Since when is a kitchen high tech? I’m willing to bet they have a mini fridge, water cooler/fountain, and dozens of other electric devices in said building that could have been the cause. But no, go ahead blame arson while it is still smoldering.
It’s not like somebody could have left a coffee maker or hot plate turned on or something. /s
