Authorities raided a number of homes in the Falls on Tuesday and apprehended three of four brothers they say ran a huge crack and cocaine business.
Randy, Robert and Steven Knighton of the falls were all arrested and face up to 20 years behind bars and a million dollar fine.
Another brother, Raymond Knighton, is still being sought.
Falls police and the DEA say they used operatives to purchase drugs from the brothers 10 times and they also stopped a shipment of two kilos of cocaine.
This isn't the first time the family has run into trouble -- just Raymond and Randy have been arrested 39 times.
