Bloody Baron searched for her. After Helena was murdered by the Bloody Baron, she became the Ravenclaw house ghost. Tom Riddle, while a student at the school, endeared her ghost so that she would tell him the location of the diadem. Shortly after leaving Hogwarts and after the murder of Hepzibah Smith, he travelled to Albania and retrieved the artifact. Voldemort murdered an Albanian peasant to turn the diadem into a Horcrux.

The event took place just before the opening chapter of Philosopher's Stone. Rowling has explicitly stated that Harry never became a proper "Dark object" since the Horcrux spell was not cast. Regardless, as with all Horcruxes, Voldemort would remain immortal so long as his soul fragment remained within Harry. That portion of Voldemort's soul is unintentionally destroyed by Voldemort himself at the close of the thirty-fourth chapter of Deathly Hallows with the help of the Elder Wand. As a baby, Harry was in the room when Voldemort's fatal Killing Curse backfired. Voldemort's soul had been weakened and destabilised by his continuous murders and the creation of his previous
