Thirteen people were killed on Virginia roadways during the five-day Thanksgiving holiday weekend, a slight increase over the previous two years, according to Virginia State Police.

Police said that between Wednesday and Sunday, three pedestrians were killed in Chesterfield, Loudoun and Stafford counties; one person was killed riding a motorcycle in Fauquier County; and one crash killed two people on Interstate 66 in Fairfax County.

Alcohol was a factor in at least three of the crashes. Five of the fatalities involved people who were not wearing seat belts; these included four drivers and one passenger.

The victims ranged in age from 17 to 71 years old. One victim was from Maryland and one victim was from Pennsylvania. All other victims were Virginia residents, police said.

According to officials, 11 people were killed on Virginia roadways during the same five-day period in 2011. In 2010, there were 10 fatalities.
