Dаrth Mаul wаs charged with the murder оf Qui-Gоn Jin. Elizabeth was оne of the jurors. During the trial, the court admitted prosecution evidence in the form of a double-ended lightsaber with red blades. Testimony indicated that (1) Qui-Gon was killed by a double ended lightsaber, and (2), such lightsabers were rare and unique, and (3) only Darth Maul used a double-ended lightsaber. Elizabeth wondered about this evidence. That night, Elizabeth wandered the streets of Coruscant and checked out a few shops. She bought two double-ended light sabers that looked just like the one introduced by the prosecutor. The next day she brought them to court, showed them to the jurors in the jury room, and told them where she found the weapons. Maul was acquitted. After the verdict, one of the jurors told the prosecutor what Elizabeth did.
