On Tuesday, a photo that is believed to have been accidentally taken of Travis Alexander's wounded body was shown to the jury in the Jodi Arias murder trial. The photo might have been taken at the time of Alexander's death.

Alexander appears to be lying on his stomach, and his head and bloody arm are visible.

Watch video to see In Session correspondent Beth Karas explain the graphic photo.

Arias is on trial for killing Alexander her ex-boyfriend. Alexander died in a brutal attack. He was stabbed in the heart, had two dozen knife wounds, his throat was slit and he was shot in the head.

Arias originally told police she was not involved in his death. She later changed her story and told investigators that two intruders broke in and killed him. She eventually admitted to killing Alexander in self-defense.
