An O'ahu man faces a mandatory minimum prison term of 25 years without the possibility of parole after a federal jury returned guilty verdicts against Allan Aquino Lafuente on drug and firearm charges.

Lafuente, 39, was found guilty of one count of conspiring to distribute and to possess with intent to distribute 50 grams or more of methamphetamine; two counts of distributing 5 grams or more of methamphetamine; one count of possessing with intent to distribute 50 grams or more of methamphetamine; and one count of carrying a firearm in connection with a drug trafficking offense.

The offenses occurred in late 2005 and early 2006, said U.S. Attorney Ed Kubo.

Lafuente faces such a stiff term because he has a prior state felony drug conviction and because the amount of methamphetamine involved calls for a mandatory minimum sentence of at least 20 years, with a maximum penalty of life in prison, Kubo said.

Lafuente's firearms conviction also calls for a mandatory, consecutive prison sentence of five years.

He is scheduled to be sentenced before U.S. District Judge David Alan Ezra on July 27.
