Two District residents have been indicted in the 1982 killing of a gas station manager who, police later discovered, had hidden in his apartment the largest cache of pure heroin ever seized in the District.

The defendants, Michele A. Anderson, 29, and Randall K. Brown, 28, were arrested last week and charged with first-degree murder in connection with the death of Rasheed K. Zaman, whose body was found in his Northwest apartment with a bullet wound in the head early on the morning of June 25, 1982. Police discovered the large quantities of heroin in a briefcase and in a kitchen wall as they searched the small apartment.

At the time, police said the huge amount of heroin, about 90 percent pure, underscored the District's epidemic drug problem. The cache amounted to seven pounds of heroin worth an estimated $22.4 million.

Anderson and Brown were first arrested in connection with Zaman's death in 1982, a few days after the body was discovered. A third suspect also was arrested but charges against the three were dropped nine months later.

Prosecutors did not say yesterday what new information led to the indictment of Anderson and Brown. The third suspect, Bruce F. Wooten, 25, was indicted in February on a charge of first-degree murder and pleaded guilty in May to lesser charges of second-degree murder and second-degree burglary.

The indictments against Brown and Anderson, filed July 30, were sealed under court order until late last week because prosecutors feared the two would flee if word of the charges surfaced.

Anderson was extradited from New York to the District where she is expected to appear today in D.C. Superior Court, according to court officials. Brown is being held without bond in the D.C. Jail. Wooten currently is serving a prison sentence for a 1983 robbery conviction.

At the time of the 1982 arrests, police said the three apparently intended to rob Zaman of cash, because they overlooked much of the heroin hidden in his apartment.

After Brown was arrested in 1982, detectives found $4,522 in cash and approximately five ounces of heroin with a street value of about $350,000 in his apartment. Police believed the heroin, 97.7 percent pure, came from Zaman's supply.
