"It may be some DNA evidence, it may be other types of evidence that are kept at our storage facilities," Kelly said. "Significant flooding has taken place, and we're still trying to sort through this and assess the total damage."
The 76th and 94th precinct station houses in Carroll Gardens and Greenpoint, central storehouses for evidence collected by the NYPD, sustained some of the most serious flooding during Sandy, police sources said.
The extent to which evidence was damaged will be "be addressed in a case by case basis," Kelly said. "What's available? Is it partially available? Is it totally destroyed? It depends on the case."
The 60th Precinct station house in Coney Island, which sits barely a quarter mile from the shore and was evacuated during the storm, was still shuttered Tuesday. Its officers were working out of the 61st Precinct station house in Sheepshead Bay.
