Who Killed...? is a cold-case podcast hosted by Bill Huffman and credited on air as a Slow Burn Media and Evergreen Podcast production. It returns to old deaths and disappearances: what happened, what evidence was left and how investigators worked the case. Amy Mihaljevic is the clearest example. She was ten when she was abducted from the Bay Village Shopping Plaza in Bay Village, Ohio, on October 27, 1989. A recap in the series lays out the con that brought her there: a phone call that made her believe the caller was a family friend, and her wish to buy her mother a surprise gift for a job promotion. For Huffman, the case is close to home. He says he was ten himself, living in the city that borders Bay, and he describes joining the Walk for Amy held in her honor. Four episodes led up to the 30-year mark of her disappearance, each billed as a 30-year rewind, with parts two through four opening on a 'Previously on' recap. The conversations are specific. One takes on the composite drawings, explaining that they came from children who glanced at Amy talking with a man and had no reason to study his face. The sketches, in that account, give a general description rather than a likeness. Another covers physical evidence, including a curtain and a blanket recovered in the same area, and the practice of keeping such items for retesting as DNA science improves. Elsewhere, an interviewee explains that a missing-child search works outward in concentric circles from the family, however uncomfortable that is for a family already grieving. The hardest question is asked plainly. Amy, in words relayed from Mr. Mihaljevic, was very shy and would not have gone with someone she did not know, so how did the adult know her? The theories raised include someone doing work around the house, a teacher or a coach. The conversation also points out how bold it was to set up a meeting at a public shopping plaza across from a police station. It adds that a search for similar methods turned up only one close case from the 1980s, in Toronto. Each Amy episode closes the same way: contact details for investigators, the FBI reward for information leading to an arrest and conviction, and a reminder to be safe. The feed also goes beyond Bay Village. 'Evelyn Colon 1976' recounts a boy finding suitcases near a support of an interstate bridge over the Lehigh River, and follows the remains to a 1983 burial in the county's potter's field. 'Judy Martins with Nic from True Crime Garage' looks back at a case from 1978 and traces an on-again, off-again relationship from high school into college. Those episodes end with a request for reviews to keep the cases in the spotlight and a slightly different farewell: be healthy and stay safe.
