GREENVILLE, S.C. - Authorities say a man on a motorcycle and a pedestrian have both died in an accident in Greenville.

Troopers say the wreck happened on U.S. 123 west of downtown around 12:15 p.m. Friday. They haven't determined what led to the collision.

The Greenville County Coroner's Office says it is not releasing the identities of the men because their families have not been notified.
