Michael Gargiulo is facing two counts of murder and one of attempted murder from attacks between 2001 and 2008
These are the grisly crime scenes left behind by the alleged Hollywood Ripper serial killer which have been shown to a jury, along with a diagram showing the stab wounds suffered by Ashton Kutcher's ex girlfriend during the frenzied attack which left her dead.
Michael Gargiulo, 43, is accused of murdering two women, the actor's former partner Ashley Ellerin, 22, and Maria Bruno, 32, as well as trying to kill another, Michelle Murphy, in the Los Angeles area between 2001 and 2008.
He was separately charged with killing an 18-year-old Illinois woman, Tricia Pacaccio, whose father found her fatally stabbed on their family's doorstep with her house key still in hand in 1993.
Disturbing images from inside the home of one brave survivor, Michelle Murphy, show her bloody bedding and the blood splattered walls and floors of her apartment as she fought off her attacker and survived.
The defendant, dubbed 'the boy next door killer', is said to have stabbed Michelle multiple times at her Santa Monica home before she bravely fought him off and survived the attack in 2008.
A diagram shown to the jury indicated just how close Michelle lived to Gargiulo, an air conditioning repairman, who would allegedly 'watch, shadow, stalk and hunt down' his victims who lived nearby before fatally stabbing them for sexual pleasure.
Images seen by the jury show the window to Michelle's apartment with a sliced open screen and pictures from inside her bathroom show the aftermath of her attack as she tried to stem her heavy bleeding.
Even more sickening is the hand prints left on her hallway floor as she fell trying after being stabbed and images of the defensive wounds on her hands from fighting off her attacker, which has left her scarred for life.
Prosecutor Daniel Akemon told the jury Thursday that Gargiulo - a neighbor of each victim at the time of the attacks - could watch Michelle, who said she woke to find him in her home one night. They also argued his DNA was on her comforter.

Another of Gargiulo's alleged victims, Kutcher's ex Ellerin, was found dead in 2001 in her Hollywood Hills home. The actor told police he went to pick up the fashion student-model for a post-Grammy Awards party, but she did not answer the door.
He checked a back window and spotted what he thought were red wine stains on the carpet and then left. Her body was discovered the next day by a friend.
The prosecutor showed diagrams of the stab wounds next to the actual photos of Ellerin's body to the jury as the trial got underway Thursday.
Ashley was stabbed to death in the hallway outside her bathroom,' Akemon told the jury. 'She was stabbed over 47 times…she was almost decapitated.'
Ellerin was left with gaping wounds - some up to six inches deep -by a knife-wielding intruder who attacked her while she was taking a shower.
Akemon also showed horrifying images from inside the home of 32-year-old Maria Bruno, found stabbed to death in suburban El Monte in 2005.
