A 38-year-old Washington man, who pleaded guilty to assault with a dangerous weapon in connection with a shooting outside Blacke's House of Beef in November 1977, was sentenced by a D.C. Superior Court judge yesterday to serve 11 to 35 years in prison.

In court papers, the government contended that the man, Sammie Jackson Jr., shot a Washington man in the stomach at close range after the man and his campanion twice refused Jackson's order to accompany him to a nearby parking lot.

The shooting occurred at 11:30 p.m., Nov. 11, 1977, outside the restaurant at 22nd and M streets NW. Jackson was arrested shortly after the incident by the highest ranking D.C. police official on duty that evening. The official had heard a radio report giving Jackson's description and then spoted Jackson gettting into a cab. At the time, police said, Jackson's last known address was 75 S St. NW.

In court papers submitted to Judge Joyce Hens Green, the city's Public Defender Service, which represented Jackson, said its client would have pleaded not guilty by reason of insanity if the case had gone to trial. Jackson had been drinking heavily and had used a hallucinogenic drug on the day of the incident and now cannot remember the circumstances of the shooting, the public defender said.

Jackson had served nine years in prison on robbery and assault charges and had been on parole for one month when the shooting occurred, according to court records.
