MANDAN, N.D. — Four men believed to be motorcycle gang members face conspiracy to commit murder charges in connection to a stabbing at a July street dance in Mandan.

The Morton County State’s Attorney's Office filed the Class AA felony charges on Friday, Sept. 11, against Nash Wollan, 48, of Williston; Girard Lee Glaser, 49, of Bismarck; and Mandan residents Nicholas Kinsella-Greff, 28, and Edward John Nuckols, 32.

If convicted, the four could be sentenced up to life in prison without parole.

They also each face a Class C felony charge of committing a criminal street gang crime.

The charges stem from the nonfatal stabbing of a 33-year-old man during a July 3 street dance hosted by the Silver Dollar Bar in the 100 block of First Avenue Northeast. Court documents did not name the man who survived multiple stab wounds.

According to court documents:

The victim told the Mandan Police Department that several men walked up to his group. One of the men took the victim to the ground and put him in a chokehold. The victim said he was punched multiple times and discovered later he had been stabbed.

Police said the victim suffered eight stab wounds, including two to his head and three in his upper back.

Mandan police declined to identify the victim, deferring identification to the Morton County State’s Attorney's Office. The prosecuting office did not return a message left by Forum News Service by publication time.

Based on video and descriptions from witnesses and the victim, investigators identified Wollan, Nuckols, Glaser and Kinsella-Greff as suspects, court documents said.

Witnesses and the victim told police Wollan, Glaser and Nuckols are members or have an “aspirational affiliation” with the Sons of Silence Motorcycle Club, according to court documents. A criminal complaint said Kinsella-Greff had an unknown affiliation with a motorcycle club.

Investigators were told by an anonymous source that Sons of Silence members attacked members of the Hells Angels Motorcycle Club at the street dance, the complaint said.

The U.S. Department of Justice has dubbed the Hells Angels and Sons of Silence as "outlaw motorcycle gangs." The complaint said members of these gangs use their clubs as “conduits for criminal enterprise,” including violent crime and drug trafficking.

The Sons of Silence has claimed territory in North Dakota, Mandan police said. “Within the last two years, a motorcycle club in North Dakota ‘patched’ over to the (Hells Angels), a direct challenge to (the Sons of Silence) authority in the state,” the complaint said, noting that the two groups are historic rivals.

The four accused have not been booked into the Burleigh-Morton County Detention Center. A search of an online jail roster showed they were not in custody at other North Dakota jails as of Friday afternoon, Sept. 11, and court records did not list attorneys for the four.
