Bail hearings were scheduled for today for four of seven men charged last week on Maui with operating a drug-trafficking organization that allegedly exploited Hawai'i medical marijuana laws.

The two-year "Operation Weedkiller" task force investigation resulted in the arrests Nov. 11 of Brian Murphy, 53, of Pa'ia; Brian Igersheim, 31, of Makawao; William "Bill" Cox, 48, Ha'iku; Stuart Hirotsu, 48, of Wailuku; Robert "Bobby" Armitage, 58, of Wailuku; Douglas Kaleikini Sr., 54, of Wailuku; and John Cooper, 40, Kihei.

Authorities seized 335 marijuana plants and clones, 2,300 grams of processed marijuana, 4,830 grams of unprocessed marijuana, 32 grams of hashish, 100 marijuana-laced candies, a vehicle, $14,085 in cash and other items associated with marijuana growing and distribution.

Murphy, Igersheim, Hirotsu and Cox were scheduled for bail hearings today before Circuit Judge Joseph E. Cardoza.

The three other suspects are scheduled for arraignment Thursday in Cardoza's courtroom.
