A former Olympic canoeist has been indicted by a grand jury in Washington, DC, Superior Court, for allegedly damaging the Reflecting Pool in front of the Lincoln Memorial.

David Hearn was charged Thursday with one count of destruction of property with a value of more than $1,000, according to the indictment. The felony charge carries a maximum penalty of 10 years in prison, if convicted.

The indictment said a DC grand jury found that Hearn “maliciously did injure, break and destroy certain property, that is, the lining material of the Lincoln Memorial Reflecting Pool.”

US Attorney for the District of Columbia Jeanine Pirro said at a news conference Thursday that Hearn “ripped” part of the Reflecting Pool last month, and about two square feet of the pool’s sealant was damaged.

“The evidence shows, and we will prove beyond a reasonable doubt, that Hearn willfully destroyed property at the Lincoln Memorial Reflecting Pool,” Pirro said, calling it as a “deliberate act.”
