Aug. 12 (UPI) -- Nick Reiner, the son of Hollywood director Rob Reiner and Michele Reiner, pleaded not guilty to new charges Wednesday in the murder of his parents December in their California home.

Reiner was indicted by a grand jury last month on new charges that replace the original murder case. These charges add a new special circumstance allegation of murder by means of lying in wait.

The additional allegation makes Reiner eligible for the death penalty, but prosecutors have not said if they will seek it.

"This was a profound betrayal by someone who was loved and trusted by the very people he is accused of killing," Nathan Hochman, Los Angeles County district attorney, said in a statement.
