HONOLULU -- A marijuana drug organization on Maui is dismantled after a two-year investigation, law enforcement officials said.

Under "Operation Weedkiller" local law enforcement officials arrested and charged seven residents.

Operation Weedkiller Arrests:

Brian Igersheim, 31

Robert "Bobby" Armitage, 58

Douglas Kaleikini Sr., 54

John Cooper, 40

William "Bill" Cox, 48

Stuart Hirotsu, 48

Brian Murphy, 53

The men are accused of exploiting medical marijuana laws.

Murphy is the director of Patients Without Time, a strong advocate for medicinal marijuana laws. The men are accused of using the organization to disguise their marijuana drug trafficking operation.

Maui police charged Murphy and the other men with a number of offenses including drug trafficking. The men are suspected of abusing medical marijuana laws for personal profit.

In the bust, authorities recovered hundreds of marijuana plants and more than $14,000 in cash.

It was a joint investigation involving state and county task forces.

All of the men arrested have Maui addresses.

The seven men face possible indictments. The investigation is ongoing.
