When Gordon says that Two-Face killed five people including cops, who were all the people? (please help my sister and i have been trying to figure this out for ages)

I can't really answer this سوال but I have a theory. I think the five people he reffers to are Maroney and his driver, Det. Wuertz (at the bar), the bar tender, and finale, Dent himself. If i recall correctly gordon say "5 people dead, 2 of them cops" so I think this sort of makes sence.

But, didn't he kill Officer Martinez too?
