Shiranui arrived with the twins.  He saw Liam at work putting the fire out and addressed Officer Jenny.  "Jenny, have your Growlithe use Odor Sleuth," he suggested, "The pyromaniac behind this arson attack would not think to disguise their scent and would likely have a Fire-type Pokémon on hand.  Hoshi, use Hydro Pump and help extinguish this fire!"  Shiranui sent his Starmie out and Hoshi snapped into action.  The Starmie leaped into the air and sprayed powerful blasts of water from all ten of its limbs while spinning at a high speed, making like a powerful water sprinkler and ensuring all the hotspots in the immediate vicinity were extinguished.
