A federal jury yesterday convicted Robert L. Stuckey, 41, of 2300 Good Hope Rd. SE, of 45 criminal charges in connection with his role in a major drug importation scheme here.

Stuckey had acknowledged in his trail here that he had participated as a drug courier in a ring he said was headed by convicted tax evader Linwood Gray. Stuckey said he participated in the organization only because he was afraid of Gray.

However, the jury yesterday convicted Stuckey on charges ranging from conducting a continuing criminal enterprise to submitting a fake application for a passport.

In a separate trial earlier this year, Gray was acquitted of running the drug organization, which, it had been charged, brought in more then $30 million of heroin from Europe. He was convicted of evading income taxes totaling several hundred thousand dollars over a two-year period.

Stuckey had been on trial with Gray at the time, but was given a separate trial when he told the judge he wanted to base his defense on Gray's alleged violence. Stuckey testified last week that Gray had been involved in at least three murders and the shooting of a federal prosecutor, but no charges have been filed against Gray in those incidents.
