Rob Reiner's son Nick Reiner was "entitled" and "wanted to live a life that didn't exist," a source close to the family tells PEOPLE. The 32-year-old, now charged with killing his parents, previously spoke about having "no identity" and "no passions" growing up in the shadow of a famous father.

Billy Crystal, Larry David, Martin Short, and more stars shared a heartfelt tribute for Rob and Michelle Reiner, who were killed in a fatal stabbing.

Reiner and his wife, Michele Singer Reiner, were found dead inside their Brentwood, Calif. home on Sunday afternoon at 78 and 68, respectively. The Los Angeles Police Department said at the time that their deaths were being investigated as a homicide, but that they had not identified a suspect and no one had been detained.
