Rob, Michele Reiner death investigation unravels upsetting details

Rob Reiner and Michele Singer's death investigation is uncovering further details deepening the grief of the deceased couple's fans.

Authorities confirmed that the couple was found slain in their Brentwood home just a day after attending Conan O’Brien’s Christmas party with Nick.

According to reports by The Hollywood Reporter, Nick had not been invited to the gathering initially.

However, When Harry Met Sally filmmaker and his actress wife had asked the host if their son could tag along.

The reason for taking him to the party was his increasingly extreme and stressful behavior”.

It had “grown degrees even more concerning in recent weeks.”

Rob and Michele were 'reluctant' to leave him alone in the guest house of their home where he had been living under 'watchful supervision'.

However, Nick's behaviour ended up being a nuisance at the holiday party.

Reportedly, Nick asked everyone their first name, last name and if they were famous.

These bizarre questions resulted into a tense encounter with Saturday Night Live alum Bill Hader followed by Nick 'storming off'.

The Stand By Me director and Michele after a loud argument with their son apologized to O'Brien and left the party early.
