Tragic as many homicides in the District are, most aren’t that much of a mystery. A robbery gone wrong, a drug-related beef, an innocent bystander hit by a stray bullet — the killings can be explained. Unfortunately, just the opposite is true in the killing of 32-year-old lawyer Robert Wone.

Wone was killed nearly two weeks ago, stabbed to death in a rowhouse on Swann and 15th streets, just blocks shy of the U Street corridor. But as soon as police started looking into the murder, twists and turns reminiscent of an episode of CSI or game of Clue have left them confused and searching for clues. WUSA 9 reported last week that the three residents of the house in which Wone was killed have thus far refused to speak to police, opting instead to hire defense attorneys. And on Friday, the Legal Times reported that the room where Wone was killed was cleaned before police arrived:

According to the affidavit signed by Detective William Xanten III, technicians determined that the “crime scene had been tampered with, including that the area where the victim’s body was located had been cleaned. The use of chemicals and an artificial light source showed trace blood evidence located around where the victim’s body was found. This trace blood evidence was located on the walls, floors, sofa bed and door frame of the bedroom where the decedent was killed.”

And even more suspiciously, the original claim that Wone had been killed by an intruder may be falling apart:

According to the police affidavit, one of the residents told police that an intruder had entered the house through the back door. But “there were no signs of any forced entry to the house, either through the back door or any other location,” the affidavit states. “There was nothing that appeared out of place, nothing disturbed, nothing ransacked and nothing was taken.”

These developments are as intriguing as they are tragic. Wone is still dead, and police do not seem any closer to establishing who killed him or why he was killed.
