Regina's first victim was Rumpelstiltskin's latest "apprentice" in one of the flashbacks from the Season Two episode, (2.05) "The Doctor". When his little con game (with Jefferson and Whale) emotionally broke her, Regina gave in to evil and murdered the apprentice that Rumpel had recruited to take her place. This happened several years before Leopold's death.
