UPDATE: Cold Case Squad Solves 1998 Sexual Assault

Mason Police District – Detectives from our Major Crimes Bureau’s Cold Case Squad have solved a sexual assault that occurred more than two decades ago. In August of 1998, a 32-year-old woman was sexually assaulted in the 7200 block of Parkwood Court in the West Falls Church section of Fairfax County. The suspect posed as an exterminator and threatened the victim with a gun while forcing his way into her home. The victim ultimately escaped by jumping two stories from a balcony.

DNA and fingerprints were collected from the scene. Detectives entered them into nationwide databases but the identity of the offender remained unknown.

Cold Case detectives continued to pursue leads and in early 2019, resubmitted the suspect’s DNA and fingerprints hoping that newly emerged technology would reveal the suspect’s identity. Several months later, detectives received a fingerprint hit for Juan Johnson, from Maryland.

Detectives learned that Johnson died in 2014 at the age of 48 but a blood sample remained on file in Baltimore, Maryland, from an autopsy conducted upon his death. The Virginia Department of Forensic Science examined the blood and matched it to Johnson’s DNA collected from the scene.

Detectives worked tirelessly to solve this case and bring resolution to the victim. Victim specialists from our Victim Services Division have been assigned to ensure that the victim receives appropriate resources and assistance.

Detectives learned that Johnson may have been responsible for a similar case that occurred in Arlington County a week prior. DNA from that case was recently submitted and matched Johnson’s profile.

“This case and our tireless efforts to seek justice and locate the offender is an example that the Major Crimes detectives never give up and always seek justice”, said Major Ed O’Carroll, Bureau Commander, Major Crimes. “I am proud of the work of the Cold Case detectives and all members of the FCPD detective bureau for how caring and committed they are to seek closure for the victims involved in these important cases.”
