The Los Angeles Police Department confirmed that legendary director and actor Rob Reiner and his wife Michele Singer Reiner's son, Nick, was arrested and "responsible" for their deaths in a news release shared on Monday (December 15).

"It was determined that the Reiners were the victims of homicide," the news release states. "The investigation further revealed that Nick Reiner, the 32-year-old son of Robert and Michele Reiner, was responsible for their deaths. Nick Reiner was located and arrested at approximately 9:15 p.m. He was booked for murder and remains in custody with no bail, under Booking Number 7133668."

The Reiners were reportedly found with their throats slit by their daughter, Romy, who told police that a "dangerous" relative should be the suspect in their deaths, sources with knowledge of the situation confirmed to TMZ on Monday. Romy reportedly suggested that the incident stemmed from a heated argument.

Nick, 32, has publicly acknowledged his issues with drug addition and homelessness in the past. Rob and Michele Reiner were reported to also have stab wounds to multiple other parts of their bodies, sources with knowledge of the situation confirmed to the New York Post.

Reiner, the son of producer, writer and actor Carl Reiner and actress and singer Estelle Reiner, initially gained national prominence playing Mike 'Meathead' Stivic on All in the Family and is credit with numerous acting roles during a career that spanned seven decades. The New York City native made his directorial debut with the heavy metal mockumentary This Is Spinal Tap (1984) -- having released a sequel earlier this year -- which was followed up by The Sure Thing (1985), Stand By Me (1986), The Princess Bride (1987), When Harry Met Sally...(1989), Misery (1990) and A Few Good Men (1992).
