"You have this perfect storm of several things that happened to her in succession," he said. "His suicide, her kids being taken away from her, the feeling that the media was out to get her, because they were putting out these reports that she was under suspicion in his murder."
McCready's last day was focused on getting the world to hear a song, he said. "I'll See You Yesterday" was the last thing she recorded with Wilson, who was a music producer. "It's such a beautiful song. It must be heard," she told NBC.
"I was your sunlight, but now I'm just a shade
"I was your blue sky, now I'm just the rain
"I was your favorite song, but now I'm overplayed
"If tomorrow's gonna be the same, I'll see you yesterday."
McCready asked Hanks to help her get it played on the radio. She also asked him to upload it to YouTube along with photos of her and Wilson.
"She was anxious to get this video posted," he said. "I didn't realize it at the time, I didn't realize what the urgency (was about)."
She told him she wanted it to be a suicide prevention public service announcement, he said.
"In retrospect, I realize what she was not revealing was that her true reason was that this was her suicide video," he said. "She wanted it out there because she knew that the video would get more play after she committed her suicide. She wanted the world at the end to know how she had been treated and mistreated and all the stuff that she had gone through."
Her last wish came true. The video has gone viral, getting hundreds of thousands of views since her death. Country radio stations are playing her song.
"If these people had reached out to her in life as they have in death, maybe it would be a different outcome," Hanks said. "If she had known how many fans that she had out there and how many supporters she truly did have, she might have had the courage to go on. But I think she just felt she was alone, that nobody cared about what was happening to her."
In the NBC interview aired on the "Today" show last month, McCready summed it up: "My life hasn't ever really made sense to me, because I do know what kind of person I am and I do know that I try to be as good a person as I can possibly be every day."
