Official death certificates for filmmaker Rob Reiner and his wife Michele have confirmed the couple died within minutes of suffering numerous knife wounds at their Los Angeles residence on December 14.
Documents obtained from the Los Angeles County Medical Examiner's Office reveal that both died from "multiple sharp force injuries" inflicted "with a knife" at their Brentwood home.
The legendary director, aged 78, was pronounced dead at 3:45pm, whilst his 70-year-old wife was declared deceased just one minute later at 3:46pm.
The certificates specify that the interval between the onset of their injuries and death lasted only "minutes."

The couple's remains were cremated at Mount Sinai Mortuary on December 19, five days after their deaths.
According to the official documents, their ashes were subsequently transferred to the residence of their eldest son, Jake Reiner, who served as the informant for both death certificates.
A notable detail in the paperwork shows that whilst Rob's marital status was recorded as "married" at the time of his death, Michele's certificate lists her as "widowed" – a consequence of her husband being discovered moments before her.
