The heartbroken daughter of New York grandmother Alisa Goods has revealed what the surveillance video that captured her final moments showed — before she was later found dead in an embankment.

Goods, 63, plunged down an embankment near Las Vegas’ Harry Reid International Airport on Aug. 8 – and wasn’t found until 12 days later when her body was spotted by a homeless man.

Now, her daughter, Kristen Goods, has documented the mom of five’s final moments after viewing footage moments before the fall.

“She kind of looked like she had a heat exhaustion look to her and that she sat down and she then threw her bag that she was carrying over that embankment and proceeded to take herself over the embankment,” she told the NBC affiliate KSNV Monday.

“We were a little bit taken aback by that.”

Video showed Goods “falling down an embankment, getting back up and then collapsing,” Las Vegas cops said, after she left a longtime pal’s apartment to run an errand.

But Kristen Goods said it was out of character for the mom to walk alone in the heat as she continues to demand answers about the circumstances that led up to her mom’s death.

Goods’ cause of death hasn’t been released, but her daughter said she was found with a fanny pack.
