Former U.S. Olympian and canoeist David Hearn is indicted on a felony destruction-of-property charge in connection with alleged vandalism at Washington, D.C.’s Lincoln Memorial Reflecting Pool. Multiple outlets report that U.S. Attorney Jeanine Pirro describes the alleged act as a deliberate effort to damage the pool’s newly installed lining or sealant. The indictment and related court records state that Hearn is accused of maliciously breaking or tearing up material on the bottom of the Reflecting Pool on June 19. CBS News and other reports specify the area as roughly two feet, or about two square feet, of blue lining that was removed.

If convicted, Hearn faces up to 10 years in prison, according to reports that cite the potential maximum penalty for the felony charge. Several outlets also note that the Reflecting Pool renovation has become a political issue in Washington, with controversy involving the project’s cost and performance. The case is proceeding through the court system, with Hearn’s alleged conduct and the extent of the damage central to the prosecution’s claim.
