LOS ANGELES (AP) — Rob Reiner’s son Nick Reiner was charged Tuesday with two counts of first-degree murder in the killing of his parents, which stunned their communities in Hollywood and Democratic politics, where both were widely beloved.

Nick Reiner, 32, is charged with killing the 78-year-old actor and director Rob Reiner and his wife, Michele Singer Reiner, District Attorney Nathan Hochman announced at a news conference with LA Police Chief Jim McDonnell.

“Their loss is beyond tragic and we will commit ourselves to bringing their murderer to justice,” Hochman said.

Along with the two counts of first degree murder, 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.

Hochman said his office has not yet decided whether to seek the death penalty in the case.

“This case is heartbreaking and deeply personal, not only for the Reiner family and their loved ones but for our entire city,” McDonnell said. “We will continue to support the Reiner family and ensure that every step forward is taken with care, dignity and resolve.”

The announcement came two days after the couple was found dead from apparent stab wounds in their home in the upscale Brentwood neighborhood on the west side of Los Angeles.
