Rob and Michele Reiner's cause of death revealed

According to the Los Angeles County Medical Examiner, both Rob and Michele died from "multiple sharp force injuries." The manner of death for both was ruled a homicide. 

The medical examiner's report comes three days after the couple was found dead in their Los Angeles home.

Charges filed against Nick Reiner

What we know:

Nick Reiner was expected to enter a plea in a downtown LA courtroom on Wednesday, which marked his first court appearance since being charged in the stabbing death of his parents. 

During his appearance, he waived the right to a speedy arraignment and his official arraignment was postponed because the defense is still gathering information, officials said. His face was not allowed to be shown during the hearing. 

FOX 11's Christina Gonzalez was inside the courtroom and described him as being "disheveled." Nick Reiner, who was on suicide watch Tuesday, was wearing a suicide jumpsuit. She also said he spoke very softly. 

This comes the day after the Los Angeles County District Attorney’s Office announced the 32-year-old was charged with two counts of first-degree murder. 

Along with the murder charges, prosecutors added special circumstances of multiple murders and a special allegation that the defendant used a dangerous weapon, a knife. The additions could mean a greater sentence.

LA County DA Nathan Hochman has not made a decision on whether to pursue the death penalty. 

Prosecutors have called this case "one of the most difficult" when the victims and suspect are members of the same family.

There may be some kind of mental health episode occurring, either where he is refusing to get on the boss or he needs to be seen by a psychiatrist," explained Lauren Johnson-Norris, an attorney who is not in the Reiner case.

Rob Reiner, wife found dead in Los Angeles home

Actor Rob Reiner and his wife were found dead Sunday afternoon inside their Los Angeles home.

The backstory:

The 32-year-old, who was living with his parents, was arrested on suspicion of murder after his parents were killed at their Brentwood home over the weekend. 

The couple, 78-year-old Rob Reiner and 68-year-old Michele Singer Reiner, were found dead Sunday afternoon by their daughter, Romy. Investigators said Nick was not at the home when officers arrived, and detectives believe he left sometime after the attacks. 

He was then located and arrested in LA’s Exposition Park area, near the University of Southern California, on Sunday evening. His arrest took place about 14 miles from the crime scene. 

Photos of the arrest were released by LAPD's Gang and Narcotics Division. 

New details emerge

The night before the killings, sources reported that Nick got into a heated argument with his father at Conan O'Brien's holiday party. A witness told FOX 11 the couple's son had been acting "oddly" that night. 

Hours later, Nick Reiner reportedly checked into a Santa Monica hotel around 4 a.m., with hotel staff alleging they found blood in his shower and on his mattress.
