Austin authorities say the use of “exotic” batteries helped them track down the Austin bombing suspect, which resulted in his death early Wednesday morning. After working to track and find the suspect responsible for the various bombings around Austin, Texas, authorities are confident in identifying the man as 24-year-old Mark Anthony Conditt. Officials say Conditt used “exotic” batteries that one could not find in a regular convenience store or even an electronic store. Most likely these unusual batteries originated in Asia and had to be ordered online; however they became the signature property that allowed investigators to quickly connect the various explosions to the same suspect after they took surveillance footage from a FedEx store which showed Conditt dropping off packages containing the explosives. Conditt died in his vehicle after detonating a bomb on the side of Interstate 35, after SWAT forces began encircling him to bring him into custody.
