Two former state correctional officers are going to federal prison for conspiring in the severe beating of an inmate at Roxbury Correctional Institution near Hagerstown in 2008.

Forty-one-year-old Lanny Harris and 42-year-old Philip Mayo were both sentenced Monday in Baltimore to 2 /2 years. They are the first among 15 federally convicted officers to be sentenced in the case.

Both pleaded guilty.

Harris, a former sergeant, approved a plan for other officers to assault Davis as punishment for punching a guard. He then helped organize a cover-up of the incident.

Mayo held Davis down while others kicked and punched him. He shielded Davis' face, at least partly to prevent obvious injuries.

Davis suffered a broken nose, back and ribs from being beaten by officers on three successive shifts.
