Twelve people were killed over the Thanksgiving holiday period in traffic crashes on Virginia highways, officials said.

Among those who died on Virginia highways was a police officer in Winchester. Officer Hunter Edwards, 30, had been with the Winchester Police Department for four years and was assigned to the patrol division. He was killed in a single-vehicle crash Saturday as he was responding to a report of a fight, officials said.

In addition to Edwards’s death, Virginia State Police said 11 others were killed from Wednesday to Sunday. Eight of those killed were drivers, two were passengers in vehicles, and one was on a motorcycle.

Last year, 14 people were killed in traffic crashes in Virginia. The 2017 toll was the highest over the Thanksgiving holiday weekend since 2013, according to the state police.

Virginia State Police said they ticketed nearly 600 people who failed to buckle their seat belts, and issued another 198 citations for child-safety-seat violations this holiday weekend. Roughly 9,000 tickets were issued for speeding and reckless driving violations, and 102 people were arrested on suspicion of driving drunk in Virginia, officials said.

Maryland State Police said there were four traffic-related deaths over the holiday weekend in the state, including an incident on the Eastern Shore where a young boy was killed.

The 6-year-old boy was killed in a car crash that appeared to be the result of a road rage incident, according to the Baltimore Sun. Officials with the state police said Kaleb Chatmon was a passenger in a pickup truck when it went off Route 13 in Wicomico County and hit a tree on Thanksgiving night.

The 55-year-old driver of the truck from Salisbury, Md., suffered critical injuries and was taken to a hospital.

According to the Sun, witnesses told police that the truck and two other vehicles appeared to be speeding and got into a road rage incident before the crash. State police said they were looking into whether drugs and alcohol were factors.

Maryland State Police said troopers made 99 drunken driving arrests and issued more than 9,000 citations and warnings for traffic-related incidents. Law enforcement also responded to more than 330 crashes and 7,300 calls for service, according to state police.
