It will take about a month for Police Commissioner Ray Kelly to decide whether to fire Gescard Isnora, the first cop to shoot at doomed Sean Bell in a 50-shot barrage.

“That process is still ongoing,” Kelly said a day after an administrative judge found Isnora guilty of not following departmental guidelines.

That answer didn’t sit well with Bell’s fiancée, the mother of his two daughters, who made a personal plea to Kelly to give the ax to all five cops who fired shots outside a Queens strip club in 2006.

“Commissioner, please, for our family, for the life and memory of Sean, terminate all these men with no pensions,” Nicole Paultre-Bell said.

“What they did was wrong.”
