Lisa Garzone married John Joyce in 1994. They had four children together, and at one point, says Lisa, they were best friends. But their marriage ended badly.
"John became alcoholic, and things got volatile," she says, "so we had to have him leave."
John wound up living on the streets. "He stopped showing up for visits. I tried to follow where he was, and I knew that he was homeless — that just always worried me. I didn't want him to die on the streets."
