Since October, folks living west of Interstate 17 between Thunderbird and Happy Valley roads have been bombarded by explosions .
The constant barrage of loud booms now has local law enforcement on the clock to figure out whose behind them.
“It’s a terrorist attack, the motive to be determined,” said Steve Hooper.
Hooper spent decades training FBI bomb technicians. We had him take a look at surveillance videos capturing the explosions as well as witness statements.
All in hope of him giving you an idea of the seriousness of what many are now calling a rogue bomber detonating devices around the Valley.
