DNA evidence has finally cracked open Virginia’s infamous Colonial Parkway murders after nearly four decades, linking a suspect to four brutal cold-case killings that terrorized young couples along the state’s historic scenic byways in the 1980s.
Story Highlights
- Alan Wade Wilmer was linked via DNA to four victims from the notorious 1986-1989 Colonial Parkway murder series.
- Virginia State Police confirmed Wilmer’s connection to Laurie Powell’s 1988 murder in November 2025, expanding the case to include David Knobling, Robin Edwards, and Brian Pettinger
- At least eight to ten young people were killed along or near the isolated 22-mile Colonial Parkway, with victims found in or near their vehicles showing no signs of robbery or sexual assault.
- Genetic genealogy breakthroughs after decades of investigative dead ends provide long-awaited answers for grieving families.s
DNA Breakthrough Identifies Colonial Parkway Suspect
Virginia State Police announced in November 2025 that Alan Wade Wilmer has been definitively linked through DNA evidence to the 1988 murder of Laurie Powell, whose nude, stabbed body was recovered from the James River.
Wilmer’s DNA also connects him to three additional victims: David Knobling and Robin Edwards, found shot to death at Ragged Island in September 1987, and Brian Pettinger, discovered stabbed in the James River in February 1988.
This represents a significant advancement in one of Virginia’s most haunting serial killer investigations, which has plagued families and law enforcement for nearly forty years.
The FBI announced today that new DNA technology allowed them to determine that Alan Wade Wilmer Sr. of Lancaster County, is connected to at least six murders and disappearances of young people in Virginia between 1986 and 1989.

Terror Along Virginia’s Historic Byway
The Colonial Parkway murders began in October 1986 when Rebecca Dowski, a 21-year-old College of William & Mary student, and Cathy Thomas, a 27-year-old Naval Academy graduate, were found brutally murdered in a white Honda Civic pushed down an embankment at Cheatham Annex Overlook.
Their throats were slashed with near-decapitation, rope burns covered their bodies, and diesel fuel had been poured but not ignited.
The 22-mile Colonial Parkway, connecting the historic sites of Jamestown, Williamsburg, and Yorktown through Colonial National Historical Park, became a hunting ground for a predator targeting young couples in isolated, unlit areas popular as lovers’ lanes.
Between 1986 and 1989, at least eight victims were killed in eerily similar circumstances. Vehicles were moved from crime scenes, personal belongings remained untouched, and investigators found no evidence of sexual assault or robbery.
The final confirmed Colonial Parkway case involved Annamaria Phelps and Daniel Lauer, who disappeared in September 1989 while traveling to Virginia Beach.
Their skeletonized remains were discovered weeks later at an Interstate 64 rest stop, covered with an electric blanket. Decomposition prevented definitive cause-of-death determination, though stabbing was suspected.
Jurisdictional Challenges Complicated Investigation
The sprawling nature of these crimes across National Park Service land, state highways, and rural river dumping sites created significant jurisdictional obstacles.
Local police, Virginia State Police, and the FBI all participated in investigations spanning southeastern Virginia. The killer’s selection of isolated locations near Interstate 64 suggested intimate knowledge of the region’s geography and law enforcement blind spots.
Additional linked cases emerged over time, including the May 1988 Shenandoah National Park murders of Julianne Winans and Laura Williams, whose bound bodies with slashed throats shared disturbing similarities with the Parkway victims despite the geographic distance.
Genetic Genealogy Delivers Justice Decades Later
Modern forensic techniques finally provided the breakthrough families desperately needed. Genetic genealogy, the same technology that identified the Golden State Killer, allowed investigators to trace DNA evidence preserved from the original crime scenes to Alan Wade Wilmer.
The November 2025 confirmation that Wilmer was responsible for Powell’s murder, followed by links to Knobling, Edwards, and Pettinger, demonstrates how advancing technology can resurrect cold cases that once seemed unsolvable.
While Wilmer’s current status prevents a trial, the identification provides families with long-sought answers and validates the persistence of investigators who refused to abandon these cases.
The Colonial Parkway murders left an indelible mark on Tidewater, Virginia communities, instilling fear that lingered for generations and impacting tourism along the historic corridor.
Families of victims, including relatives of the Naval Academy graduate and William & Mary student, pushed relentlessly for DNA retesting as technology advanced. Their advocacy, combined with renewed attention from true crime media, continued to pressure authorities to allocate resources to cold case investigations.
This case underscores the critical importance of preserving evidence and funding forensic advancements that can deliver justice even decades after crimes occur.
