The U.S. Park Police has confirmed the damage to the Memorial was vandalism, not an accident:
The unidentified substance that was found splashed on the Vietnam Veterans Memorial earlier this month was the result of vandalism, the U.S. Park Police said today.
Sgt. Robert Lachance, a spokesman for the Park Police, said the investigation into the incident is continuing, but the detective on the case had ruled it an act of vandalism. Lachance said he could provide no more details because the probe is still underway.
Park Service officials said they did not know what the substance was, and at first said it was unclear if it was the result of vandalism or some kind of accident.
Park Service spokesman Bill Line said today that maintenance and preservation crews were still working to remove the stains and marks, but were proceeding with caution to avoid further damage. He said the crews were trying to avoid pushing any residue into cracks or grout in the stone.
Here is the press release from the Vietnam Veterans Memorial Fund. Michelle Malkin is reporting the Fund is offering a $5,000 reward to anyone providing information leading to arrest and conviction in the case.
