David Sinclair

FBI Special Agent

Played by: Alimi Ballard


Full Name: David Sinclair

Venice, California

Birthdate: Unknown


Early Life:
David grows up in New York and goes to high school in the Bronx; he mentions having to avoid gangs and other obstacles in order to graduate. He tells Colby kids are shot at his school but it is usually over something, stupid things certainly, but not just randomly. His two best friends growing up are Ben Ellis and Earl Day.

He has at least one sister named Linda. His father dies when he is roughly fifteen.  He states he grew up in a loving home where his family was there to support him.  He has an autistic uncle who is the younger brother of his mother.

David went to Cornell University in Ithaca, New York and admits spending most of his sophomore year playing video games such as Missile Command and Frogger.

FBI Career
David’s first assignment after graduation from the FBI Academy is in Tel Aviv, Israel.  While there he learns about diffusing bombs.

He is assigned to Don’s team in 2005 by the Assistant Director of the LA office and has done some work with the Long Beach FBI office. He is usually in the field with Colby Granger; he has a difficult time reconciling their working relationship after Colby is exposed as a counter intelligence operative out to expose a leak in the Department of Justice.  Because he’s trying to work out his feelings, David starts taking more risks on cases, something that is earning him the reputation as being a cowboy.

In early 2009 David applies and is promoted to Don’s relief supervisor with Don’s blessing. After Don is stabbed during a case, David gets his first taste of being in charge of the team. In late 2009, David starts to think about his future with the FBI and asks Don what management positions might be open.

In early 2010, David is offered a team lead role for an anti-corruption team in Washington DC.  Don recommends him for the position.

Personal Life
David has not talked about his personal life or dating.  He does not like Linda going back to her ex-husband as David feels she can do better.

He is currently living in Venice, California.  As of early 2006, David is volunteering at the 23rd Street Community Center. David is still at the community center in late 2009, he is also involved with Big Brothers/Big Sisters.

As a result of “getting a lot of murder cases” David spends a lot of professional time with Claudia Gomez at the coroner’s office.  Colby suspects there may be a crush.

Hobbies Likes/Dislikes:
David does not drink coffee. He is an avid comic book collector starting his first collection when he is nine years old. David listens to Curtis Mayfield, James Brown and early Stevie Wonder music.

David has made a study of the Kennedy assassination and thinks there was more than one gunman involved.
