PORTLAND — Four men, all affiliated with an outlaw motorcycle gang, are facing murder charges in the death of a man whose body was found in Ridgefield last summer, police announced Wednesday.

Robert Lee Huggins’ body was found by loggers in an open field on July 1. Investigators said it appeared that the 56-year-old’s body was dumped there, about 100 feet south of 179th Street. Investigators learned of a suspect that same day, but it took detectives from the Clark County Sheriff’s Office and the Portland Police Bureau nearly 10 months to build a case against those believed involved.

Mark Dencklau, 56, of Woodburn, Ore.; Earl Fisher, 47, of Gresham, Ore.; Tiler Pribbernow, 34, of Portland; and Malichi Watkins, 32, of Camas are each expected to be arraigned Thursday afternoon on charges of murder, conspiracy to commit murder, first-degree kidnapping and conspiracy to commit kidnapping, according to police.

Dencklau and Fisher were arrested Wednesday. Pribbernow and Watkins already were behind bars for other reasons: Watkins is in Stafford Creek Corrections Center for failing to register as a sex offender, while Pribbernow is in a Portland jail for a suspected parole violation.

Police said that on Wednesday they also arrested gang affiliates Ron Thompson, 51, of Portland and Kendra Castle, 43, of Gresham on suspicion of hindering prosecutors in the case. Investigators said they might make additional arrests, too.
