Article Synopsis
  • The MaSTR™ software was used to analyze 144 two-person STR DNA mixture profiles, focusing on different degradation levels.
  • A range of mixture ratios (1:1 to 1:10) and DNA amounts (0.1 to 0.5 ngs) were tested, with the software generating likelihood ratio (LR) values for each profile.
  • Results showed that higher-quality (pristine) mixtures yielded strong log(LR) values, while degraded samples often led to lower values or even exclusions, supporting the effectiveness of probabilistic genotyping in forensic science.

Massively parallel sequencing (MPS) of mitochondrial (mt) DNA allows practitioners the ability to fully resolve heteroplasmic sites. In forensic DNA analysis, identifying heteroplasmy (a naturally occurring mixture of two mtDNA profiles) can provide additional mtDNA profile information which can lead to an increase in the discrimination potential of an mtDNA match between an evidentiary sample and reference source. Forensic samples such as hair and skeletal remains, especially older, more compromised samples, can often exhibit DNA damage.

Sister Marija Krucifiksa Kozulić (1852-1922) was a Croatian nun who is in consideration for beatification by the Vatican, which is facilitated by the identification of her 20th-century remains. Sister Marija was buried in a tomb in Rijeka, Croatia, along with other nuns including her biological sister, Tereza Kozulić (1861-1933). When the remains were exhumed in 2011, they were found in a deteriorated state and commingled with several other sets of remains.
