Early Life:
Colby is born and raised in Winchester, Idaho and attends a small high school with 200 students. His father died when he was fifteen and Colby is unsure if it truly was an accident or if his father committed suicide driving off a mountain road as a result of being fired from his machinist job. So far no mention of other family members. He is on the wrestling team in college.

After breaking his leg at the age of ten, Colby spends a summer watching Gary Cooper in High Noon.  The film is one inspiration for Colby to join the FBI later in life  Colby also enjoys watching Dragnet and this is his inspiration for wanting to join the police force.

Pre-FBI Career
Colby is in the Army’s Special Forces and serves in the Kunar Province of Afghanistan where he is injured at least once when his Humvee is blown up.  He holds a college degree and also has three years of interrogation technique training used with CID (Army Criminal Investigation) He serves in Afghanistan at the same time as Agent Edgerton though they do not meet. Colby participates in an operation in Afghanistan that results in the friendly fire deaths of two British agents; it is never clear who fires the shots that kill the men, and Colby realizes he will never really know if he is at fault.  He is fluent in Spanish.

FBI Career
Colby is a rookie in the FBI and is assigned to Don’s team in 2005, and the events in Judgment Call occur during Colby’s second week with the team.  He works most cases with David Sinclair or Megan Reeves. he holds the office record for combat pistol shooting.

In early 2007, Colby is arrested, along with his friend Dwanye Carter, on treason charges after it is revealed he is spying for the Chinese government. Unknown to anyone on the FBI team, Colby is working as a counter intelligence agent working to find a leak in the Department of Justice; he receives the FBI Medal of Meritorious Conduct for his efforts. It is assumed he will have his choice for whatever next assignment he wants with the successful conclusion of the DoJ investigation. he is offered a position with the Washington DC office, but turns it down, telling Don he would rather stay in LA if possible.  Don promises to see what can be done.

Personal Life
Colby moved to LA in 2005. He hasn’t dated anyone since moving to California partly because dating in LA is difficult, but working the undercover case doesn’t help. In late 2007 he starts looking more seriously even allowing Megan to set him up on a blind date.

By late 2008, Colby is still not seriously dating though he does have a one night stand with Lynn Potter, a material witness in a current investigation.
