Untitled2Loudoun County Sheriff’s Office (LCSO) Cold Case Detectives are utilizing advances in DNA technology to help solve a nearly 30-year-old sexual assault case.

Using DNA evidence from this investigation, detectives sought the services of Parabon NanoLabs, a DNA technology company in Virginia that provides a DNA phenotyping service, called Snapshot™, which predicts the physical appearance and ancestry of a suspect from unidentified DNA evidence.

Snapshot produced a composite image of the suspect with these trait predictions that LCSO detectives hope will assist with their investigation.

The investigation stems from the abduction and sexual assault of a 9-year-old Sterling girl on June 26, 1987.

Around 4 a.m., Loudoun County Sheriff’s Office responded to the 200 Block of E. Poplar Road where the victim reported that an unidentified male broke into her residence, abducted her and sexually assaulted her.

The evidence collected at the time of the assault and advancements in DNA technology have enabled detectives to develop a composite profile of the suspect.

Snapshot predictions are made for ancestry, eye color, hair color, skin color, freckling and face shape.

Above is a DNA composite profile of a suspect in a 1987 abduction and sexual assault in Sterling. The composite profiles are scientific approximations of appearance based on DNA, and are not likely to be exact replicas of appearance. The composite profile depicts what the suspect may have looked like at 25-years of age and at 50-years of age.

By combining these attributes of appearance, Snapshot composites were produced that depict what the suspect may have looked like at 25-years of age and at 50-years of age.

It is important to note that Snapshot composites are scientific approximations of appearance based on DNA, and are not likely to be exact replicas of appearance.

At the time of the assault, the victim described the suspect as:

  • white male
  • thin build
  • 6’ 3”
  • brown hair
  • mustache.
