At about that time, Brian Valdivia joined in.
"He was already like this on the side of the bridge," said Valdivia. "And I came over and I just bear-hugged him and then pulled him over, pulled all my weight towards me. Because if I were to fiddle with him over the bridge, then it was just going to be both us."
"He was right over these two lanes," said McPherson. "Just if he would have let go, he would have fallen over the freeway."
They held him until police could arrive.
"I helped the officer put handcuffs on him," said Valdivia. "And I just laid on my back like just so much was on me. I felt so much. This was life or death."
McPherson wanted a photograph of all of five men as a keepsake, but Bothell police tweeted it as a way of saying thanks.
The men all felt the weight of what they managed to prevent.
"He kept on saying, 'Nobody cares about me,'" said Valdivia. "I was like, 'If nobody cared about you, we wouldn't be here right now.'"
"It's been kind of hard on me today," McPherson said. "I'm trying to work. But I feel badly for this guy. I hope he gets the help that he needs."
Both men say they cried when it was all over.
Valdivia says he learned his lifesaving skills as a high school wrestler.
