Скачать или смотреть True Crime Forensic Fails: When Criminals Tried to Clean Up

Here are three compelling true crime stories where perpetrators attempted to clean up blood and other forensic evidence to evade detection:
1. The Murder of Travis Alexander by Jodi Arias

Background: In 2008, Travis Alexander, a motivational speaker and salesman, was found dead in his home in Mesa, Arizona. He had been brutally murdered, suffering from multiple stab wounds, a slit throat, and a gunshot to the head.

Crime: Travis’s ex-girlfriend, Jodi Arias, committed the murder. She had driven from California to Arizona to confront him about their relationship.

Cleaning Up Evidence: After killing Travis, Jodi Arias attempted to clean up the crime scene. She washed Travis’s body and bedding, tried to erase bloodstains, and deleted photographs from a digital camera that captured images of her and Travis during the attack.

Outcome: Despite her efforts, forensic investigators found significant evidence linking her to the crime. Blood traces, palm prints, and the recovered photographs on the camera provided overwhelming proof of her guilt. Arias was convicted of first-degree murder in 2013 and sentenced to life in prison without parole.
2. The Murder of Meredith Kercher

Background: In 2007, British exchange student Meredith Kercher was found dead in the apartment she shared with Amanda Knox and others in Perugia, Italy. She had been sexually assaulted and stabbed to death.

Crime: The investigation initially focused on Amanda Knox, her boyfriend Raffaele Sollecito, and Rudy Guede. Guede was convicted based on DNA evidence, but Knox and Sollecito's involvement was heavily debated.

Cleaning Up Evidence: The crime scene had been partially cleaned. Investigators found signs that someone had attempted to wipe away bloodstains and clean up the area. However, they still found significant forensic evidence, including mixed DNA samples from both Kercher and Knox on a knife and in other areas of the apartment.

Outcome: Knox and Sollecito were initially convicted, but their convictions were later overturned due to insufficient evidence and concerns about the forensic procedures used during the investigation. They were finally acquitted in 2015, while Guede served his sentence.
3. The Murder of Helle Crafts

Background: In 1986, Helle Crafts, a Danish flight attendant, disappeared from her home in Newtown, Connecticut. Her husband, Richard Crafts, claimed she had gone on a trip but her friends and family suspected foul play.

Crime: Richard Crafts killed Helle and dismembered her body using a chainsaw. He then attempted to dispose of her remains by running them through a wood chipper, scattering the fragments into a lake.

Cleaning Up Evidence: Richard meticulously cleaned up the blood and other forensic evidence from his home and the vehicle he used to transport Helle’s body. He believed the wood chipper would effectively destroy all evidence of the crime.

Outcome: Despite his efforts, investigators found small pieces of bone, tissue, and personal items belonging to Helle near the lake. These fragments, along with forensic analysis and witness testimonies, led to Richard Crafts’ conviction. He was sentenced to 50 years in prison, and the case became known as one of the first in the U.S. to secure a murder conviction without a body.

These cases highlight how cleaning up blood and forensic evidence can delay an investigation but often cannot prevent skilled forensic teams from uncovering the truth.
