Kerrigan says that Swasey, a police officer at the University of Colorado - Colorado Springs, was "like a brother" to her, and they even had nicknames for each other.
"I called him 'Ugh,' he called me 'Yuck,'" she says. "We were always teasing each other like a brother and sister."
"I could feel the energy and excitement of him rooting for me," she recalls of a time Swasey, 44, was cheering her on at a United States Figure Skating Championship. "It made me laugh. Instead of listening to music, I found that humor helped, it was good for me and it helped push me to do better."
"I always felt, for years and years, that he was definitely a big part of that," Kerrigan adds. "I am very thankful for having him in my life."
The late police officer was originally from Stoneham, Massachusetts, the same town outside Boston where Kerrigan grew up. He moved to Colorado in the '90s to further train as a champion ice dancer at the Olympic Training Center, later retiring from the sport there and moving into law enforcement.
"His dad picked me up at school every day to take me to the rink," Kerrigan reveals. "We were together an awful lot as children. I would ride my bike to his house and we’d hang out at the pool. We were together all the time, whether we were skating or not."
One thing Kerrigan will always remember of her late friend is his constant smile and heart of gold.
"I don't ever remember him ever being in a bad mood," she remembers. "He was always ready to listen, to be there, to help, to encourage somebody else. He was just a really good friend, very loyal and kind. He had a big, giant, smile all the time, even when we were teasing each other."
On Sunday, the names of the two other victims that were found dead were announced -- Ke'Arre Stewart, a 29-year-old Army veteran who served in Iraq and the father of two children, and Jennifer Markovsky, a 36-year-old married mother of two.
