Two people killed in a single-car crash early Sunday have been identified as twin brothers from Leesburg, Va.

Aaron W. Henry and Vincent B. Henry, both 26, died at the scene of the accident, one of several fatal crashes to occur in Loudoun over the weekend, according to police.

The accident occurred shortly after 1:30 a.m. Sunday near Evergreen Mills and Reservoir roads in Loudoun County, authorities said. Their 1994 Ford Explorer was headed northbound on Evergreen Mills Road when it came to a curve, crossed the center line, ran off the left side of the road and into a tree, according to police.

The impact of the crash caused the SUV to catch fire, and the vehicle was quickly engulfed in flames, police said.

The crash remains under investigation, but speed was determined to be a factor, according to police.
