A controversy over a pair of ex-police officers with suspected ties to the Ku Klux Klan took a new turn.

Prosecutors in Lake County have now dropped three cases involving those officers.

And those officers said their affiliation with the Klan was all part of an undercover investigation.

The Supervisor for the State Attorney’s Office said his decision to drop these cases isn’t because he’s found any evidence the officers were motivated by racism, but fears a jury would question their credibility.

The State Attorney plans to go forward with cases against nine individuals all arrested by Deputy Chief David Borst or Officer George Hunnewell.

Borst resigned from the Fruitland Park Police Department last week, and Hunnewell was fired after an FBI source said both were part of the Ku Klux Klan.

“Ones in which they caused a stop to be made or a search to be made especially against an African-American, I think it’s incredibly significant,” said News 13 legal analyst Mark NeJame.

The state attorney said he won’t put the officers on the stand but said in those cases he’ll prosecute, the evidence should speak for itself. Three cases were dropped where the officers were essential witnesses.

“To have it dropped not from a technicality in the court system but actions that were uncalled for is very aggravating to me,” said Chief Terry Isaacs with Fruitland Park Police.

We are also learning more about the claims of a third former member of the Fruitland Park Police, their former secretary and Hunnewell’s ex-wife that their involvement back in 2009 was part of an undercover investigation into the KKK.

Chief Isaacs provided News 13 a copy of a recorded interview with the police chief at the time, who flatly denied it.

“At no time did I ever instruct or have anybody working undercover infiltrating a Klan’s organization while I was the chief of police,” said former Fruitland Park Police Chief Mark Isom.

In a sworn statement then Chief Isom said he questioned his entire department back in 2009, and they all denied involvement with the Klan.

Current Chief Isaacs said he asked all his officers the same question this week, and is confident they aren’t part of the organization, which though not illegal is against department policy.
