Two Virginia state troopers were killed Saturday afternoon in a helicopter crash authorities said was linked to a white supremacist rally in Charlottesville, Va.
Lieutenant H. Jay Cullen, 48, and Trooper-Pilot Berke M.M. Bates were aboard the Bell 407 helicopter when it crashed seven miles southwest of downtown Charlottesville at 4:50 p.m.
The troopers were helping law enforcement officers monitor the nationalist rally in the area before the fatal crash. No one on the ground was injured.
"Our state police and law enforcement family at-large are mourning this tragic outcome to an already challenging day, " state police superintendent Colonel W. Steven Flaherty said.
"Lieutenant Cullen was a highly-respected professional aviator and Trooper-Pilot Bates was a welcome addition to the Aviation Unit, after a distinguished assignment as a special agent with our Bureau of Criminal Investigation. Their deaths are a tremendous loss to our agency and the Commonwealth."
In a tweet, President Donald Trump offered condolences to the families of the state troopers.
"Deepest condolences to the families and fellow officers of the VA State Police who died today. You’re all among the best this nation produces," he wrote.
The cause of the crash remains under investigation, but there is no indication of foul play.
The crash happened just a few hours after a car plowed into a crowd of people peacefully protesting against the white nationalist rally. One woman was killed and at least two dozen were hurt.
