Heather Conner, a latent fingerprint examiner for the Mesa Police Department, took the stand Tuesday in the Jodi Arias trial and walked jurors throughout the bloody scene inside Travis Alexander's house.
Watch the video to see the highlights of Conner's testimony.
Soon after Alexander’s body was found in June 2008, Arias told police she was not involved in Alexander's death. She later changed her story and told investigators that she witnessed two intruders break in and kill him. She eventually admitted to killing Alexander, saying it was in self-defense.
