Alfred Silva, 47, of Hilo has been charged with possession and attempted distribution of methamphetamine.

Silva was contacted by police for traffic violations while he was operating a Jeep Wrangler on Wednesday, Hawaii island police said. Police later obtained a vehicle search warrant and recovered over 320 grams of methamphetamine, more than 30 clean and unused Ziploc packets, a glass smoking pipe, and a scale.

Silva made his initial appearance in Hilo District Court this afternoon. His bail was maintained at $220,000 and he was ordered to appear for a preliminary on Monday.

Silva is charged with promoting a dangerous drug in the first degree (possess one ounce of methamphetamine or more), attempted promoting a dangerous drug in the first degree (attempt to distribute one-eighth ounce of methamphetamine or more), and promoting a dangerous drug in the third degree.

Promoting a dangerous drug in the first degree and attempted promoting a dangerous drug in the first degree are both Class A felony offenses which carry a penalty of either a 20-year prison term or 10 years probation and up to 24 months in jail.
