Rob Reiner and wife Michele's death certificates released

On Sunday, Dec. 14, police discovered the bodies of Rob and Michele in the primary bedroom of their home in Brentwood, California. 

The couple's son, Nick, was quickly named a person of interest in the investigation, and hours later, around 9:15 p.m. local time that same day, he was arrested.

On Dec. 16, authorities charged Nick in the double homicide of his parents. He was charged with two counts of first-degree murder with a special circumstance of multiple murders.

"He also faces a special allegation that he personally used a dangerous and deadly weapon, that being a knife," Los Angeles County District Attorney Nathan Hochman said during a press conference. "These charges carry a maximum sentence of life in prison without the possibility of parole, or the death penalty."

Nick made his first court appearance in the case on Dec. 17, where his lawyer, famed defense attorney Alan Jackson, requested a continuance. His arraignment is now set for Jan. 7.

On Monday, Dec. 22, the Reiners' children, Romy and Jake, spoke out about their parents, and the support they've received. 

"They will share information about a memorial service honoring their parents at a later date," the spokesperson added.

Their latest statement comes after Romy and Jake broke their silence on Dec. 17, three days after their parent's murder.

"We are grateful for the outpouring of condolences, kindness, and support we have received not only from family and friends but people from all walks of life. We now ask for respect and privacy, for speculation to be tempered with compassion and humanity, and for our parents to be remembered for the incredible lives they lived and the love they gave," they added.
