Following the Lincoln scandal, Dochow was demoted and placed into a relatively obscure office, but later, inexplicably was brought back into the Office of Thrift Supervision.
Dochow declined to answer questions from ABC News.
After Ronnie Lopez was killed in Iraq, his mother Elaine invested the life insurance proceeds at IndyMac. She lost $37,000 of it.
"I was hysterical," she told ABC News. "I literally thought I was going to kill myself that day, because I felt so bad that I had let him down. I remember going to his grave and telling him "don't worry, I'm going to get that money back', and I feel like he was saying 'hey mom, don't let them take that. I did the ultimate for that'."
A group of angry investors has started a website, demanding answers on the extent of Dochow's actions.
"It's just the strife and anger," said IndyMac customer Lisa Marshall. "That this Dochow person is still employed, it's unbelievable, it's shocking."
While Dochow could end up losing his job, neither he nor his colleagues are expected to go to prison.
"This is criminal with the small 'c'," said Black. "No one within the regulatory ranks may go to jail, but they have done the worst possible disservice to the taxpayers of America."
