Several units from the Wheeling Fire Department responded to a structure fire in a residential neighborhood around 7:30 p.m. Friday night on Warwood Terrace. Officials called for city crews to salt the narrow road leading to the hilltop neighborhood in order to navigate fire engines to the scene. Fire had spread to the upper levels of the structure, according to firefighters who first arrived on the scene. No further details were available late Friday night regarding any occupants of the address or the cause of the blaze.
