St. Petersburg John Doe (1980) is identified
St. Petersburg Police Department Teams with Othram to Identify a 1980 John Doe
Othram scientists developed a DNA extract from the skull and used Forensic-Grade Genome Sequencing® to build a comprehensive DNA profile. Othram’s in-house forensic genetic genealogy team used the profile to perform genealogical research and generate new investigative leads.
With this information, investigators conducted follow-up inquiries that led them to potential relatives of the unidentified man. KinSNP® Rapid Relationship Testing was then used to compare the comprehensive DNA profile to that of a potential relative. The KinSNP® analysis helped confirm a genetic relationship, leading to the identification of the man as Joseph Richard Murrell, born in 1956.
Murrell died on August 3, 1980, when his car went off the Howard Frankland Bridge. According to news reports at the time, he was decapitated. While all of his remains were initially recovered, it is unclear how or when the skull became separated.''
