WASHINGTON - An arrest has been made in the murder of a northern Virginia attorney, who was killed in a Dupont Circle townhome August 2, 2006.

Sources confirm for ABC 7/NewsChannel 8 that Dylan Ward has been taken into custody in Florida on an obstruction of justice charge in connection with the murder of Robert Wone.

Wone was spending the night at the home of his friends, Joseph Price and his domestic partner Victor Zaborsky. Also living at the home was Dylan Ward. The three men, who were at the home the night of the murder, told police they believed an intruder entered the Swann Street home in NW and stabbed Wone to death while the three slept in their bedrooms. Wone was staying at the D.C. house because he had worked late and didn't want to drive back to his Vienna home.

Police say there was no sign of forced entry and there was evidence the crime scene had been altered before investigators arrived. Wone was stabbed with a butcher knife taken from the kitchen.

In 2007, the Washington Post reported investigators said they did not get full cooperation from the three residents who were home at the time. "There's no one who wants the police to be able to find the evidence and arrest the intruder who came in and killed Robert Wone more than the three men who lived inside the home," said Attorney David Schertler. Attorneys for the three residents released a joint statement in 2007 saying the men are "puzzled and concerned regarding the false accusation that they have somehow withheld information from the police."

An attorney says the three residents submitted to 20 hours of taped police interviews and gave DNA, fingerprint, and hair samples.

"I always had a sense that this kind of killing was different from a lot of the other stuff that's going on in the city. I never felt there was, you know, a real danger for everybody else in the neighborhood. It's definitely a relief," said area resident Anke Ortlepp. "It's a relief. It's always good to know if someone got killed, who did it and it's going to be a relief for the family," said Ortlepp.

At a news conference in 2007, Wone's wife, Kathy, spoke directly to the Killer: "I realize that I also grieve deeply for the loss of your own life. Having a murder on your conscience is no small load to carry."

Ward, who moved to Miami, was charged with obstruction of justice in the Wore murder. D.C. Police Chief Kathy Lanier said she is happy with Ward's arrest, but said it does not close the Wone murder case. "Our goal is to arrest the murderer. That is our goal. So it's fair to say we will continue to investigate very aggressively until we have the murderer in custody."

Ward's attorney, Dave Schertler, released a statement saying, "The prosecution's case is pure fantasy. My client is innocent. There is no basis for these charged and we are prepared to go to trial to prove it."

Counsel to the Wone family also released a statement saying, "Robert's family, assisted by counsel, will continue to do everything in their power to ensure that all those responsible for his murder and the cover-up relating to his murder are brought to justice." The statement continues, "Robert was a remarkable person. He was a loving husband, son, and brother; an accomplished lawyer; and a generous contributor of his time, energy, and resources to the community at large and to those in need. His tragic loss continues to be felt everyday by many."

Lanier said although it's been a cold case, police investigations take time. "Sometimes we have to ask for the public's patience because when we make an arrest.. it takes a lot of investigative work. We want to make sure that we do the job and do it right. We have not closed the murder and the investigation continues."
