Three people, two on motorcycles, were killed in crashes in the Washington area over the holiday weekend, including a popular coach at a Northern Virginia athletic and cheer organization.

The coach, identified as Dion Bagby, of Vienna, was affiliated with a cheer group for the Baltimore Ravens as well as with Virginia’s Infinity All-Star group.

“The entire Ravens family is in mourning,” said Chad Steele, a team spokesman.

A message on Infinity’s Facebook page said the group had “lost someone very special” in the Friday collision on Route 15 in Frederick County, Md.

Many people provided personal comments on the site, with several calling Bagby “an amazing coach.”

A biography on Infinity’s site said he had been a wrestler who switched to cheerleading in high school and was on a championship team at the University of Louisville.

In the other motorcycle death, Stephen M. Croft, 26, of Dumfries, died Thursday in a crash in that area, Prince William County police said.

Police said he was passing another motorcycle and collided with an oncoming vehicle.

In the last fatality, a motorist died in a three-vehicle crash Sunday in the Fort Washington area of Prince George’s County, said Officer Nicole Hubbard, a police spokeswoman. The crash occurred about 4:15 p.m. on Route 210, near Palmer Road, she said.
