So that's what they mean by "killer" bread. On a more serious note, of the 12 ex-felons on their website, 2 are black males and 5 are women. This is highly nonrepresentative of prison demographics.
It seems likely that, for the same reasons normal companies prefer not to hire ex-felons at all, Dave's Killer Bread might prefer to hire ex-felons who are slanted toward the nonviolent end of the ex-felon pool.
You should read the story about the founder. It is an amazing company, and product! I wish more companies would give some felons a second chance. Not everybody is "bread" (hah!) to be a felon. Not everybody is hopeless, but as a society we sure stack the deck against them by denying them decent employment after they've paid their debt to society. Companies like DKB are much needed. They've changed a lot of lives for the better, and I'm sure have kept more than a few criminals from returning to their former "profession" by giving them skills and paying a living wage. http://www.daveskillerbread.com/our-history/#our-history-1
