Police think they have the suspect who killed a 19-year-old Davenport man outside the Col Ballroom behind bars at the Scott County Jail.

Robert Steffon Darnel Williams, 21, of 1815 W. 40th St., Davenport, was booked into the jail Tuesday afternoon, charged with first-degree murder. Two others already have been convicted of lesser charges related to the shooting.

“He’s the last one we’re ready to go to court on,” Davenport Assistant Police Chief Don Schaeffer said.

Williams was wanted on first-degree murder and other charges connected to the shooting last year when he was taken into custody in Chicago on an unrelated weapons charge earlier this year.

His initial appearance was Wednesday morning in Scott County District Court, Davenport.

Davenport police responded to a shots-fired call at

11:28 p.m. May 7, 2011, at the Col Ballroom, 1012 W. 4th St.

A fight had broken out minutes before inside the building, where platinum-selling rapper Trina was performing. When officers arrived, they found a group of people outside the building on 4th Street.

Michael Elijah Gabriel Williams, 19, of Davenport, was found lying in the street near the parking lot a block east of the club. He was taken to Genesis Medical Center, East Rusholme Street, where he was pronounced dead.

Three others were treated at area hospitals for gunshot wounds.

Robert Williams, who is not related to the victim, was in a car with Tresvour “Trezzie” Robertson, 20, of Rock Island, and Cazmiere D. Graves, 16, of Davenport, when shots were fired from the car at a crowd of people outside the Col, Schaeffer said.

“The defendant fired a gun out the window of the vehicle at subjects he was just involved in a fight with inside the Col Ballroom,” Williams’ arrest affidavit states. “One of the bullets fired struck Michael Williams.”

Graves was the driver, police said. Graves also is considered a witness to the shooting, Williams’ affidavit states.

In a plea deal that dismissed a first-degree murder charge against Graves, the then-15-year-old pleaded guilty in October 2011 to intimidation with a dangerous weapon and as a youthful offender was placed in the Eldora (Iowa) State Training School for Boys.

Robertson was sentenced Sept. 21 to 10 years in prison on an intimidation with a dangerous weapon charge. Charges of first-degree murder and armed with intent were dismissed against Robertson.

“The investigation leads to the conclusion that Robertson did not fire the shot that killed Williams,” Assistant Scott County Attorney Jerry Feuerbach said.

Williams is now the only one of the three still charged with first-degree murder. A trial date hasn’t been set. First-degree murder is punishable in Iowa by life in prison without the possibility of parole.
