Robin Margaret Edwards was 14 when she was found shot to death on September 23, 1987, at the Ragged Island Wildlife Refuge in Isle of Wight County, Virginia. Her body was discovered alongside 20-year-old David Lee Knobling’s by a beachcomber; both had been reported missing after last being seen on September 19.

Their deaths were part of a string of double homicides in the area between 1986 and 1989 often grouped with the Colonial Parkway Murders. At the time the case went cold, investigators did not have definitive forensic evidence tying these shootings to the other killings.

A major development came in January 2024 when forensic analysis identified Alan Wade Wilmer Sr. as the man responsible for the deaths of Robin Edwards and David Knobling; Wilmer had died in 2017 and therefore did not face prosecution. The posthumous identification relied on DNA matches to samples from the scenes.

If anyone knew Robin, David, or their movements in September 1987, please share what might help clarify how they came to be at Ragged Island.
