Dramatic police helicopter footage which has just emerged shows the moment a serial bomber ended his own life as officers surrounded his car.
Mark Anthony Conditt was accused of killing two and injuring four in a spate of random attacks that lasted more than a month in Austin, Texas this March.
The 23-year-old college drop-out sent bombs disguised as packages to his victims and set trip wires made from fishing string, investigators claim.
His reign of terror came to an end after he was tracked down using CCTV footage, phone signals and witness accounts of a customer disguised in a blonde wig and gloves shipping packages.
Having traced him to a hotel in the Austin suburbs, cops tailed Conditt's vehicle and forced it into a road side ditch.
