Scott Higham is a reporter on The Washington Post's investigative staff. Before joining the newspaper in 2000, he worked for the Baltimore Sun, the Miami Herald and the Allentown Morning Call, spending much of his 15-year career producing investigative projects. At the Miami Herald he worked on a year-long police corruption investigation and was a Pulitzer Prize finalist for a magazine article he co-authored with April Witt that explored the lives of seven teenagers who murdered one of their friends. He also served on a six-reporter team assigned to cover the aftermath of Hurricane Andrew and belonged to another team that was cited as a Pulitzer finalist for its reporting on a legal battle fought by parents of a child born without a brain.

At the Baltimore Sun, he worked with Walter F. Roche Jr. on a conflict-of-interest investigation that prompted the first expulsion of a state senator from the Maryland General Assembly in 200 years. He also led the Sun's coverage of the Oklahoma City bombing and conducted investigations of the Maryland State Police, the Housing Authority of Baltimore and the Maryland Circuit Court system, each of them resulting in numerous government reforms.
