Detective Michael Scott Kellerman is a fictional character on the television drama series Homicide: Life on the Street portrayed by Reed Diamond. He is a main character from seasons 4–6 (1995–98). Biography Kellerman was born on July 20, 1966 in Baltimore to working class parents, the youngest of three sons. His father works at a distillery. He also has a sister who, by the time of the series, lived in St. Louis. He graduated from high school in 1984. He always wanted to be a cop and was a "good kid", quite different from his brothers Drew (Eric Stoltz) and Greg (Tate Donovan), who were always getting into trouble. Drew and Greg ended up drifting through much of the United States, occasionally turning up in Baltimore to ask for money. They appeared in the fifth season episode "Wu's On First?" on the run from two bookies, owing a gambling debt to one and having stolen a Babe Ruth uniform from the other. They were estranged from their father, who referred to them as "hoodlums". Kellerman had recently been divorced from a crime lab technician named Anne Kennedy prior to his joining the homicide unit. Kellerman would later confide with Meldrick Lewis that Anne had cheated on him. Kellerman worked his way up through the Baltimore Police Department, eventually landing in the Arson unit. When a pair of teenagers were killed in a series of warehouse fires, Kellerman was called in to help with the subsequent homicide investigation. With the squad short three men (Stanley Bolander and Beau Felton on suspension, Steve Crosetti dead by suicide), Lieutenant Al Giardello offered Kellerman a transfer to Homicide, having been impressed with his work on the cases. Although he initially refused the transfer, his father's statement that he works at the distillery because he's never done anything he wasn't already good at led him to accept the move to Homicide. Kellerman was partnered with Meldrick Lewis, with whom he would work during most of his time with the squad. Kellerman also crossed paths with Luther Mahoney and became determined to take down the drug kingpin after Mahoney arranged for the assassination of an intelligent, introspective, and tired-of-the-game drug dealer who had had a chance to kill Kellerman but chose to let him live.
