After 37 years of heartbreak, Virginia authorities finally delivered justice to a grieving family by using advanced DNA technology to solve the brutal murder of 18-year-old Laurie Ann Powell and linking her killer to a deadly crime spree that terrorized communities across the state.
Story Highlights
- DNA evidence links deceased suspect Alan Wilmer Sr. to four separate murders spanning from 1987 to 1989.
- 18-year-old Laurie Ann Powell was stabbed multiple times after disappearing while walking in Gloucester County.
- Wilmer was connected to the infamous Colonial Parkway murders that claimed David Knobling and Robin Edwards.
- Authorities are actively investigating whether Wilmer committed additional unsolved crimes across Virginia.
DNA Breakthrough Solves Decades-Old Murder
Virginia State Police announced that DNA evidence has definitively linked Alan Wilmer Sr., who died in December 2017 at age 63, to the 1988 murder of Laurie Ann Powell.
The breakthrough came 37 years after Powell was last seen walking along a road in Gloucester County on March 8, 1988. Her body was discovered nearly a month later in the Elizabeth River near Craney Island, bearing multiple stab wounds that revealed the brutal nature of her death.
Colonial Parkway Murders killer Alan Wade Wilmer, Sr. linked via DNA to murder of Laurie Ann Powell. Wilmer now linked to 4 homicides: Robin Edwards and David Knobling in 1987, Laurie Ann Powell in 1988, and Teresa Lynn Spaw Howell in 1989. https://t.co/nXi6m9gCND @MurderOver

Serial Killer Connected to Colonial Parkway Murders
Investigators determined last year that Wilmer was responsible for three other murders spanning a deadly two-year period. The victims included David Knobling and Robin Edwards in 1987, whose deaths formed part of the notorious Colonial Parkway murders series that terrorized Virginia communities.
Wilmer also killed Teresa Lynn Spaw Howell in 1989, completing a pattern of violence that authorities are now examining for potential additional victims across the region.
Family Finds Closure After Decades of Uncertainty
Powell’s sister, Cindy Kirchner, delivered an emotional tribute at Friday’s news conference, describing her sibling as “bold, brave, spontaneous, full of life” and “a true firecracker” who never apologized for being herself.
Kirchner expressed gratitude for finally receiving answers after 37 years of heartbreak and unanswered questions. The family’s long journey toward justice exemplifies the importance of never abandoning hope, even when cases grow cold and decades pass without resolution.
Ongoing Investigation Seeks Additional Victims
Virginia State Police continue investigating whether Wilmer committed additional crimes beyond the four confirmed murders. Spokesperson Robin Lawson emphasized that authorities remain committed to seeking justice for victims of other unsolved crimes throughout the state.
Captain Timothy Reibel urged the public to provide any information that could help solve remaining cold cases, noting that even seemingly minor tips could yield crucial evidence in other investigations.
Advanced Technology Delivers Long-Awaited Justice
This case demonstrates how modern forensic technology can breathe new life into cold cases that once seemed hopeless. While Wilmer escaped earthly justice by dying in 2017, the DNA evidence would have resulted in murder charges had he lived to face trial.
The successful resolution of Powell’s case offers hope to other families waiting for answers and showcases law enforcement’s dedication to pursuing justice, regardless of how much time has passed since the original crimes.
