The police in Maryland, hope to track down a rapist and killer who struck decades ago with an image created using his own DNA. After 42-year-old Le Bich-Thuy was raped and strangled after leaving Rockville’s Twinbrook Metro station, in 1994, DNA was recovered from the scene was found to match the DNA in the 1989 rape of a 52-year-old woman who allegedly left the same station, reports the Washington Post.

But “I don’t think he did this only two or three times. This man was aimed at women in that area for at least five years,” says Sgt.

Chris Homrock, pointing to a case in which a woman escaped an attempted rapist days for Bich-Thuy ‘ s murder. To finally catch the attacker, the police turned to Parabon NanoLabs, Virginia-based company that specializes in DNA phenotyping, reports Bethesda Magazine.

Two computer-generated images are created on the basis of predictions of the suspicious origin, eye color, hair color, skin color, freckles, and the shape of the face. Released Monday, she showed how the suspect—white, with blue eyes and no freckles—would have appeared at the age of 25 and 45.

In a statement, per WTOP, Montgomery County police stress the composite “scientific approaches of appearance on the basis of DNA and probably are not exact replicas of the appearance.” Still, anyone who recognizes the man is asked to call the Major Crimes Division.

“We are looking for new information, what these images might prompt someone to remember,” says Homrock, and notes “the common theme of these cases is they all start at the Twinbrook Metro.” A reward of $10,000 is offered for information that leads to an arrest, reports Fox 5.

(In another cold case, police used Twitter in a new way.)
