Walter Cantrell is a major and commander of the Southern District in Baltimore City.


Season 1

In 2002, Cantrell was a lieutenant in the Narcotics Unit and supervsied detectives Roland "Prez" Pryzbylewski and Leander Sydnor. Lieutenant Cedric Daniels, desperate to secure capable officers for the Barksdale detail, negotiated with Cantrell to detail the competent Sydnor in exchanged for also taking the erratic Pryzbylewski. ("The Detail")

Cantrell and Daniels were both candidates for the next major posting; however, Daniels's insubordination while conducting the Barksdale investigation led to his demotion to the Evidence Control Unit. Cantrell was thus promoted to major and became the commander of the Northwestern District in 2002. ("Sentencing")

Season 4

In 2006, Cantrell was now commander of the Southern District and prepared newly elected Mayor Tommy Carcetti for a ride along. ("Unto Others")
