John Gibson was a pastor and seminary professor. When he wasn't teaching at New Orleans Baptist Theological Seminary, one of his favorite pastimes was fixing cars.
He was married with two children. His daughter, Callie, was teaching in front of 250 college students when she got the call. Her father had killed himself.
It was August 24, six days after hackers exposed the names of millions of people who had signed up for Ashley Madison, the notorious site for those seeking affairs. Gibson's name was on the list.
His wife, Christi, discovered her husband's body.
"It was a moment that life doesn't prepare you for," she told CNNMoney. "I had to call my kids. How do you tell your kids that their dad is gone and that he took his own life?"

In his suicide note, Gibson chronicled his demons. He also mentioned Ashley Madison.
"He talked about depression. He talked about having his name on there, and he said he was just very, very sorry," Christi said. "What we know about him is that he poured his life into other people, and he offered grace and mercy and forgiveness to everyone else, but somehow he couldn't extend that to himself."
Ashley Madison was hacked in July, and hackers released users' personal information in August. Since then, authorities in Toronto have said they're investigating suicides that could be linked to the data dump. Hackers have also sent extortion emails to people who were on the list.
Gibson said her husband was likely worried he'd lose his job.
"It wasn't so bad that we wouldn't have forgiven it, and so many people have said that to us, but for John, it carried such a shame," she said.
Gibson, 56, was known as a great teacher with a "quirky laugh," but he had struggled with depression and addiction in the past, his family said.
In a statement, a spokesman for Avid Life Media, Ashley Madison's parent company, expressed the firm's condolences.
"Dr. Gibson's passing is a stark, heart-wrenching reminder that the criminal hack against our company and our customers has had very real consequences for a great many innocent people."

Since his death, his family has made a pact to be more transparent with one another about their struggles.
Christi Gibson has a message for the 32 million people exposed and their communities.
"These were real people with real families, real pain and real loss," she says. But "don't underestimate the power of love. Nothing is worth the loss of a father and a husband and a friend. It just didn't merit it. It didn't merit it at all."
