Reiner, 32, charged with two counts of first-degree murder after parents were stabbed to death in December

Nick Reiner pleaded not guilty to two counts of first-degree murder in the killing of his parents Rob Reiner and Michele Singer Reiner.

His new attorney, public defender Kimberly Greene, entered the plea during arraignment in the case on Monday morning, while Reiner was behind glass in the Los Angeles courtroom.

Reiner was standing in an enclosed custody area and wore brown jail clothes, rather than a suicide prevention smock like he wore during an appearance in December, the Associated Press reported.

A judge had postponed the legal proceedings last month after his last attorney withdrew from the case and was replaced by a public defender. Reiner’s former attorney, Alan Jackson, said at the time that he could not share why he was stepping down, but that his client was not guilty.
