Two people sitting on a park bench in downtown Washington were killed when an SUV veered off the road late Wednesday and struck them, officials said.

Sgt. Eduardo Delgado, a spokesman for the U.S. Park Police, said the driver of a GMC SUV was taken to a hospital with non-life-threatening injuries.

Delgado said an initial investigation shows that speed was a factor in the crash.

Officials did not immediately release the names of those involved, pending notification of their families.

The crash happened about 11:30 p.m. Wednesday at Pennsylvania Avenue and 21st Street NW in James Monroe Park, a few blocks from the Foggy Bottom Metro stop.

On Thursday morning, the park was still blocked off with police tape as Park Police cleanup crews loaded debris — including parts of the bench, branches, a bike and a cooler — into a pickup truck.

Only concrete blocks remained of the bench where the two people had been sitting.
