When DNA analysis was first discovered, a process called Restriction Fragment Length Polymorphism (RFLP) was used to analyze DNA. However, RFLP was an inefficient process due to the fact that it used up large amounts of DNA which could not always be obtained from a crime scene. Modern day technology has evolved beyond RFLP.
Investigative genetic genealogy, also known as forensic genetic genealogy, is the emerging practice of utilizing genetic information from direct-to-consumer companies for identifying suspects or victims in criminal cases. [1] As of December 2023, the use of this technology has solved a total of 651 criminal cases, including 318 individual ...
The use of DNA sequencing has also led to the development of new forensic techniques, such as DNA phenotyping, which allows investigators to predict an individual's physical characteristics based on their genetic data. In addition to its applications in forensic science, DNA sequencing has also been used in medical research and diagnosis.
A pair of men already serving life behind bars have been charged in two Tampa Bay-area cold case murders thanks to DNA evidence that previously helped exonerate a death row inmate.
The death row inmate, Ruben Gutierrez, appealed a lower court's ruling against his challenge to a Texas law limiting the use of DNA testing after a person has been convicted of a crime.
A Missouri inmate convicted of fatally stabbing a woman in 1998 will avoid the death penalty and instead be sentenced to life in prison without the possibility of parole, prosecutors said on ...
The researchers used data from 17 actual cases to test their model. In each case, the target’s DNA—that of the suspect or the victim—produced anywhere from 200 to 5,000 matches.
Touch DNA was introduced in the third trial of David Camm by the defense. The DNA profile of another man, Charles Boney, was found on a number of objects at the crime scene, including the panties of Camm's wife Kim and a fingernail that is thought to have broken off during the struggle. The DNA evidence aided in his acquittal of the murders. [11]
