Bite mark analysis

Bite-mark Analysis

    Forensic odontologists, otherwise known as forensic dentists, study the shape of a person’s bite in order to match them with a known sample. Known samples of bites are found on a victim’s body and are seen as an infallible science used to capture the guilty. In reality, bite-mark analysis, or odontology, isn’t as fool-proof as one believes. Several cases have appeared in which DNA testing has proved a convicted person innocent, even after a ‘careful’ examination of the teeth imprints.
    A variety of problems have arose from odontology, the biggest being its claim of infallibility. Odontologists claim that they have 100% accurate matches between the suspects bite-mark and the bite-mark found on a victim’s body. What this statement means is that there is no other person on earth that has the same bite-mark as the suspect, and this is what odontologists truly believe. The problem with this statement is that, like fingerprints, “bite mark methodology has never really undergone sound scientific validation and has never been carefully and critically scrutinised in order to legitimately pass the appropriate tests for admissibility, such as the Frye or Daubert tests as applied in parts of the USA” (Clement et. al.).
    Another problem with bite-mark analysis is the bite-mark itself. Even if no two people on earth had the same bite-mark, or even if it was very unlikely, there is still the issue of the bite-mark itself changing form throughout the healing process. Even if a body is dead. The wound still starts its healing process, not to mention the decomposition process. Other effects on the bite-mark can come from environmental factors such as the bite rubbing up on something sharp and causing other abrasions which might change the bite-marks form. The final problem with the bite-mark itself is that it might not even be a bite-mark (Shelton). It could very well be a bruise they got or an abrasion received from falling on anything rough and sharp like rocks. Overall, bite-mark analysis isn’t as reliable and fool-proof as one would wish and has put multiple innocent people behind bars, on death row, and possibly even led to their death.

Malcolm Bryant: Exonerated by DNA

Malcolm Bryant: Exonerated by DNA On the evening of November 20, 1998, 17-year-old Tyeisha Powell and 16-year-old Toni Bullock were confronted by a man carrying a knife. They were dragged into a vacant lot in Baltimore, Maryland and Bullock was stabbed to death. Powell managed to escape and later gave police a description of her attacker. She only saw him briefly and other factors such as poor visibility in the rain and evening made it hard for her to give an adequate description. A week later with no leads, police receive a phone call from members of the victim’s family saying a man resembling the sketch was just released from jail. Bryant was picked up and immediately put in a photo lineup where Powell identified him as the attacker. Bryant was charged with first-degree murder, even though witnesses placed him at a nightclub at the time of the crime. Bryant was sentenced to life in prison in 1999. Over the years, Bryant filed motions only to be dismissed and until 2009, ...

David Shawn Pope

Voice Comparison Convicts The Crime In July of 1985 in Dallas County, Texas, a man knocked on a woman’s door asking if somebody lived there, and then immediately left. The following morning at 6 AM the woman awoke to find the man standing over her bed with a knife. He assaulted and raped her, and fled the scene. She called the police and reported the crime. In the next following weeks, she was contacted by an anonymous caller who she immediately claimed was the rapist because she recognized his voice. He called several times and the police were able to record a few of the calls. The Investigation The victim was able to help produce a composite sketch of the suspect. David Shawn Pope became a suspect after police saw him around the area and thought he looked similar to the sketch. Pope was presented to the victim multiple times in a photo lineup, along with other similar looking males and no identification was made. After there was no identification, those six peop...
