    Police identified 60-year-old Gregory Paul Vien as a potential suspect in the 1997 assaults more than two decades later through genetic genealogy, a cutting edge investigative tool used to solve countless cold cases in the past few years.

    Vien, of Livermore, was arrested earlier this month after detectives surveiling him collected a Baskin Robbins spoon he'd thrown in the trash and sent it in for forensic testing, which revealed a DNA match to the suspect in both assaults, the Alameda County District Attorney's Office said in a statement Monday.

    Gregory Vien, 60, was arrested earlier this month for two 1997 sexual assaults in Alameda County, California, after his DNA was recovered from a discarded Baskin Robbins spoon and linked to both crime scenes

    The first assault Vien is facing charges for occurred in Union City in May 1997.

    The victim was walking toward a public transit station after work when a man dragged her to a secluded area, cut her clothes off with a knife and sexually assaulted her, according to a probable cause document.

    The suspect's DNA was recovered from the victim's clothes.

    Four months later in September 1997, another woman was attacked by a man while walking past Livermore High School.

    The suspect pulled her from the bleachers, pinned her to the ground and sexually assaulted her, investigators said.

    DNA found at the second crime scene was linked to the suspect in the first attack.

    The samples were submitted to the national law enforcement database CODIS, but no match was found.

    More than 20 years later, as law enforcement agencies across the country began revisiting cold cases with genetic genealogy, investigators went back to the 1997 Livermore case and the DNA samples to a genetic lab in July.

    A chromosomal DNA profile identified Vien as a possible suspect, prompting detectives to put him under surveillance and ultimately link his DNA to the case.

    Vien was charged with multiple felony counts for the two 1997 assault cases on November 4 and was arraigned four days later.

    He is due to appear in court to enter a plea on Wednesday.

    The Livermore Police Department has said Vien have been responsible for three additional unsolved sexual assaults with similar characteristics that occurred in Livermore between 1995 and 1997.

    An investigation into those three cases is ongoing.

    Vien, a maintenance worker who's being held without bail, is scheduled to return to Alameda County Superior Court in Dublin on Wednesday to enter a plea.

    He has been charged with three counts of sexual penetration by a foreign object and two counts of forcible oral copulation, as well as 23 special allegations including committing a sex offense on a kidnapped victim, in connection with the sexual assaults of a 41-year-old woman in Union City on May 6, 1997, and a 22-year-old woman in Livermore on Sept. 15, 1997.

    Prosecutors allege that Vien was the man who attacked a 41-year-old woman in Union City on May 6, 1997 as she walked to BART after work and dragged her to a secluded area, where he sexually assaulted her. At the time, the culprit was identifiable only as a white man in his 30s.

    The just over four months later, on Sept. 15, 1997, prosecutors allege Vien attacked a 22-year-old woman while she was on a walk near Livermore High School and sexually assaulted her.

    Union City police Det. Joshua Clubb wrote in a probable cause statement that authorities finally got a break in June when the Livermore police forensics team sent the DNA sample to a private lab and a genetic genealogy search was conducted of the private database. Preliminary results allegedly identified a possible relative of the 1997 assailant.

    Livermore police soon identified Vien as their target suspect and began watching the man. The case turned when Livermore officers who were conducting extensive surveillance on Vien surreptitiously collected a Baskin-Robbins spoon that he had discarded and sent it to a DNA lab for forensic analysis, according to Clubb.

    Clubb said on Aug. 28 the lab determined that the swab from the spoon matched semen strains and sperm in the Union City rape case.

    O'Malley said DNA evidence that was collected when Vien was arrested at his home in the 100 block of Cameo Drive in Livermore on Nov. 5 also connected him to both sexual assaults.

    Livermore police said there are three additional unsolved brutal sexual assaults that occurred in Livermore between 1995 and 1997, which have similar characteristics to those in the incidents for which Vien has been charged.

    They said Vien is a long-time Livermore resident who also frequented Union City, Fremont, Hayward, San Lorenzo and San Ramon in the mid to late 1990s.

    Livermore police said anyone who has information about the unsolved cases should contact Sgt. Steve Goard at (925) 580-9585 or

    Union City police said people with information also can contact Clubb at (510) 675-5227 or

    Here is another report about the arrest in this case:

    DNA on Baskin-Robbins spoon links man to sex assaults from 22 years ago: Prosecutors

    Part of the above report:

    Genetic genealogy has been called a "game-changer" in the effort to crack cold cases. Since the arrest of the suspected "Golden State Killer" in April 2018, about 100 suspects have been identified through the technology, according to genealogy expert CeCe Moore. Just last week, the suspected Potomac River Rapist, who "terrorized" women in the Washington, D.C., area in the 1990s, was caught with genetic genealogy.

    Once Vien was identified as a potential suspect through genetic genealogy, detectives surveilled him and collected a Baskin-Robbins spoon he had discarded, according to the probable cause document.

    A defendant in two decades-old sexual assaults has been released from jail due to concerns over the coronavirus behind bars.

    Gregory Vien, 61, stands accused of sexually assaulting two women in 1997. But now, he's a free man, after his bail went from $2.5 million to zero.

    "We vehemently argued against his release and against the lowering of bail to zero," said Teresa Drenick, Alameda County district attorney's spokeswoman.

    UPDATE Livermore Cold Case Rape Suspect Gregory Vien Dies From Injuries Sustained In Nail Gun Suicide Attempt
    ''LIVERMORE (CBS SF) — A Livermore man being tried for two 1997 cold case rapes has died from injuries sustained in a suicide attempt with a nail gun, the Alameda County District Attorney announced Friday.

    In a press release issued Friday afternoon, Alameda County District Attorney Nancy E. O’Malley said the preliminary hearing against cold case rape defendant Gregory Paul Vien had been halted earlier this month when he was hospitalized following a suicide attempt where he shot himself several times with a nail gun. O’Malley said Vien succumbed to his injuries on Thursday.''
