Accident near Auburn,NE

To Everyone: I am writing this thread in hopes that someone out there can help. I'm a trucker also, which makes this tough to do but here goes. On the evening of Feb 27th, I guess around 8PM, on hwy 136 east of Auburn,NE in southeast NE a 69 year old lady was sruck and killed as she was getting her mail out of the box along the hwy. It was a VERY ugly scene as you can imagine, but was more than likely just an accident until he left the scene. They have some VERY good proof that he stopped and got out and looked at what he hit and then left.[I can't say why they know, but trust me they know],so what started out as just a bad accident probaly turned into a crime with him leaving. They think he had some damage to his right front corner and maybe stopped at a truck stop at Rock Port,MO and got a new headlight. They have video from security cameras in town that show a light colored truck[I think they said Kenworth,not for sure on that] about the right time going east out of town, don't know if they got any markings off the truck or not. If anyone remembers anything at all or knows anything about this please PM me or call Nemaha County Sheriff office at 402-274-3139. To bad things like this happen and give all of us black eye. Thanks in advance for your help.
