and hurt several other people. this happened on the new jersey turnpike halfway between new york and philly. since then somebody claiming to be kevin roper tweeted about this case. several media organizations report it is in fact he, though i can't confirm that. one of the most recent tweets reads i thought in our country we had the right to be innocent until proven guilty. that doesn't sell newspapers and get website hits. of course he is innocent until proven guilty. for its part, walmart claims roper is not on social media and this is a bust and he was following federal safety regulations when the crash happened in the first place. we get more on this from our newsroom in new york city. >> you mentioned prosecutors claim he was awake for more than 24 hours and that's an important detail under new jersey law. if a driver has been awake for more than 24 hours, it can legally speak to whether he was driving recklessly. we've not been able to contact kevin roper or his attorney but that person who claims to be him on twitter denies after saying he was awake for 24 hours
