A U.S. District Court jury yesterday convicted two men, including a disbarred lawyer, in what law enforcement authorities described as a major PCP manufacturing operation in Southeast Washington.

U.S. Attorney Joseph E. diGenova praised the verdict as having prevented PCP with a street value of $9 million "from finding its way into the brain tissue of a substantial number of District of Columbia residents."

The jury found George D. Gates, 48, a former D.C. lawyer who was disbarred after a 1979 heroin conviction in Texas, and Daniel L. Lampkins, 29, of the District each guilty on four counts of illegally manufacturing the drug.

Gates and Lampkins were arrested last year after an explosion rocked a Southeast apartment where authorities later found PCP ingredients and equipment.

Witnesses did not identify Gates and Lampkins as the two men who were seen fleeing the burning apartment through a window. Gates, however, underwent treatment at the Washington Hospital Center at the time for severe chemical burns, according to testimony.

Assistant U.S. Attorney William O'Malley argued that it was a "proper inference" that Gates had been present in the PCP laboratory. Lampkins signed the lease for the apartment, court records show.

U.S. District Judge Norma Holloway Johnson ordered both men held without bond pending sentencing. Gates is to be sentenced Feb. 14, Lampkins on Feb. 19. Both face a maximum of 70 years.
