Tanya Brown — whose sister, Nicole Brown, was slain in 1994 — opened up to TMZ about the eerie similarities between Rob and Michele Reiner‘s killings and the brutal murder of her sister, which sparked the infamous O.J. Simpson murder trial.

Tanya tells TMZ … she saw the words “murder in Brentwood” posted on social media Sunday night, which understandably conjured up old, terrible memories.

As we reported … Rob and his wife were found Sunday with their throats slit inside their Brentwood, California home.

Tanya said, “The story is very triggering — beyond triggering. I’ve shed a lot of tears … it’s very personal to me.”

While no one was ever criminally convicted in Nicole and Ron’s murders, Tanya says she hopes the Reiner family gets justice and “the person responsible doesn’t get away with it.”

“But I hope the person also gets rehabilitated while incarcerated,” she said. “It makes me sad for the family, I feel for them. This didn’t need to happen.”

Rob Reiner and his wife Michele’s deaths have sent shockwaves through Hollywood … and Donnell Rawlings is opening up to TMZ about the tremendous impact Rob had on the entertainment industry, and how profound the loss of the couple is.

Catch the full clip — Donnell looks back on Rob’s groundbreaking career, talking about how he embraced change when others wouldn’t and used his platform to open doors for people along the way.

Police in Rhode Island just released new surveillance footage of a person of interest in Saturday’s mass shooting at Brown University.

The video shows a person, dressed in all black, walking down Waterman Street near the corner of Hope Street … a couple blocks away from the Ivy League campus.

Rhode Island Attorney General Peter Neronha says investigators believe the person in the video is the same as the person seen in different surveillance footage … according to CNN. The person is still unidentified.

The Providence Police Department announced, “We are sharing a video of a person of interest and plan to release additional video as part of the ongoing investigation.”

A person of interest was taken into police custody Sunday, but has since been released after an investigation cleared him.
