Nick, 32, was due in court today after being charged with two counts of first-degree murder regarding the deaths of his parents, Rob and Michele Reiner.
Rob is best known for directing cult classics like When Harry Met Sally, Stand By Me, and This Is Spinal Tap.
There was speculation the 32-year-old suspect was going to be in court yesterday (December 16), but his lawyer Alan Jackson explained that his client had not yet been medically cleared to be transported to the courthouse. He called this 'a procedural issue'.
Nick is currently being held without bail. His bond was initially set at $4,000,000 but this was changed.
The Los Angeles County District Attorney's Office has already announced its charges against Nick.
District Attorney Hochman said in a statement: "Prosecuting cases involving family violence are some of the most challenging and heart-wrenching we face because of the intimate and often brutal nature of the crime.
"Rob Reiner was one of the greatest filmmakers of his generation. His murder and his wife of more than 35 years, Michele Singer Reiner’s murder, are shocking and tragic. We owe it to their memory to pursue justice and accountability for the lives that were taken."
Now, following his first court appearance today, Nick's lawyer Jackson addressed the press and pleaded to the public that they don't jump to conclusions.
"We all recognise the tragedy, there's very complex and serious issues that are associated with this case," he said.
Nick Reiner has been charged with the murder of his parents.
Jackson continued: "We ask that you allow the system to move forward in the way it was designed to move forward. Not with a rush to judgement, not with jumping to conclusions but with restraint and with dignity and with the respect that this system deserves and the family deserve."
When in court Nick waived his right to enter into a plea. He was not in view of the cameras and spoke very little during his brief appearance. Nick simply said 'yes, your honour' when asked by Judge Theresa McGonigle if he understood he has the right to a speedy trial, BBC reports.
