A Kershaw County Public Works employee died in a single-car collision when his 1996 Dodge pickup hydroplaned while traveling westbound on I-20 Sunday morning. Kershaw County Coroner David West identified the deceased as Jeffery B. Youngren, 42, of Elgin, and said he was a county employee. West did not know if Youngren was on his way to or from any work for the county, but that he was driving his own vehicle.
