A Bergen County Prosecutor's Office-led probe into heroin distribution  in Bergen and surrounding counties resulted in seven arrests in Fair  Lawn and two arrests of Fair Lawn residents outside of the borough....The multi-jurisdictional narcotics investigation, coordinated by the  Bergen County Prosecutor’s Office, nabbed approximately 120 individuals,  ranging from drug traffickers moving heroin between Trenton and  Paterson to suburban North Jersey buyers, Molinelli said.  The heroin probe was launched early this year in response to a more  than 100 percent increase in Bergen County overdose deaths from 2011 to  2012, including a dozen deaths over a four-month span beginning last  June.
  Authorities put eyes on Paterson after learning many of the Bergen County overdoses were linked to drug purchases made there.  
Fair Lawn Interim Police Chief Glen Cauwels  said that investigators used surveillance techniques to identify where  heroin sales were taking place in Paterson and who was making the sales.  
...Since multiple routes out of Paterson run through Fair Lawn, many of the  task force’s buyer arrests occurred in the borough. 
Seven alleged  buyers from as far out as Hewitt were arrested in Fair Lawn over the  four-month investigation.
Cauwels said buyers also frequently stop in Fair Lawn to use heroin after purchasing it in Paterson. 
  “That’s why you see a lot of drug arrests at the CVS. They’ll pull  over in the parking lot,” he said. “Officers will see a car parked away  from everybody else, they’ll see multiple people in the car and activity  in the car, so they’ll just roll up and see what’s going on and most  likely they’ll see the person actually doing the drugs in the car and  make the arrest.”
...Cauwels said he thinks the recent prosecutor’s office probe may help  dampen the county’s heroin problem temporarily, but that drugs always  seem to make a comeback.  “Drugs have been a problem for a long time and you never seem to  solve the problem,” he said. “For a while it was Ecstasy, now it’s  Molly, now it’s heroin. It seems like whenever one is going out there’s a  new one coming in.”
  Cauwels said the focus in Fair Lawn remains stopping any drug distribution that is occurring in town.
  “That’s our main concern,” he said.
