Monster enhancer and Dead

I am fighting a monster that provides 2 treasures if killed. Then someone plays an enhancer that gives a +5 to the monster and an extra treasure if the monster is defeated. I can't beat it, so I play the Monster-is-Dead card that says to get the treasures from the monster but not the level. Do I get the extra treasure from the enhancer too? Did that counted as defeat, since the monster was already Dead?

Would the same apply if I was a Wizard and charmed the enhanced monster?
