'Fastest woman' racing driver dies trying to break own record

Racing driver Jessi Combs, considered the "fastest woman on four wheels," was killed in a car accident trying to break her own record, police said Wednesday.

Combs's jet car crashed Tuesday in the Alvord Desert where she was pronounced dead at the scene, officers in the northwestern US state of Oregon said in a statement.

Combs, 39, earned her "fastest woman" title in 2013 when she hit 398 miles (641 kilometers) per hour, and police said the fatal crash occurred while "attempting to break" the record.

"Jessi Combs was pronounced deceased at the scene," the Harney County Sheriff's Office statement said. "The cause of the crash is unknown at this time and is currently being investigated."
