Casey Anthony Trial Update: No Valid Method to Prove Human Decomposition, Claims Expert

Monday morning, after Casey Anthony's adequate competency to proceed in trial was confirmed, the first-degree murder trial has resumed in the midst of national attention, or rather addiction, to the unfolding mystery of 2-year-old Caylee Anthony's death.

The first witness to testify on June 27 was lead detective Yuri Melich.

The defense questioned him about the reason he did not request phone transcripts for Roy Kronk through December 2008. The toddler's reamins were first found by Kronk in December 11, 2008. The defense claimed that Kronk had a possible history of inappropriate behavior with young girls, and a history of abusing, restraining, and holding women against their will.

Melich testified that he requested Kronk's records from June and July. While he previously testified that he requested the records through December 2008, Melich on Monday admitted that he made an error, unintentionally.

Lead defense attorny Jose Baez listed out all the people involved in the case for whom Melich had cell phone records subpoenaed. Baez also noted that Kronk's computer records were not searched, either.

Orange County Sheriff's Office crime scene investigator Michael Vincent was then called to briefly review a previous drawing of the Sheriff's Office's forensics bay where Anthony's white Pontiac Sunfire was examined, according to WKMG.

Next, OCSO crime scene investigator Gerardo Bloise testified that his investigation was focused only on Anthony's car.

Baez then called K-9 handler Deputy Jason Forgey, whose dog Geris alerted to the smell of a human body in the car trunk as well as the family's backyard.

Baez asked Forgey several questions about bias and the possibility of a handler encouraging a dog to alert in a particular location.

The next testimony came from Dr. Kenneth Furton, a professor in the chemistry department at Florida International University studying chemistry of human decomposition and the scent of human remains.

It's my expert opinion that there's currently no instrumental method that has been scientifically validated to the level that it could be used to identify the presence or absence of human decomposition, Furton said.

According to Furton, many of the compounds found in the trash of Anthony's trunk are the same as what Dr. Arpad Vass relies on in his findings of acetic acid in the air sample from the car trunk and subsequent claims that it is a byproduct of human decomposition and manufacturing chloroform.

Casey Anthony is accused of murdering Caylee Anthony, her daughter, by applying chloroform first, sealing her mouth with duct tape, and dumping the body in the woods near her parents' home.

2-year-old Caylee's body was found in November 2008.

Casey Anthony denies the charges that she murdered Caylee. She contends that Caylee drowned accidentally in the swimming pool.

The trial, which began on May 24, 2011, has become more intricate due to the lack of evidence. A string of expert witnesses took the witness stand on June 22, but none of their testimonies could prove that Casey had killed her 2-year-old daughter Caylee. Meanwhile, Casey's mother Cindy testified that she, not her daughter, made online searches for chloroform, which shook the courtroom. Lee Anthony, Casey's brother, also gave a surprising testimony saying that his family had denied and hid Casey's pregnancy in 2005 until the baby was about to be born.

The credibility of the family members' testimonies is widely questioned.

The validity of the scientific investigations have also been challenged in court.

The trial is nearing its end and it is believed the jury deliberation will begin soon.
