This is next to impossible to answer. First, some of the original fish may have been carrying something. Or the stress may have overwhelmed them. Ich only occurs due to stress, always. Ich is now known to be present everywhere, but the fish only succumb when stressed sufficiently to be unable to fight it off. So clearly something caused the initial stress, and this could have been some protozoan, weak fish that couldn't withstand the netting/transport, shock from water parameter differences, internal damage along the way from hatchery to your tank,... who knows.
The aggressive behaviour of that one fish is almost certainly to have been caused by stress from, again, something. Obviously, this fish aggression added more stress to the others.
The salt likely contributed after the initial issue. A stressed/weakened fish is going to be more unlikely to deal with additional stress, so this just compounds. I know many still advocate using salt; I obviously do not. One has to recognize the possible side effects of any treatment, and for me salt has way too many especially for soft water fish.
