After losing her 7-month-old son Lukas in 2013, Heather Clark made a decision that would allow her baby boy to help other kids in need.
The devastated Arizona mom decided to donate Lukas' organs, and in the process saved the lives of three children.
One of those children is 4-year-old Jordan Drake. Clark had the opportunity to listen to her son's heart — beating in young Miss Drake's chest — for the first time in nearly three years.
In December 2015, Clark posted a message on the "Justice for Lukas Scot" Facebook page, a support page about the boy who allegedly died from injuries inflicted by a person babysitting him at the time. Clark let the page's followers know that she had connected with Drake and her family:
"I would like to share something with all the amazing Lukas supporters," Clark wrote. "Today I have been in contact with a beautiful family. This beauty is the girl who has Lukas heart beating in her. One day I will meet her and squeeze her so tightly! Thank you to her mom and dad who allow me to be a part of their lives. This is the best Christmas present I could have asked for."
That "one day" was on January 30, when Clark met Drake and her mother, Esther Gonzalez, at Phoenix Children's Hospital and listened to Lukas' heartbeat through tears.
"Thank you. Thank you," Gonzalez told Clark while hugging her. "That's your baby."
Jordan Drake was been born with a congenital heart defect, according to CNN, and needed a heart transplant in order to survive.
