New advances in genetic testing allowed police to have the genetic samples collected at crime scenes compared with people who submitted their DNA to explore their family lineage. That led police to five relatives, and detectives narrowed the list to a suspect who had lived in Maryland at the time of the attacks and worked as a landscaper.

Mr. Trump did not provide any details of how that identification was made. But the quick turnaround after Mr. al-Baghdadi’s violent demise suggests that American Special Operations forces made use of biometric tests and DNA technology, which has advanced significantly in recent years.
A group of archaeologists and researchers announced Tuesday that they recreated the face of a medieval man whose remains were dug up in a Scotland museum four years ago.
The man, who researchers identified as Skeleton 125, was found among 60 skeletons and 4,272 bone fragments on the site of the Aberdeen Art Gallery in Aberdeen, Scotland amid construction of a new development on the site.
But authorities used DNA evidence and forensic genealogy to identify her killer as Phillip Cross, who was 21 at the time. Cross died of a drug overdose in 2012.
Authorities linked the suspect through a DNA match of the suspect’s second cousin.
Bjerke was one of the first offenders identified in Virginia using forensic genealogy, an increasingly common technique for solving cold cases where police have little evidence beyond DNA. Bjerke had no criminal history, and so his DNA was in no law enforcement database. But sperm left at the crime scene matched with relatives of Bjerke who had uploaded their genetic information to public genealogy databases.
Voiceprint technology works by first securing an initial recording of a known individual. For example, a prison may ask an incarcerated individual to provide a sample voice recording; a bank may record a client once the client goes through an alternate verification process. The technology then analyzes hundreds of components of that user’s voice and creates a voiceprint, which is stored in a database and associated with that individual. When subsequent calls are made, the technology creates a new voiceprint and compares that to the known voiceprint to confirm the caller’s identity. This matching process parallels that of other biometric verification processes such as DNA and fingerprint matching.
Those fortunate enough to have a head of hair generally leave 50 to 100 strands behind on any given day. Those hairs are hardy, capable of withstanding years or even centuries of rain, heat and wind.
The trouble for detectives, or anyone else seeking to figure out whom a strand of hair belonged to, is that unless it contains a root, which only a tiny percentage do, it’s about as helpful as a nearby rock.
Now researchers like Dr. Mounier are using computers and mathematical techniques to reconstruct the appearance of fossils they have yet to find. On Tuesday, Dr. Mounier and Marta Mirazón Lahr, a paleoanthropologist at the University of Cambridge in Britain, unveiled a virtual skull belonging to the last common ancestor of all modern humans, who lived in Africa about 300,000 years ago.
DNA evidence has revolutionized forensic science in the past few years, cracking open cold cases and bringing both convictions and exonerations. The same techniques help archaeologists and anthropologists studying remains from ancient peoples or human ancestors.
But DNA is a relatively fragile molecule that breaks down easily. That’s where proteomics, the new science of analyzing proteins, comes in. By reading the sequence of amino acids from fragments of protein, scientists can work backwards to infer the sequence of DNA that produced the protein.
New chip device enables the detection of much smaller blood samples at a crime or accident scene.
Developed at MIT Lincoln Laboratory, IdPrism and its award-winning algorithms provide rapid analysis for complex forensic DNA samples.
A new forensic technique could help identify perpetrators of sexual assault using a kind of evidence typically deemed unreliable by the scientific community: hair.
Word of the arrest — via a friend’s text message — hit Wayne Sankey like a thunderbolt.
“I said, ‘You gotta be kidding me,'” Sankey recalled. “And then I told the wife and she couldn’t believe it. ‘There’s no way,’ she said. ‘Ray down the road?'”
Almost 37 years later, with the help of DNA detectives, genealogy records and dogged detective work, the mystery was solved. The victim in the lonely grave is Mary Silvani, a Pontiac, Michigan, native who grew up in Detroit, had two brothers and eventually moved to California.
Might the solving of a 46-year-old homicide in Vigo County lead police to the answer of who killed an Indiana University student 42 years ago?
