In the federal indictments, a majority of those who testified against the officers are previously convicted felons and Gray and McFadden.
The investigation has caused eleven people to be released from state or federal prison or their charges have been dropped.
Gun carrying drug dealers, thieves, child kidnappers, these are just a few of the crimes that landed 20 felons in state prison alone.
Other than officers or other unnamed sources at least 25 people were named in the indictments.
That is before they testified against six Tulsa Police officers now accused of corruption.
Officer Jeff Henderson faces 58 counts, Bill Yelton faces seven charges, Nick DeBruin faces six counts, Bruce Bonham faces five counts, Harold Wells faces ten counts.
All but Wells have pleaded not guilty. Wells has not been given the opportunity to plead.
Retired officers JJ Gray pleaded guilty to one count and ATF Agent Brandon McFadden pleaded guilty to four counts.
"Whether someone is guilty of the offense or not they deserve their constitutional protections that are there for everyone," says Jane Duke, U.S Attorney in the Eastern District of Arkansas.
The officer’s attorneys say they’ll fight this till the very end.
"The federal government has had it in for officer Henderson for quite some time and we sense that from the witnesses that we found out from the government that are not as savory as they put them off to be," says Henderson’s attorney, Chad Greer.
Yelton is also charged with illegal search and seizures and conspiracy to commit witness tampering.
"Obviously he has made some people mad and they have found a way to get back at him," says Yelton’s attorney, Anthony Allen. "They have found a miracle situation where the government will believe criminals conspiracy to say that Bill Yelton has done something wrong and he has done nothing but fight for his county for his whole career."
DeBruin who faces charges of stealing money for personal benefit has pleaded not guilty.
"They are in a very unique position of utilizing criminals to come in and released themselves," says Shannon McMurray, DeBruin’s attorney.
None of the officers have been convicted but eleven people have been released from state or federal prison or charges have been dropped.
Assistant District Attorney Steve Kunzweiler says they are reviewing three more cases that involve some of the officers indicted.
Duke says unnamed officers and other law enforcement have also testified in front of the grand jury that put six officers and a federal agent under indictment.
"The grand jury has heard from a number of witnesses and they are not all criminals and to the extent that we have been able to substantiate the allegations of these individuals we've done that and we feel there is some measure of credibility that these individuals are saying,” says Duke.
It’s the chief’s call to decide if the officers get paid or not while on leave. The Chief says these officers have not been convicted and have pleaded not guilty.
TPD’s Internal Affairs Captain says there are different due process rules between federal and state cases.
Since this is a federal case he says the officers are allowed to be paid while on leave, however, as more information is released their status can change.
Wells has not been given the opportunity to plea.
The remaining officers with the exception of Gray and McFadden have pleaded not guilty.
Henderson and Yelton have been arrested and jailed and are scheduled to be in federal court on Friday.
