After nearly four decades of families demanding justice, DNA evidence finally exposes the predator who stalked young couples on Virginia’s darkened Colonial Parkway, highlighting how federal failures to secure isolated park areas enabled a killing spree that terrorized communities for years.
Story Snapshot
- FBI links deceased suspect Alan Wade Wilmer via DNA to four murders spanning 1987-1988, expanding the notorious Colonial Parkway serial killing investigation
- Eight to ten victims, mostly young couples, were murdered between 1986 and 1989 on the unlit 22-mile Colonial Parkway through federal parkland
- Virginia State Police confirmed Wilmer’s responsibility for Laurie Powell’s 1988 murder in November 2025, with the FBI extending connections to David Knobling and Robin Edwards
- Debate continues over whether one killer committed all murders, as the modus operandi varied from strangulation to shooting to stabbing across cases
DNA Breakthrough Identifies Colonial Parkway Suspect
Virginia State Police publicly named Alan Wade Wilmer in November 2025 as responsible for the 1988 murder of twenty-year-old Laurie Powell, whose stabbed body was recovered from the James River.
The FBI subsequently extended Wilmer’s connections to the 1987 murders of David Knobling and Robin Edwards, both shot and found on Ragged Island beach. This marks the first major suspect identification in the decades-old Colonial Parkway murder series.
Wilmer, a deceased former Army reservist who lived near the crime scenes, matched witness descriptions from the original investigations. The DNA breakthrough used genetic genealogy techniques that have revolutionized cold-case investigations nationwide.
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.

Federal Park Becomes Hunting Ground for Serial Predator
Between 1986 and 1989, at least eight to ten young people were murdered along Virginia’s Colonial Parkway, a National Park Service road connecting Jamestown, Williamsburg, and Yorktown.
The 22-mile stretch became notorious as a “lovers’ lane” due to its dark, unlit conditions, which provided seclusion for couples but also made them vulnerable to attack.
The first victims, Rebecca Dowski and Cathy Thomas, were found strangled with slashed throats in October 1986, their vehicle doused in diesel fuel. The killer systematically targeted couples in vehicles, relocating cars and bodies to confuse investigators. No evidence of sexual assault or burglary emerged across cases, distinguishing these attacks from typical violent crimes.
Investigation Reveals Pattern Across Multiple Murder Scenes
The murders demonstrated consistent patterns despite varying methods of killing. Victims included Annamaria Phelps and Daniel Lauer, who vanished in September 1989 while traveling to Virginia Beach, their skeletonized remains found weeks later, with the cause of death undetermined due to decomposition.
Brian Pettinger and Laurie Powell disappeared from a Hampton dance club in December 1987; Pettinger’s body was recovered from a James River marsh while Powell’s stabbed corpse surfaced months later.
The killer exploited southeastern Virginia’s rural, wooded areas near military installations like Cheatham Annex, where federal jurisdiction complicated law enforcement coordination.
Over one hundred fingerprints from the Thomas-Dowski vehicle remain unmatched, suggesting either multiple perpetrators or extensive contamination of the evidence.
Questions Persist Over Single Killer Theory
Private investigator Steve Spingola argues the first Colonial Parkway case involving Thomas and Dowski bears no connection to subsequent murders, instead linking them to the 1981 Shenandoah National Park killings based on binding and throat-slashing similarities.
The varying modus operandi across cases—strangulation versus gunshot versus stabbing—raises legitimate questions about whether one individual committed all murders. Wilmer’s identification for Powell, Knobling, and Edwards provides closure for three families but leaves uncertainties regarding other victims.
The debate underscores how federal oversight of isolated park areas during the 1980s failed to prevent these attacks, as there were no streetlights or adequate surveillance, enabling a predator to operate freely.
This case demonstrates the critical importance of securing public lands and maintaining investigative persistence even decades after crimes occur.
