Ten D.C. police officers flew home from Puerto Rico and they're still shocked by what they saw during a week helping the American citizens there.

D.C. Police Chief Peter Newsham says he's feeling an overwhelming sense of relief at having his officers home.

They brought back video of Puerto Rican police officers wading out of their flooded police station in chest deep water, and pictures of frightened old people who had been without food or water until the officers arrived.

The D.C. officers spent long days helping others and then sometimes went looking for their own relatives at night.

The DC Air National Guard flew the officers to Puerto Rico and back. And the Metropolitan Police Department gave them a week of paid leave to help.

The officers dug into their own pockets to pay for much of the food, water, and medical supplies they gave to people in desperate need.
