Reporter: Next to shanann, that’s her husband Chris, a field coordinator at a local oil company. Shanann loves sharing their love story. Which started, not surprisingly, on Facebook. I got a friend request from Chris on Facebook. One thing led to another, and he is the best thing that has ever happened to me. And because of my health challenges, because I got so sick, I let him in. Reporter: Shanann suffers from the debilitating disease lupus. You just don’t sleep very good with lupus. She had her head on his lap, and they were watching TV. He didn’t move. He let her sleep for four hours. I told her, “God must’ve sent him to you.” Reporter: What did you all think of him? Loved him. Reporter: Less than two years later, shanann and Chris are married. He was so in love with her. Oh, my god. He did everything he could for her to make her happy. Reporter: The couple has two little girls, 4-year-old Bella and 3-year-old Celeste, also known as cece. Say hi, cece. Hi, daddy. Be careful, it’s hot. This is so good. The fire, the cookies. A lot of snow. Reporter: How was Chris as a father as far as you could see? He was a very loving father. As far as I knew, he loved his family. Reporter: Addy, who asked that we not use her last name, looks up to her friend, shanann. I just felt like she did everything the right way with so much patience. She was an amazing mom. She’d do anything for her children. She wanted them to have everything growing up. There’s nothing she wouldn’t do for those children. Reporter: And then, last June, another baby is on the way. I have a doctor appointment in two hours. I know, boy, boy, Chris wants a boy. I hope it’s a boy for him. It will make him happy. Reporter: As luck would have it, it’s a boy. She had a name for him already? Nico. She had to keep it Italian, you know? She was very proud to be part Italian. Reporter: Cristina Meacham and shanann Watts have been close friends for 14 years. I look at Bella, and I would look at shanann, and I was like, “You guys are exactly the same.” With cece, she was just, joy, complete joy. Reporter: The Watts’ home? Frederick, Colorado, a tight-knit Denver suburb with a family-friendly motto. “Built on what matters.” For shanann and Chris, family matters most. It was amazing just to see how they were as parents and as a couple. We’re going to organize the basement. They had a great marriage. What happens in space? Chris was a good dad. He could come home to work and take care of the girls. ??? My daddy is a hero ??? He helped them shower and get them ready for bed. Anything that he needed to. Can you tell I’m super happy, excited. She was hard-driven, a hard worker. She would work 12, 14 hours a day. Reporter: In 2016, shanann takes that strong work ethic to le-vel, a multilevel marketing company that sells vitamin infused patches. I’m very determined, and I am going to be extremely successful. Reporter: She excelled, winning an award from her company. Our team is just loaded with a lot of passion, a lot of heart and I love that we’re out there sharing the love with everybody. Reporter: Shanann was reaping the rewards of her hard work. Company trips to San Diego and New Orleans. Then in August, 2018, another company trip to Arizona. This time, Chris stays behind with the kids. But her friend and co-worker Nicole was with her on the flight home. Being that she was pregnant, on the way home, she was very uncomfortable on the plane. Reporter: And I believe it was around 1:45 in the morning that you dropped her off? Roughly, yeah. Reporter: What was the last thing you said to her? I just told her, “If you need help in the morning, let me know.” We gave each other a hug, and I watched her go in the house.
