Best Friends Who Found Out They’re Sisters Learn They Have a Brother (Exclusive) [Video]

About a decade ago, Cassandra Madison posted on social media because she really thought she and two of her friends might be related.

DNA testing confirmed Madison, who had long been looking for more of her biological family, was right.

First, in 2021, she learned that Julia Tinetti, whom she had met in 2013 while working at a Connecticut restaurant, was her biological sister.

And then, this summer, another DNA test confirmed they have a biological brother, too: Madison’s childhood friend Thomas Buonaguirio.

“As soon as I saw him [Buonaguirio], I was like, ‘Oh my God, that’s me with a beard,’ ” says Tinetti, 34, who now works with individuals who have brain injuries and spinal cord injuries.

“This has been so crazy,” Tinetti tells PEOPLE. “This whole story has been wild. I didn’t think it could get any crazier.”
