State police in Maryland and Pennsylvania were investigating two fatal vehicle accidents on Saturday.
A Hagerstown woman died Saturday morning following a single-vehicle collision on Interstate 70 near Hollow Road in Frederick County, according to a Maryland State Police press release.
Alison Costa, 23, was westbound on Interstate 70 just after midnight when the 2006 Toyota Solara she was driving left the road and struck an embankment, according to the release.
Police do not know what caused the vehicle to leave the road, although speed might have been a contributing factor, according to the release.
