UPDATE --- Henderson County authorities identified the person who was killed after a semi truck overturned late Wednesday afternoon. Police say Leroy Gibson of North Carolina was heading northbound on the Pennyrile Parkway just south of Henderson when he apparently crossed over a very steep median and two lanes of traffic on the southbound side. Gibsons semi came to a stop in the backyard of a Henderson homeowner. Neighbors say it was raining at the time of the accident and that it sounded like thunder when the truck slammed into the yard. The truck belonged to the company Hunt Brothers. It was carrying Ragu spaghetti sauce.
