A New Jersey juror on a high-profile murder trial was dismissed after an inappropriate Facebook post. “Sitting on the jury LMAO [laughing my ass off]," the post read. It's thrown the trial of Liam McAtasney into chaos, with his lawyer insisting a mistrial be declared in the wake of the comment. The judge denied that request. McAtasney is accused of killing Sarah Stern in December 2016 and then enlisting his roommate to help dispose of her body by throwing it over a bridge, prosecutors claim.
