Prosecutor Nathan Hochman announced formal murder charges against Nick Reiner and said the defendant faces life without release or the death penalty, following the killings of Rob Reiner and Michele Reiner earlier this week.Authorities say a knife was used; investigators arrested 32‑year‑old Nick Reiner shortly after a family member discovered the couple and he is being held without bail at Men’s Central Jail while prosecutors continue laboratory testing and witness interviews.Hochman said prosecutors are working around the clock with a decades‑experienced team, the family asked for privacy, and public speculation has not been substantiated by investigators.
