Authorities in the D.C. area are hoping a digitally produced composite sketch will help identify and convict a suspect connected to at least six sexual assaults dating back two decades.

According to WRC, federal authorities used DNA evidence to determine the suspect is a black male between 5’7″ and 5’10 with black hair, brown eyes and medium-dark complexion.

FBI investigators say the man targeted hotel housekeepers in the violent rapes, which included victims between the ages of 18 and 68. He is currently believed to be in his late 30s to late 40s.

Based on available evidence, the FBI released an image thought to reflect what the suspect would look like today.

In addition to DNA, authorities have recovered additional evidence they believe could help identify the suspect.

Among the most promising items announced by police is a red box cutter left behind at the scene of a 2002 attack in a Silver Spring, Maryland, hotel. The tool had the name “Debbie” written on it.

The following year, he left a ring behind at the scene of another attack, authorities say.

Prosecutors were able to secure an indictment against the suspect last month.

The judge’s approval came just as the statute of limitations was about to expire in two D.C. cases. It was the first time prosecutors in the nation’s capital were able to use DNA evidence alone to secure an indictment.

With a digital composite sketch added to their mounting evidence, U.S. Attorney for the District of Columbia Jessie Liu said prosecutors are “hopeful that we finally will be able to hold this serial rapist accountable for his brazen crimes.”

FBI Special Agent in Charge Matthew J. DeSarno issued a statement urging the public to help track down the suspect.

“If you recognize this person, if this box cutter or ring are familiar, if you have seen these items before, we need you to call law enforcement and provide the information,” he said. “The public’s assistance is vital in solving this case.”
