The shootings stirred memories of the Washington-area sniper shootings six years ago that killed 10 people.
The ballistic analysis by the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives linked shell casings from a Ruger .22-caliber magnum rifle to casings found near the interstate and in a 1974 AMC Gremlin owned by Slade Allen Woodson, 19, of Afton. The weapon was seized at a farm in Crozet where Woodson was arrested Friday. Authorities also charged a 16-year-old from Crozet whose name was not released.
"The motive - that's what they're trying to determine now," state police spokeswoman Corinne Geller said.
Surveillance video at the Waynesboro credit union captured a light-colored AMC Gremlin around the time shots were fired there. Police found the car Thursday afternoon, abandoned along a road.
Woodson and the 16-year-old boy each have been charged with 10 felony counts of malicious wounding, use of a firearm in the commission of a felony, shooting at an occupied vehicle and destruction of property. Woodson also faces two felony counts of shooting into an occupied dwelling and destruction of property for his role in two shootings in Waynesboro.
No additional arrests were anticipated, State Police Superintendent W. Steven Flaherty said in a statement Saturday.
