Fire Marshal Jason McIntosh provided this story:

On the evening of 11/17/18, crews responded for the report of an apartment fire.  Upon arrival, fire crews entered the apartment and found that the fire had been extinguished prior to arrival by one sidewall sprinkler located in the kitchen of the apartment.  While overhaul and ventilation were required, no further extinguishment was needed.  The fire has been attributed to unattended cooking.
