A murder case on America’s Most Wanted list was being investigated by a forensic scientist, Dr. John Bond, from the university of Leicester and Northamptonshire police. Dr. Bond developed a new technique that enables scientists to see fingerprints on metal even after the print has been removed. Dr. Bond worked with US Police before to find prints on bullets fired about decade ago. He worked with casings from the Marianne Wilkinson murder case –currently cited on the America’s Most Wanted website. Dr. Bond stated that “I am confident that if any fingerprint deposit has corroded the metal shell casing then our new technique will find it.”
Around 7:30 PM on December 9, 2007, somebody rang Marianne Wilkinson’s bell in North Richland Hill, Texas. Marianne was greeted by four gunshots. She died on her front porch after the police arrival. A neighbor who was going through a complicated divorce believed that she was the target. She lived one street away with the same number in the same housing community. According to Wilkinson’ family and friend, the 68 year old had no enemies and nobody would have wanted to kill her. Later, a handgun was discovered and confirmed to be the one used to kill Marianne.

CSI insects
The Forensic Science Service (FSS) requests assistance from insect’s experts at the Natural History Museum to help solve murders cases. The insects present on the victims’ body can help determine the time of death. Forensic Science Services turn to several experts, including entomologists from Natural History Museum in London to review criminal evidence.
Forensic entomology played significant role in big cases, and insect evidence has been admitted in court in the past, but had little regulation. “Under some circumstances, such as when a body has been burnt, or if it is badly decomposed, it can be difficult to ascertain a time of death using traditional pathology techniques”, (Devlin, 2009). Entomologists can determine the age of the insects and the generation of insects found on the body. Therefore, this enable scientist to calculate the minimum amount of time that the body has been at the site. Insects can also help finding the cause of death. The body might be too decomposed to get a blood sample. However, traces of a drug might be detected from the blood of the insects living on the body (Devlin, 2009).
I believe that this technique has great potential in forensic science. I suspect that there would be more interest in it in the future. The number of missing children and women seems to be escalating every day. Victim’s bodies are found after months and sometimes years after the crimes. It would be interesting to see how forensic nursing might get involved in this field in the future.
