Two Davenport men have pleaded not guilty in the stabbing and beating death of 29-year-old Romane Nunn Sr.

William E. Crawford, 42, and Durell R. Parks Jr., 34, waived their right to a formal arraignment Thursday and filed their pleas through their attorneys in Scott County District Court.

Both are charged with first-degree murder, a Class A felony punishable by life without parole, and willful injury resulting in serious injury, a Class C felony punishable by up to 10 years in prison.

They will be back in court Oct. 21 for a pretrial conference.

A third man, Terrell G. Bloch, 45, of Davenport, also is charged in Nunn’s death. He will be arraigned Oct. 20.

Davenport police were called to LeClaire Park at 8:21 p.m. Aug. 18 in response to a stabbing that occurred as scores of people were in the park playing the popular mobile app Pokemon Go.

According to police, the three men approached Nunn in the park and beat and stabbed him.

More than one witness told police that Crawford had a knife in his hand and that Nunn was stabbed in the chest, according to preliminary hearing testimony Aug. 30 from Davenport Police Sgt. Shawn Roth, supervisor of the department's major case unit.

Nunn was taken to Genesis Medical Center-East Rusholme Street, Davenport, where he died. Preliminary autopsy results revealed that he died from a wound to his main heart artery, Roth testified.

Crawford and Parks had blood on their shoes when taken into custody, according to court documents. Both were booked into the Scott County Jail the next morning.

Bloch was arrested Sept. 14. According to court documents, Bloch told police that he punched Nunn twice before fleeing the scene.
