You get the token, not the player who controlled the creature.

The power and toughness of the token are based on the destroyed creature’s last existence on the battlefield. The token doesn’t have any of the destroyed creature’s other characteristics.

If the targeted creature has indestructible or regenerates, you won’t get a Vampire token. Similarly, if the targeted creature is destroyed but a replacement effect moves it to a different zone instead of its owner’s graveyard, you won’t get a Vampire token.
