Legendary director and actor Rob Reiner and his wife, Michele Singer Reiner, 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 (December 15).

Romy reportedly told investigators that a relative "should be a suspect" because they're "dangerous" and suggested that the incident stemmed from a heated argument. The couple's son, Nick Reiner, was reported to be eyed as a person of interest in his parents' deaths, law enforcement sources confirmed to the New York Post.

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

Law enforcement sources initially confirmed that two people matching the couple's ages were found dead at the home, however, police hadn't publicly identified the two deceased individuals at the time.

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).
