Beauregard Donald 'Beau' Felton is a fictional character on the television drama series Homicide: Life on the Street portrayed by Daniel Baldwin for seasons 1-3.

When Beth leaves, Felton begins to drink heavily and his police work suffers as a result; Howard becomes disgusted with him following a binge in which he loses crucial evidence for a seemingly unsolvable case, assigned to her from the late Steve Crosetti's caseload.

Due to unsuccessful contract negotiations with actors Daniel Baldwin and Ned Beatty, Felton and Bolander were written out of the series after Season 3.

The narrative reason for the characters' absence is given in the Season 4 premiere, in which Giardello reveals that Felton and Bolander got drunk and engaged in embarrassing and grossly inappropriate behavior while attending a police/firefighter convention in New York City.

Julianna Cox soon determines that he had been murdered with a pistol shot to the back of the head; the killer then used the shotgun to stage the suicide.

[5] Giardello soon learns that Felton had actually returned from his long suspension to an offer to work undercover for Internal Investigations Division (IID), under the direction of Detective Stuart Gharty.

Felton had been undercover for six months helping IID and the FBI build a case against a massive auto theft ring, but an information leak led to his cover being blown.

A memorial for Felton is established in the police headquarters, and attended (on screen) by then-Maryland Governor Parris Glendening and then-Baltimore Mayor Kurt Schmoke.
