NO REMORSE, STONE-FACED NICK REINER 'SLIT PARENTS' THROATS,' ROB, MICHELLE REINER MURDERED

Nick Reiner appears in a Los Angeles courthouse on Wednesday for the first time since he is accused of killing his parents, Rob Reiner and Michele Singer Reiner. While in court, Nick Reiner, 32, appears to be wearing an all-blue vest. The only words he utters during the brief appearance are, “Yes, your honor.” His arraignment is pushed back to January 7, marking the second time it was delayed since his arrest Sunday in his parents' deaths. The Los Angeles County Medical Examiner's Office on Wednesday listed the couple's cause of death as multiple sharp force injuries. Many jump to the conclusion that the Reiners were bad parents to their middle child, and somehow responsible for their demise at their troubled son's hands. Critics highlight Nick Reiner’s early signs of addiction and meth. The teen reportedly entered rehab for around his 15th birthday.
