Police say the six-month drug sting that landed Harmon behind bars also led to the arrests of a dozen other people in Grant County.
Police say it's a drug operation ranging from cocaine to painkillers. Harmon was allegedly illegally selling prescription drugs near a Sheridan school. While there's no evidence linking him and the other 12 suspects, police say they are all part of an ongoing drug sting.
"Anybody who sells drugs is a threat to the public," said Assistant Police Chief Brent Cole.
Harmon, the former Saline County prosecutor, is back behind bars barely four years after serving time for extortion, racketeering and drug conspiracy from a 1997 conviction.
"If he thinks that he's going to be able to do it because of his status, that being a former prosecutor, then he's wrong. It's not going to happen here," said Cole.
Harmon is among the last few alleged drug dealers taken off Sheridan streets after a six-month drug investigation. Harmon lives in Saline County but the investigation led police to a traffic stop in Sheridan on Mockingbird Lane off Main Street.
Police say they found several drug items in his car. A passenger in the car a well-known drug dealer is also now helping authorities.
"Every time you're dealing with narcotics or this type of criminal element it can be dangerous and can get dangerous anytime," said Cole.
The assistant police chief says the former prosecutor is facing several felony charges that could land him prison and this time it could be for life.
"I think it is sad, you know, the man was prosecutor. He used to prosecute people for the same crime that he's committing," Cole said.
Police are not releasing any information or photos of the 12 other suspects but they also face serious charges. Cole says for a small community the size of Sheridan, he hopes the sting sends a message to offenders still out there.
"It doesn't matter who you are we are going to come after you," he said.
Even though police say Harmon was selling the drugs near a school they don't believe he sold them to any young kids. He is still in jail tonight on a $100,000 bond.
Harmon served one term as Saline County prosecutor in 1979. Voters elected him again in the nineties for two-terms. He resigned after his 1996 arrest. He got out of prison early in 2006 for helping prosecutors in a murder case.
