New funding to help solve Palm Beach County cold cases

The Palm Beach County Sheriff’s Office (PBSO) will receive a $500,000 grant through the Department of Justice’s ‘Prosecuting Cold Cases Using DNA’ program. According to PBSO, the sheriff’s office can now send DNA to private laboratories that use genetic genealogy testing. This testing option is currently not available at the sheriff’s office.

Forensic Genetic Genealogy Laboratory Considerations and Technology Limitations

The application of forensic genetic genealogy (FGG) has technological limitations and will not resolve every case. By taking the time to thoroughly evaluate cases and associated evidence with both local crime laboratory representatives and FGG vendor laboratory representatives, law enforcement investigators can greatly increase the chances of attaining successful case resolutions with FGG. This brief provides the SAKI TTA Team’s guidance on evidence submission based on current successes seen within the field and suggested questions to consider when choosing a FGG laboratory vendor [Description provided by the SAKI TTA website].

People’s Response to Defense Motion to Dismiss for Pre-Indictment Delay (State of Colorado v. Steven Cumberbatch)

Prosecution’s response to the defense’s motion to dismiss the case due to a pre-indictment delay in a Colorado murder-sexual offense case that occurred in 1994. The response addresses the defense’s due process arguments regarding the statute of limitations and the unavailability of witnesses and alternate suspects. The response also noted the advances in forensic techniques that occurred since the date of the incident which enabled investigators to utilize the Combined DNA Index System (CODIS).

People’s Motion in Limine (State of Colorado v. Steven Cumberbatch)

Prosecution’s motion in limine in the trial of a Colorado murder-sexual offense that occurred in 1994. The prosecution sought to admit “sanitized” police encounters with the defendant that occurred in Denver during the timeframe prior to the murder to limit any unfairly prejudicial details or facts.

Human Forensic DNA Analysis Process Map

The Human Forensic DNA Analysis Process Map is intended to be used to help improve efficiencies while reducing errors, highlight gaps where further research or standardization would be beneficial, and assist with training new examiners. It may also be used to develop specific laboratory policies and identify best practices [Description provided by the NIST Human Forensic DNA Analysis Process Map].

Exoneration of Terance Calhoun

In 2007, Terance Calhoun was convicted of sexual assault of two victims. DNA testing excluded him in 2007. Additional DNA testing was performed in 2019 by Bode confirming the original testing. On January 10, 2022, the Michigan State Police reported that a search of the FBI DNA database linked the DNA profile from the condom to a man who “is currently charged with other sexual assault offenses in the Detroit area that are alleged to have occurred between 2007 and 2014.” He was exonerated in April 2022.

National Best Practices for Improving DNA Laboratory Process Efficiency

DNA forensic laboratories are at a crossroads. Faced with a rising demand for analysis and constrained by limited financial resources, laboratories must find new and innovative ways to reduce backlogs and increase productivity. The recommendations in this National Institute of Justice-produced guide, authored by experts in forensic science and laboratory management, are aimed at improving efficiency in a multitude of essential tasks that DNA forensic laboratories routinely perform. These tasks range from hiring and training personnel to formulating and enforcing case acceptance policies, implementing existing and new technologies and methodologies, managing casework and tracking laboratory workflows, analyzing data, and compiling final reports that nonscientists can comprehend. This guide’s recommendations are also designed to help laboratories anticipate changes — including technological advances and new legislation — that may affect their caseloads [Description provided by the NIJ website].

Maricopa County receives $3 million in federal funding to help solve crimes

The Maricopa County Attorney’s Office (MCAO) announced that it would receive about $3 million in grants from the Department of Justice to help victims of crime. MCAO’s $500,000 Prosecuting Cold Cases Using DNA (COLD) Program grant will enable additional DNA testing, the creation of a countywide database of cold cases, hiring of a data analyst, and an increase of resources available for prosecutors who specialize in cold case homicide investigations. This is the first time MCAO has been awarded this grant, and their goal is to increase the number of successful prosecutions of cold cases throughout Maricopa County and provide closure to the victims of violent crimes.

Denver Police solve four related cold case homicides that occurred between 1978 and 1981

The Denver Police Department and law enforcement partners today announced that through the continued determination of investigators, DNA evidence, investigative genetic genealogy and familial DNA search, the suspect in three Denver cold case homicides and an Adams County cold case homicide has been identified as Joe Michael Ervin (DOB: 6/25/51), who is deceased. The murders of three women and a teenage girl occurred in separate incidents between 1978 and 1981. The four cases were linked together and solved through several significant investigative developments beginning 35 years later. The final identification of the suspect in these four murders through Investigative Genetic Genealogy and familial DNA research was a result of Denver’s Integrated Cold Case Project. This project is funded in part through a 2020 Genetic Genealogy & Familial Match Searching grant, awarded to the Denver Police Department by the Bureau of Justice Assistance for a total of $470,000.
