D.C., police officer Tommy C. Musgrove, 26, has been sentenced by a D.C. Superior Court judge to a year in jail for beating a Silver Spring man in April 1978 while the man was in custoday at a police station on a disorderly conduct charge.

Musgrove, of 12603 Lampton Lane, Oxon Hill, was found guilty last spring of simple assault on Michael Morris 22, of 404 Hensdale Ct. Silver Spring.

According to testimony, Morris, a kitchen steward at the Mayflower Hotel, was arrested for disorderly conduct outside the Trailways bus station at 12th Street and New York Avenue NW and was taken to the 1st District substation cellblock in Southeast Washington.

Government witnesses asserted that Musgrove entered the cellblock and assaulted Morris with a blackjack after Morris had refused to give police his Social Security number and had spat on the officer.

Musgrove testified he struck Morris "to subdue him" after the spitting incident, but did not beat him with a blackjack, as Morris contended.

Musgrove was released on bond pending an appeal of his conviction by Judge Gladys Kessler, who sentenced him to the maximum allowable prison penalty for a simple assault conviction.

Morris did not file a complaint about the incident. But two other 1st District police officers -- Sgt. Earl K. Bell and Officer Benjamin Ash -- filed a brutality complaint in Morris' behalf after Musgrove had been exonerated by the police department.

Bell and Ash conducted an investigation of the incident, then presented their findings to the U.S. attorney. A Superior Court grand jury indicted Musgrove last November on one count of simple assault.
