A 27-year-old woman was killed while running through Beltway traffic late Friday night, according to the Virginia State Police. Her companion told investigators she had asked him to pull over so she could smoke.

A Subaru driver was unable to stop in time, and hit Echo D. Davis, 27, of Benson, N.C., authorities said. Witnesses told police Davis had been wandering into the highway after 10 p.m. near the Eisenhower Connector exit, before trying to bolt across the road.

Neither the Subaru driver nor Davis’s companion was charged in the incident.

“Unfortunately, it was just a very tragic situation,” said Virginia State Police Spokeswoman Corinne N. Geller. “We advise people to never pull off on a shoulder for any reason.” Even with mechanical troubles such as a flat tire, it’s better to roll off at the nearest exit, Geller said.
