A Greenwood woman who was riding on a motorcycle died Thursday in Brown County after she was thrown from the bike and hit by a truck. Jennifer Garrison, 27, was a passenger on the motorcycle driven by 33-year-old William Lambert. Investigators say Lambert was passing cars in a no-passing zone on State Road 135 near the Morgan County line when he lost control of the bike. A pickup truck swerved to avoid the motorcycle and struck Garrison before hitting a tree. She was killed instantly.
