Cold Case Detectives Identify Suspect of Unsolved Rapes and Murder; DNA and Genealogy Helped Solve the Crimes

Detectives from the Major Crimes Division – Cold Case Section have identified the suspect who committed a 1989 rape of a 53-year-old female and the 1994 rape and murder of 44-year-old Le Bich-Thuy.  The suspect, identified as Kenneth Earl Day, died in March 2017 in Upshur County, West Virginia, at the age of 52.

The two unsolved crimes in which Day has been determined to be the suspect are:

  • Rape
    • On June 25, 1989, at approximately 10:15 p.m., the 52-year-old victim was walking on Lewis Avenue in Rockville when the suspect approached her from behind, assaulted her, and raped her. Suspect DNA evidence was recovered.


  • Rape and Homicide
    • On October 3, 1994, Le Bich-Thuy, age 42, was located deceased to the side of her home in the 1600 block of Martha Terrace in Rockville. The investigation by detectives revealed that Le Bich-Thuy had been assaulted, raped, and then strangled.  Investigators further determined that Le Bich-Thuy was last known to be alive at approximately 10:00 p.m. on September 28, 1994 as she left the Twinbrook Metro Station in Rockville.  Suspect DNA evidence was recovered.

During the investigation of these crimes, an analysis of the suspect DNA left at these two scenes determined that the same suspect committed both rapes and murder.  The suspect’s DNA was entered into a national DNA database (Combined DNA Index System – CODIS) but there was no match.  Despite extensive investigative efforts, these cases remained unsolved.

In 2017, Cold Case detectives sought the services of Parabon NanoLabs (Parabon), a DNA technology company in Virginia that specializes in DNA phenotyping, or the process of predicting physical appearance and ancestry from unidentified DNA evidence. Using the suspect’s DNA left at these scenes, Parabon’s Shapshot DNA Phenotyping Service produced what is referred to as a Snapshot composite depicting how the suspect in these cases may have looked and predicting his ancestry.  In hopes of generating new leads in these cases, detectives released the composite to the public and hoped that someone would recognize him.

More recently, Parabon submitted a genetic data profile of the suspect’s DNA to the publicly available genetic genealogy database, GEDmatch, in order to potentially find individuals who shared a significant amount of DNA with the unknown suspect.

Additional investigation, which included genealogy research, was then conducted by Cold Case investigators and led to the identification of Day as the suspect of these rapes and murder.

It was determined that Day had died in Upshur County, West Virginia, in March 2017.  Detectives obtained a sample of Day’s DNA taken from his autopsy.  The Montgomery County Department of Police – Crime Laboratory processed Day’s DNA and determined that it was a positive match to the suspect’s DNA profile taken as evidence from both crime scenes.

At this time, the Cold Case Section continues to investigate Day’s possible involvement in other unsolved crimes.  Photographs of Kenneth Earl Day taken at various dates and a list of Day’s prior known addresses with the approximate dates he lived at those locations are below.
