In recent years, Canadian police have looked to genetic genealogy to help solve cold cases dating back decades. The technique is relatively new and is continuing to make headlines — including this past week, when it was revealed that the murder of a Montreal teenager had finally been solved. Sharron Prior had never been forgotten in the decades that followed her death. Police questioned scores of people, but an arrest was never made. Almost five decades later police say her killer has been identified through investigative efforts that included genetic genealogy — a technique whereby genetic database information is used to look at potential family lineages, in this case in a criminal investigation context. Here's a brief look at other cold cases where the same investigative technique has been used. In February, police in Windsor, Ont.

Many breaks in these cases came just in the last year. These discoveries have brought justice and closure for hundreds of victims and families of victims who've spent decades without answers. But the use of investigative genetic genealogy is not without controversy, and as more law enforcement agencies utilize the technology, privacy implications of the technique have come under scrutiny. In , investigators and genetic genealogist Barbara Rae-Venter used a new forensic technique known as genetic genealogy to connect Terry Rasmussen, also known as the Chameleon Killer, to the Bear Brook murders. They also discovered he was the father of the middle child. At this time, Rasmussen was seven years dead, and the identities of the four girls still remained a mystery. Heath was looking for clues on ancestry websites to help identify the victims when she discovered the Honeychurch family searching for their daughter, which matched the timeline of the murders. Rae-Venter used genetic genealogy to confirm their identities. The identity of the the fourth victim, Rasmussen's child, still remains unknown. In , investigators arrested and charged Joseph James DeAngelo with 13 counts of murder. Comparing online genealogy databases back to DNA collected from a crime scene of the Golden State Killer, they found a match. Once DeAngelo was identified, they took DNA from his personal items, like a discarded tissue and a swab of his car door handle , which were then matched to the samples associated with Golden State Killer crimes. Fifty years went by, and few potential leads surfaced until , when the Highsmith family decided to take DNA tests through the genealogy service 23andMe. In November , results came back that linked Melissa's biological father to a granddaughter he never knew he had.

By Andrea Cavallier For Dailymail. DNA technology has helped crack some of the most notorious cold cases and capture monsters like the Golden State Killer and the Grim Sleeper - bringing justice to the families of victims. DNA was first used to help investigate a criminal case in and since then, hundreds of cases have been solved thanks to genealogy research advances. Genetic genealogy, which is the practice of entering a DNA profile into a public database to find relatives, has emerged as a powerful tool for identifying suspects who leave DNA behind at a crime scene. Investigators can use it to construct a family tree that leads them to an otherwise unknown suspect. Here, Dailymail. Joseph James DeAngelo, now 77, a former cop who eluded authorities for years as the Golden State Killer is serving multiple consecutive life sentences for sadistic rapes and murders.

Crime cases have not always used DNA testing to solve criminal offenses. It was always difficult to explain to a jury why DNA proof could pin the crime on the accused, so it was deemed a controversial method. Today, it is much easier to convince the jury in crime cases with DNA evidence. Here are 4 crime cases that were solved using DNA testing. Albert DeSalvo, also known as the Boston Strangler, confessed to killing eleven women but later denied his confession. He was never convicted of the crimes but was sent to prison on other charges, that left people to wonder if he was the Boston Strangler. DeSalvo was killed while in prison, so they were unable to test his DNA.

Recent groundbreaking technology has revolutionized the way law enforcement investigates cold cases and has led to breaks in dozens of previously unsolved cases in alone. While not all breaks have led to arrests just yet, police have been able to use modern DNA forensics technology and genetic genealogy to link evidence from crime scenes to a certain person or group. With each breakthrough, investigators have gotten one step closer to finding answers and, in turn, a resolution.

Police said the killings of year-old Susan Tice and year-old Erin Gilmour had been tied to a still-living year-old suspect.

His DNA matched the sample collected from Chiverella's jacket in Years later, the evidence was submitted for genetic genealogy identification. DeSalvo confessed, but there was no physical evidence, so he was never convicted for the murders. Solving cold cases provides closure for families who have waited years for justice.
