Lester Poole was a gun technician with the Los Angeles Police Department's ballistics division.

He refuses to be called by the nickname Les, fearing that being known as "Les Poole" would eventually lead his coworkers to call him "cesspool."

In October of 1995, Poole ran the ballistics on bullets retrieved from the skull of Anthony Aliso and matched them to a gun found in the home of Luke Goshen.
