Undoubtedly, the development of technology makes a great contribution to the progress of many sectors. One of these fields, of course, is forensic medicine. Thanks to a new technological development, a murder that has not been solved for many years
The mystery of the case has finally come to light.
In 1989, the murder of a 14-year-old girl was reported in Las Vegas, United States of America. The murder of a girl named Stephanie Isaacson, could not be solved due to time constraint technology and the killer was waving around. However, a new development has managed to shed light on this murder that took place 32 years ago.
Killer detected with only 15 cells
Thanks to the new technology, forensic experts can only see what’s left of that time. Extracting a DNA sample from 15 human cells identified the killer. This development, which surprised everyone, also sold Stephanie’s mother.
Although it is learned that the murderer died in 1995, it is a great achievement to be able to make this determination from a small DNA sample. Police concluded that by genome sequencing and using pedigree data announced that they have reached.
The murder investigation was conducted at Othram, a lab that researches old cases. While DNA sequencing usually requires 750 to 1000 nanograms of DNA samples, in this case only 0.12 nanograms of DNA was present. The detection of the murderer Darren Roy Marchand with these candollar marks the beginning of a new era in the field of forensic science. Marchand’s DNA also matched another murder case that took place in 1986. The company is currently investigating a series of murders that took place from 1881.
