVUE!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+"://platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");, the FBI and police tracked the bomber to the Round Rock area using cell phone technology, security video, store receipts before 'engaging him' around 3am on Wednesday. Then, as officers pursued the suspect a device was detonated, before a volley of gunfire. The shooting came just hours after CBS published CCTV showing images from a surveillance video from the FedEx Office store on Brodie Lane in South Austin which helped investigators zero in on the suspect. According to the Daily Mail, the images show a man - possibly wearing a wig and gloves - delivering two packages around 7.30pm on Sunday. One of the packages subsequently exploded on a conveyor belt at a FedEx sorting facility outside of San Antonio in Schertz. The other was intercepted at a facility near Austin airport and was later confirmed to contain a bomb.
