SACRAMENTO -- An East Bay man was sentenced Thursday to 10 years in prison for using his Alameda restaurant as a front to store and distribute thousands of pills of ecstasy.

David Chong, 38, was sentenced by United States District Judge Morrison C. England Jr. for his role in a scheme that ended with the ultimate seizure of 39,000 pills of ecstasy in 2008, authorities said.

Morrison also sentenced Robert Ly, 29, of Sacramento, to nine years in prison; Dassany "Daisy" Keohimanh, 30, of Stockton, to eight years and one month in prison; and Darryl Smith, 31, of Sacramento, to five years and 10 months in prison. All will serve time for conspiring to distribute ecstasy and for possession with intent to distribute the drugs.

Last December, a co-defendant, James Johnson, was sentenced to seven years and three months in prison. His age and city of residence were not released. Two other co-defendants, whose names were not released Thursday, are scheduled to be sentenced on May 30 for their roles in the drug trafficking scheme.

Between April and December of 2008, undercover federal agents purchased roughly 9,000 ecstasy pills, with an estimated street value of $315,000, from Johnson. On Dec, 8, 2008, the California Highway Patrol seized 11,000 ecstasy pills from a vehicle driven by Ly after he was stopped by police on Interstate 80 near West Sacramento.

When prosecuted in federal court, drug traffickers are not eligible for early release or parole.
