The Delaware State Police Collision Reconstruction Unit is investigating a fatal motor vehicle crash that occurred on Friday, Dec. 22, at the intersection of Airport at Old Landing Roads in Rehoboth Beach.

Around 7 p.m., a Rehoboth Beach man was operating a 2008 Honda Accord, traveling northbound on Airport Road and approaching the intersection at Old Landing Road.
