A wedding day is one of the most special days of a person's life, but Becky's fiancé, Kelly Turney, wanted to make this day even more unforgettable for his bride.

Two years before their wedding, Becky lost her 19-year-old son, Triston. On her wedding day, she wanted him to be part of it in any way he could.

Becky set aside an empty chair with a sign that said, "I'm in Heaven for your wedding so what shall I do? I'll come down to Earth to spend it with you. So save me a seat just one empty chair, you may not see me but I will be there."

The surprise of Becky's life was about to unfold, thanks to her fiancé. He had spent months planning for a young man from San Diego to travel to Alaska on their wedding day. When Becky saw him, she couldn't hold back her tears.

Jacob Kilby, 21, was born with hypoplastic left heart syndrome and was operated on three different times at less than two years old When he suffered from a nearly fatal heart attack in 2015, he was put on the long heart transplant waiting list, and eventually received Triston's heart.

Kilby allowed Becky to listen to his heart through a stethoscope so she could hear her son's heartbeat again. Although her son wasn't present, she could still literally feel his heart beating.

"Everyone has a legacy, but to see how Triston changed Jacob's life is just incredible. It makes you super proud," Becky said.

Becky's son was able to save four other lives through organ donation, and Jacob hopes that this heartwarming story will inspire others to become organ donors, and for organ recipients to connect with the donor's families.

Instead of giving details on how Triston passed away, the family wants the focus elsewhere. "We want the focus to be on organ donation and the relationship and the healing that goes on between recipient families and donor families. That's our focus," Kelly said.

The family hopes to inspire others through their beautiful story. Although Triston is no longer on this earth, his legacy lives on.
