A probable cause affidavit filed in the case has been sealed. In court documents, prosecutors said the release of  any information contained in the affidavit could compromise the ongoing law enforcement investigation.Huggins, police confirmed on Thursday, was once affiliated with the outlaw motorcycle gang, the Gypsy Jokers, and that his death is directly linked to that affiliation.

“Detectives can also confirm that the five people arraigned [Thursday] are in some way associated to each other through outlaw motorcycle gangs,” Sgt. Pete Simpson said in a prepared press release.

Prosecutors say Huggins was killed around June 30, 2015, though the specific location and cause of his death has not been released.

Dencklau, Fisher and Pribbernow “knowingly and intentionally” kidnapped and “did cause the death of [Huggins],” prosecutors said.

The three men are also accused of agreeing with each other, and potentially others, to “intentionally cause the death of [Huggins],” according to court documents. They are also accused taking Huggins to terrorize him..

Kendra Lee Castle and Ronald Charles Thompson are both accused of hindering prosecution. The specific role Castle and Thompson played in the case has not been released.
