One person was missing after flash floods rampaged on Sunday through the downtown of a Maryland community that was devastated by flooding nearly two years ago.

The community, Ellicott City, about 15 miles west of Baltimore, experienced floodwaters six feet deep in some places, according to witnesses. Heavy rains that started around 3 p.m. prompted residents to seek shelter in upper floors and the authorities to dispatch swift-water rescue teams.

On Monday, officials said they were searching for Eddison A. Hermond, 39, who was last seen around 5:20 p.m. on Sunday in a parking lot, Mark Miller, a spokesman for Howard County, said.
