What We Know About Rob Reiner's Son Nick

News of the tragic death of beloved director, writer, and actor Rob Reiner and his wife, Michele Singer, has taken the world by storm. The couple was murdered in their LA home on December 14. And, while there is still quite a bit of mystery surrounding their deaths, the LAPD has announced that their son, Nick Reiner, has been charged with murder and is currently being held without bail. Their son's potential involvement in this sudden and horrific tragedy has inspired many questions about Nick and his relationship with his family.

Rob and Michele have three children together: Nick, his older brother Jake, and his younger sister Romy. Nick spent years struggling with drug addiction. His drug use landed him in rehab on many occasions, and he found himself experiencing homelessness in the midst of it all. In 2015, Rob, who has directed many beloved films from "The Princess Bride" to "When Harry Met Sally," went on to direct "Being Charlie." The movie was co-written by Nick along with Matt Elisofon, who also dealt with addiction. This was reflected in the film's titular character, Charlie. Charlie also struggled with addiction, and like Nick, had a famous dad. "It's not my life," Nick told People about the movie. Still, he noted, "I went to a lot of these places, so I had a lot of these stories."

Making "Being Charlie" was a complicated experience for Rob and Nick Reiner to embark on together. "It was very, very hard going through it the first time, with these painful and difficult highs and lows," Rob told the LA Times when the film  premiered. "And then making the movie dredged it all up again," he said. Ultimately, though, the family hoped that it would help other families who were dealing with similar struggles. "It's for them. But really, it's for us," Rob explained. He added, "To be honest, by the time we got to the point of making the movie, it didn't matter if we actually did. Because our relationship had gotten so much closer."

At this time, it's unclear what the Reiner family may have been going through at the time of Rob and Michele Reiner's shocking deaths. Yet, according to TMZ, sources close to the family claim that Michele had been confiding in friends in the months leading up to their murders. She allegedly claimed that she and Rob were struggling to help Nick through his substance abuse and mental health issues, noting, "We've tried everything." According to the sources, Rob and Nick got into a "very loud argument" at Conan O'Brien's Christmas party the night before the tragedy.
