Photographs presented at the murder trial of an Arizona woman charged with killing her former boyfriend show a chilling portrait of sex and death.

There’s a nude Jodi Arias on Travis Alexander’s bed, a naked Alexander in the shower and an image of Alexander stabbed and shot in the head — his throat slit.

Other evidence also has stacked up since the June 2008 attack in the Phoenix suburb of Mesa: a bloody palm print, conflicting stories and, finally, a confession.

That evidence is being presented this week at a trial dominated by stories of sex and jealousy.

Arias admits she killed Alexander, but claims it was self-defense. Prosecutors say she planned the attack.

She could become the fourth woman on Arizona’s death row if convicted.
