Two years after a Fairfax County car-wash owner was killed, police are still seeking leads.

Yong Suk Yun, 61, was killed on Oct. 7, 2010 at his Fairfax Station home, located at 5781 Ladues End Court, according to the Fairfax County Police Department. He owned the Dr. Wash in Chantilly, and detectives believe his slaying stemmed from a robbery.

The Washington Post reported that Yun had been stabbed multiple times in the upper body.

As part of the investigation, police have interviewed more than 100 people and watched over 100 hours of video, police officials said. They also made a Korean-language video in order to reach out to non-English speakers.

A $70,000 reward is being offered for information leading to an arrest in this case.

"We are committed to solving this murder and continue our plea to the community for information," said lead detective Connie Morris.
