Little is known about the life of Matthew Miltenberger except that he was a professional scuba diver. He was found dead in the lobster tank of a franchise steak and lobster house under mysterious circumstances. According to the Narrator, Miltenberger was 37 years, six hours and 45 minutes old at the time of his death. It is likely that he was murdered, because a reward was offered for information surrounding his death, which private investigator Emerson Cod brought to the attention of Ned.
