Retired Birmingham homicide detective Chris Anderson and defense attorney Fatima Silva give us a behind the scenes look into their investigation of the Coleman Johnson case.  His ex-girlfriend was killed when she picked up a homemade bomb left on her front porch.  After a three-year investigation, Johnson was charged and convicted of first-degree murder.  But now, Johnson’s wife and daughter say the feds got the wrong man and they’re asking Chris and Fatima to join their fight for justice.
