WASHINGTON -- An Edmond man vacationing in Washington, D.C. with his family became the witness to a shooting that locked down Capitol Hill.

Robert Drumm said he and his family had just finished sightseeing and were on their way back to Union Square when a white Mercedes came barreling towards the Capitol.

Capitol police said the driver hit two officers and crashed into a police cruiser. The 35-year-old driver then waved a gun in the air, which prompted police to shoot the man. The man died from the gunshot.

Drumm said about 10 to 15 shots were fired and he didn't realize it was gunshots until he turned and looked at his family.

"I could hear my wife yelling for them to get down. When something like that happens, I mean gunshots, it's surreal," Drumm said.

He said the entire event happened quickly, and he never felt in danger because of the swift response by police.

"It was pretty incredible with all the police there in a short amount of time," Drumm said.

He said he's glad his family is safe and his kids are definitely ready for the first day back to school.

"You know, when they talk about what you've done on summer vacation they'll have a story," Drumm said.

The Drumm family said they plan on doing a little more sightseeing tomorrow before making their way back to Oklahoma.
