You are missing the bigger picture. Why Omega Ekko if you are controlling him? We can use that to deduce that the one who controlled Ekko and the one who killed him are from different factions. Moreover, they were either afraid of being targeted or are small enough that Red Mafia hurting them might set them back.
I suspect we are dealing with two scum teams of about 3 to 4 in size, and probably 3 Indies. One anti town, one neutral, one pro town.
