Two young women were added Monday to the list of 20 victims killed in the upstate limo accident over the weekend.

Amanda Rivenburg, 29, of Albany and Rachael Cavosie, 30, of Waterford were celebrating their friend Amy Steenburg’s 30th birthday when the driver of their stretch 2001 Ford Excursion blew through a stop sign in Schoharie and crashed.

Rivenburg was a social worker at Living Resources, an organization for disabled New Yorkers. Her supervisor, Frank Prevrati, told The Times Union that she was the “heart” of the organization and a “young superstar.”

“She was dedicated and wonderful and kind,” he said.

Cavosie was also remembered for her kindness by her cousin Alyssa Cavosie.

Rachael was a “soul that touched so many lives,” Alyssa wrote in a Facebook tribute.

“She gave me so much guidance, and even though she was the younger cousin, I looked up to her and often sought her advice through out my life,” Alyssa wrote, noting that they were just three months apart in age.

Rachael’s father, Michael Cavoise, declined comment when he answered his daughter’s cellphone late Monday.
