Osby estimates he has investigated between 20 and 30 murders during his career. Since last year at this time, when he began working in a newly formed homicide unit established by Circuit Attorney Dee Joyce-Hayes, Osby has been involved in three more cases. “You do a whole of paperwork,” he says. It begins when the circuit attorney’s office or a grand jury issues an indictment. “You wind up getting medical records, autopsy reports, gun reports, evidence technician unit’s reports, photos — and that’s just the beginning.”
