==Biography==
===Pre-Series===
Nothing is known of Walsh's life before his subordinate's death.
===NCIS Season 5===
In October 2007, Lieutenant Michael Arnett was assassinated during a failed suicide attempt. Due to the sensitive nature of the information handled by his subordinate, Walsh temporarily shuttered his department while NCIS conducted their investigation. Almost immediately the impatient captain badgered them for results, going so far as to wryly remark on the lack of progress to Director Shepard herself.
Agents Gibbs and McGee were granted brief access to Arnett's desk under Walsh's watchful eye; the former agent and the captain discussed the deceased briefly while each gauged the other. They discussed Arnett's private life, including his wife, from whom he had recently separated; the captain was unaware of this development, though he remarked that the lieutenant was quieter than usual in the days before his suicide attempt.
Walsh eventually relented on stonewalling the investigators and sent them Arnett's file, though it was redacted to the point of uselessness. Due in part to the captain's obstinant behavior, as well as the presence of an unidentified mole in his section, Walsh was briefly regarded as a potential suspect in the death of Arnett and the identity of the mole, though this was ultimately disproven.
Arnett's ex-wife, who in reality was a deepcover al-Qaeda operative, had shot her former spouse to ensure his silence and her cover. She was ultimately captured by NCIS agents, however, and Walsh's unit was able to resume their duties.
