Law enforcement agencies across Texas are training on how to turn the chaos of an explosion scene into critical evidence that can help track down suspects. During a recent training in San Antonio, bomb technicians and investigators focused on post-blast response, learning to identify even the smallest details like wiring fragments, power sources, and triggering mechanisms that can provide clues about the type of device used and point them in the right direction.

Why it matters

Understanding the aftermath of an explosion is just as important as prevention efforts, according to officials. Investigators have cited past cases like the Austin serial bombings, where evidence recovered from blast scenes played a key role in identifying how devices were built and advancing the investigation.

The details

During the training, controlled explosions demonstrated how even small amounts of explosives can cause significant damage. But beyond the destruction, each blast leaves behind a trail of evidence that investigators are trained to meticulously document and analyze. They look for fragments of wiring, power sources, and triggering mechanisms that can reveal details about the device, such as whether it was triggered by a garage door opener or a battery.

  • The training was held on Monday in San Antonio's south side.
