Story Highlights

- Wilmer, who died in 2017, was previously connected to three other murders, including the Colonial Parkway cases.
- Powell’s family receives closure after nearly four decades of heartbreak and unanswered questions.

DNA Breakthrough Solves Decades-Old Murder
Virginia State Police announced that DNA evidence has linked Alan Wilmer Sr. to the 1988 murder of Laurie Ann Powell, an 18-year-old who was last seen walking along a Gloucester County road on March 8, 1988.
Powell’s body was discovered nearly a month later in the Elizabeth River near Craney Island, bearing multiple stab wounds. Wilmer, who died at age 63 in December 2017, would face murder charges if alive today, authorities stated during Friday’s press conference.

Connection to Colonial Parkway Serial Killings
The breakthrough in Powell’s case represents part of a larger pattern of violence. Investigators previously determined that Wilmer was responsible for three other murders: David Knobling and Robin Edwards in 1987, and Teresa Lynn Spaw Howell in 1989.
The Knobling and Edwards murders formed part of “a series of double murders collectively known as the Colonial Parkway murders,” according to Virginia State Police spokesperson Robin Lawson. This connection suggests Wilmer operated as a serial killer across multiple years in the Virginia region.
Ongoing Investigation into Additional Crimes
Law enforcement officials are actively investigating whether Wilmer committed additional crimes beyond the four murders already attributed to him.
Virginia State Police Captain Timothy Reibel emphasized that “any tip could be useful in solving other cold cases,” highlighting the department’s commitment to uncovering the full scope of Wilmer’s criminal activities. The systematic approach to linking cold cases through DNA evidence demonstrates how modern forensic techniques can finally deliver justice for decades-old crimes that once seemed unsolvable.
Family Finds Peace After Decades of Pain
Laurie Ann Powell’s sister, Cindy Kirchner, delivered an emotional tribute at the press conference, describing her sibling as someone who “didn’t wait for life to happen — she made it happen.” Kirchner remembered Powell as “bold, brave, spontaneous, full of life, witty, smart, and beautifully herself. A true firecracker.”
The family’s 37-year journey toward answers finally concluded with this DNA breakthrough, providing closure while honoring the memory of a young woman whose life was tragically cut short by a predator who continued killing for years afterward.
