They live in West Baltimore, which erupted in violence last year after Freddie Gray, a young black man, died in police custody. The local Catholic Charities started the auto tech training program in response to the unrest, to create more opportunity for people facing significant barriers to finding good jobs.Those barriers include “housing, mental health, substance abuse, alcohol, criminal backgrounds,” said program manager Anita Donaldson. “This program says, ‘Come here, and we're willing to help you get through that so that you can continue on your path to se...
