The murder of Leanne Tiernan It was the evening of November 26, 2000 when Leanne Tiernan, age 16 disappeared on her way home from Christmas shopping with a friend. John Taylor was waiting for a victim to pass through the woods and that victim happened to be Leanne. John grabbed Leanne’s arms from behind her, blind folded her, put his hand around her mouth and led her to his house. It was there that he tied her hands behind her back, strangled her with a scarf and began to sexually assault her. Detective Superintendent Chris Gregg of West Yorkshire Police led the missing persons’ investigation on Leanne Tiernan. The police department knew the investigation was going to be difficult because they were working with an extremely large terrain, …show more content…

After being tested the dye that was on the carpet fibre had also been on Leanne’s body. Forensic scientists were looking to match fibres on Leanne’s clothes with the fibres on Johns carpet but unfortunately that couldn’t be done because John Taylor had set fire to his carpet and there was too much damage to trace a fibre. Although John had burned the carpet forensic investigators found a piece of carpet fibre that was left on a nail from the floor board that matched perfectly with the fibres on Leanne’s Clothes. Not only did the fibre from the nail match up to the fibre on Leanne’s clothes, but after investigators lifted the floor boards there was bloodstains found. After being analysed and tested by forensic chemists the DNA in the blood stains matched Leanne Tiernan. It was pretty clear to investigators who the killer had been after many different evidence was found within John Taylors house but to be 100% sure before convicting anyone there was about 400 items collected and sent for more DNA testing to compare the samples from family, friends and other residents where Leanne had lived. A few items that were collected for example were, magazines, pop cans, papers

    The blood of the unknown person became apparent through comparing the blood type found at the crime scene with the contrasting blood types of the suspects. The blood identified at the crime scene could have possibly belonged to Anna Garcia or Erica Piedmont. This observation was based on the information that the blood type found at the crime scene was type A and these two individuals are the only ones that carry that specific type. In similarity, a microscopic photography was taken of the unknown hair follicle found at the crime scene. Then hair samples were taken from the potential suspects, and the victim. These findings were then compared. This was done by looking at each individuals hair follicles and comparing it with the unknown one. By looking at the similarities and differences in medulla diameter, the discovery of the unknown hair follicle became established that it belonged to Anna Garcia. Further examination resulted in the analyzation of a shoe print found at the crime scene. Shoe patterns and sizes were taken from each suspect, including the victims. They were then identified and compared to the one found at the crime scene. By looking at the distinct pattern, size, and the fact that both shoes were a Columbia brand sneaker it became obvious that the shoe print was extremely similar to Anna’s shoe design.

  • The Case Of The State Of Florida Vs. Chad Heins Case Study

    1611 Words  | 4 Pages

    According to the Innocence Project (2006), “On September 17, 2001, Chad wrote the Innocence Project in New York, which, in 2003, enlisted pro bono counsel from Holland & Knight to file a motion for DNA testing on Tina’s fingernail scrapings.” The state had tested the DNA that was under Tina’s nail from the first case but at that time it was inadequate and could not be tested. It was not until now that we have the technology capable enough to test it. In June 2004, the test came back negative to matching both Jeremey and Chain Heins but did come from an unknown male. The state argued that it was not enough to overturn the conviction so Chad’s attorney asked the state to do some further testing and to compare the DNA from under the fingernails to the hairs that was found on Tina’s body. It was in 2005 that the Florida Department of Law Enforcement confirmed that there was a match between the DNA under Tina’s nail and the pubic hair. According to LaForgia (2006), “this particular type of DNA, the report stated, was found in only about 8 percent of Caucasian American men.” During this process there was a new piece of evidence that Chad’s attorney had learned about during the appeals process, a fingerprint. There were some accusations that the prosecutors never disclosed this information about this third fingerprint and if they did it was too late. The jurors did not even know about this fingerprint and if they did this could have changed the whole case. This fingerprint was found on several objects that included the smoke detector, a piece of glass, and the bathroom sink. It was soon discovered that this fingerprint matched with the DNA found on the bedsheets that Tina was on. This was finally enough evidence to help Chad Heins become exonerated in
