Now, thanks to new genealogy databases and consumer DNA tests, this tragic case is reaching a close. The boy’s alleged mother, a 57-year-old named Theresa Rose Bentaas, was arrested on the morning of Friday, March 8 and faces charges of first-degree murder, second-degree murder, and first-degree manslaughter.

POLICE FOUND 19 spent shell casings scattered in the San Diego street where Gregory Benton was murdered on April 12, 2014. Benton and his cousin had gone to buy cigarettes, a witness later said. As they returned to a family party, two men pulled up in a car behind them. They got out, and at least one of them opened fire.
Witnesses didn’t get a good look at the men or the car, so when police sat down to review their leads, the shell casings were the best evidence they had. They sent the casings to the San Diego Police Crime Lab, which just happened to be trying out a new DNA testing technique.
Solving a murder or tracking down the perpetrators of sexual abuse often requires dogged police work. What if a machine could help detectives spot the vital clues they need?
A handful of criminal prosecutions have stalled because DNA tests cannot distinguish between suspects who are twins. Then scientists decided to create one.
Now, an interdisciplinary team of researchers has expanded the genetic alphabet by creating synthetic DNA that uses eight letters rather than four, according to a new study published in the journal Science. The new manufactured structure is called “hachimoji DNA,” from the Japanese words for “eight” and letter.”
One researcher, from MIT Lincoln Laboratory, a Department of Defense Federally Funded Research and Development Center (FFRDC), is seeking to simplify and speed up forensic DNA comparisons bit by bit—literally. Darrell Ricke, Ph.D., is leading research at the lab that would reduce the time and computer power needed for DNA analysis, by encoding the millions of loci and alleles into units of computer data that can then be compared using basic logical commands. Two algorithms developed through Ricke’s research to make these comparisons—FastID and TachysSTR—earned Lincoln Lab one of its 10 R&D 100 awards this past November.
When potential DNA evidence—say, from a sexual assault case—is submitted to a forensic lab for analysis, the scientists are often faced with the time-consuming challenge of sorting out which DNA profile came from the victim and which came from the criminal.
BENSALEM, Pa. — They call it the “magic box.” Its trick is speedy, nearly automated processing of DNA.
“It’s groundbreaking to have it in the police department,” said Detective Glenn Vandegrift of the Bensalem Police Department. “If we can do it, any department in the country can do it.”
Thanks to the work carried out by University of Twente Ph.D. candidate Brigitte Bruijns, crime scenes can now be inspected on the spot for the presence of human DNA. In her Ph.D. thesis, she describes a lab-on-a-chip that rapidly indicates whether a trace discovered at a crime scene contains human DNA and, thus, whether it should be examined in the laboratory.
OKLAHOMA CITY — Pending legislation would allow jails to use a relatively new DNA testing method that can deliver results in under two hours, helping law enforcement solve crimes faster.
Comparing an unknown DNA genetic sequence against a known sequence may not create a one-to-one match,” but, “if sufficient human DNA is sequenced at specific marker locations, a DNA profile for the unknown sample could be generated and then used to identify a relationship to known DNA profiles,” including profiles of terrorists, especially terrorists who have been involved in biological and other weapons of mass destruction development or handling; terrorists involved in any sort of bomb-making, or foreign intelligence operatives who’ve left DNA during classified intelligence or covert military operations, according to sources familiar with how the Top Secret program is being used.
Researchers are pushing the boundaries of infrared forensics with promising results for criminal and anti-terrorism investigators
To enhance its multimodal biometric collection for enhanced border security and the prevention of human trafficking and smuggling, the Department of Homeland Security (DHS) is looking for development of “an accredited DHS reach-back capability to review results from fielded rapid DNA systems using the Office of Biometric Identity Management (OBIM) DNA Store/Match/Share (SMS) capability” under a new Small Business Innovation Research (SBIR) Program Solicitation by DHS’s Office of Procurement Operations on behalf of the Science & Technology Directorate (S&T) and the Countering Weapons of Mass Destruction Office.
Forensic samples that have been damaged or purposefully destroyed must be repaired for analysis and use in court. Several methods exist that can repair this damage.
SARASOTA (WWSB) – On September 19th, 2018 came the news that Deborah Dalzell’s family has waited decades to hear.
“Today, more than 19 years after her death, the man responsible is behind bars,” Sarasota County Sheriff Tom Knight announced. “What led to his arrest is unlike anything you’ve heard in the state of Florida. It is something that continues to surface as law enforcement agencies and technology evolve.”
