A Hart County High School Senior died Thursday after a two-vehicle collision on northbound I-65 just north of Munfordville.  Tributes began circulating on social media for the family of Schyler Oldham after he was identified as the victim in the wreck which occurred around 11am local time near Mile Marker 68. Oldham was a member of the Raider Football Team and the Varsity Cheerleading Squad.  The incident was a secondary crash to an earlier wreck near Mile Marker 74.  A third crash involving two semis also occurred near Exit 65.  The string of collisions happened as rain moved through the area early Thursday causing major traffic backups on the interstate and US 31W. Clearing the initial wreck took around nine hours as towing and recovery crews had to off-load hazardous materials from the involved commercial vehicle before clearing the roadway.  All lanes of the interstate were open by 4pm.
