Alan W. Wilmer Sr., who died at 63 years old in Lancaster County, VA, is believed to have slain David L. Knobling, 20, Robin M. Edwards, 14, and Teresa Lynn Spaw Howell, 29, Virginia State Police announced on Jan. 8.

If Wilmer were to be alive, charges would be filed against him in the thre homicides, both the Isle of Wight County and City of Hampton Commonwealth’s attorneys confirm.

ABOUT WILMER:

Wilmer had no felonies on his criminal record, so his DNA had never been obtained until it was necessary for identification purposes following his death, state police said. The Virginia Department of Forensic Science in 2023 issued a “Certificate of Analysis” confirming a genetic match to Wilmer based on evidence collected from the Isle of Wight County and City of Hampton homicide victims.

Wilmer was 5’5 in height, muscular and weighed approximately 165 pounds. He had sandy-brown hair, blue eyes and would sport a close-cropped beard. Wilmer drove a distinctive, blue 1966 Dodge Fargo pickup truck with the Virginia license plate “EM-RAW.” The Dodge was just one of several pickup trucks Wilmer was known to drive in the 1980s and early 1990s.

He also had a small commercial fishing boat, named the Denni Wade. It was a 1976 custom-built, wooden boat. He would dock at marinas in the counties of Gloucester and Middlesex, and around the Northern Neck. His trade during the 1980s was as a fisherman, farming mainly clams and oysters. He also ran a business called Better Tree Service. He was an avid hunter and belonged to at least one hunt club located in the Middle Peninsula region.

ABOUT THE HOMICIDES

Knobling, 20, and Edwards, 14, were found shot to death on Sept. 23, 1987, along the shoreline of the Ragged Island Wildlife Management and Refuge Area on the south bank of the James River in Isle of Wight County. Edwards had been sexually assaulted. The two were last seen alive together the night of Sept. 19, 1987. The next day, Sept. 20, 1987, Knobling’s blue 1966 Dodge Fargo pickup truck with the Virginia license plate “EM-RAW” truck was found abandoned in the Ragged Island parking lot. 

Over time, the Isle of Wight County double homicide became known as one of four separate double homicides that spanned from 1986 through 1989 and were coined the “Colonial Parkway Murders.”

Howell was last seen alive on July 1, 1989, at approximately 2:30 a.m. in the City of Hampton outside of the Zodiac Club at 207 E. Mercury Boulevard. Later that same day, at approximately 10:10 a.m., a construction crew working in the 500 block of Butler Farm Road discovered women’s clothing near their work site. 

An unidentified woman was found dead shortly afterwards in the nearby wood line. 

On July 4, 1989, a missing person report was filed in York County, leading to the identification of the female victim as Teresa Lynn Howell, 29, of Hampton, Va. Howell had been sexually assaulted and died as a result of strangulation. The Zodiac Club is no longer in existence today.
