DOVER, Del. — A former Dover Air Force Base airman has been sentenced to 10 years in federal prison after pleading guilty to sex trafficking of a child.

Dalian Washington received the minimum mandatory sentence Tuesday. He faced a potential life sentence.

Washington and another airman, Akeem Beazer, were arrested last April after a young teen told a social worker that she had stayed on the military base and had sex with service members. The teen had a troubled home life and often lived on the street.

In return for Washington’s guilty plea, prosecutors dropped charges of sex abuse of a minor and conspiracy to commit child sex trafficking.

Beazer was sentenced to 30 months in prison after pleading guilty to sexual abuse of a minor.
