The cause of Rob Reiner's death and his family, Michele Singer, was discovered four weeks after their death in their Brentwood, Los Angeles, home and a flurry of rumors.

The couple died from "multiple attack wounds" or" sharpening," according to the Los Angeles County Medical Examiner's information.

The actor's boy, 32-year-old Nick Reiner, will be fully charged in the deaths of the couple, according to District Attorney Nathan Hochman at a press conference along with Los Angeles Police Chief Jim McDonnell.

According to reports, prosecutors intend to bring two counts of first-degree death with a few counts of many homicides in addition. Additionally, they will contain a special charge that he used a deadly weapon ( a knife ).

Hochman stated in a press conference that the prosecution of these family member cases is one of the most challenging and terrible cases this office has ever faced because the crimes involved were intimate and frequently brutal.

The day of Rob Reiner's death, there were some conflicts between his brother Nick and Rob Reiner.

Rob Reiner, his family Michele, and their kids attended a Christmas party co-hosted by comedian ConanO'Brien, according to testimony obtained by The New York Times from a family-related source.

Nick Reiner allegedly displayed behavior that the cause called "erratic," which presumably caused the evening to turn out an unexpected way. The filmmaker, for his part, officially reprimanded him and said that his behavior was unacceptable for a visitor to someone else's home. One of the guests ( who preferred to remain anonymous ) claimed that the event was being inflated despite reports that Rob and Nick had a heated discussion during the party. He further stated that Nick Reiner's behavior at the party was not uncommon for the Reiner household, who had grown to be quite averse over the years.
