Celeste Rivas went home to visit family in Lake Elsinore, CA exactly one year before her body was found in D4vd 's Tesla ... that's what this new video of her arguing with her parents' neighbors seems to show.

The video, obtained by TMZ, was recorded by a Nest camera on September 8, 2024 -- months after Celeste had been reported missing -- and neighbors say it shows her going off on a family over a prank.

In the clip, a family sits outside their apartment building, listening to music when Celeste starts yelling ... accusing one of the kids of ding-dong-ditching her parents' home.

While the nighttime vid isn't super clear, we're told the neighbors recognized the girl as Celeste because they'd seen her face on missing posters that had gone up in the area back in April 2024.
