A federal judge in Alexandria yesterday sentenced Donald D. Haynie, 34, of Nashville to 15 years in prison for his role as the leader of a major international drug ring.

U.S. District Court Judge Albert V. Bryan Jr. also imposed lesser sentences on four other members of the ring, which was broken by federal drug agents in December 1977 in a raid at Dulles International Airport.

All five were convicted last month after a nine-day trial in Alexandria during which details of the far-flung drug operation including dealings in India and Nepal were disclosed. The convictions have been appealed.

The charges against Haynie that led to yesterday's sentence included conspiring to import Asian hasish and possessing both hashish and marijuana with intent to distribute it.

Sentenced with Haynie were Jean A. Morrissette of Gainesville, Fla., and Michael Vlcek of Chicago, both of whom received three years in prison; Paul Max Jenkins of Fort Lauderdale, Fla., 18 months, and Lynn B. Fletcher, also of Fort Lauderdale, two years with 18 months suspended.

All defendants except Haynie are free on bail pending appeals.

Haynie was arrested by U.S. drug agents shortly after his conviction when he left Nashville for Atlanta in alleged violation of the terms of his $200,000 bond. Bryan scheduled a hearing for Tuesday on revocation of the bond.

Bryan also upbraided prominent New York attorney Gerald Lefcourt, and demanded that Lefcourt explain why he had "affronted" the court by an "11th-hour withdrawal" from defending Fletcher in last month's trial. Lefcourt said a conflict in trial dates had forced him to relinquish the defense to Alexandria attorney Gerald Lee.
