Alderman Sam Moore is standing by his testimony: The cops got the wrong man, he says.

Moore, whose ward includes the hardscrabble Ville neighborhood, testified last week at the murder trial of one his constituents, Ramell Dunn, 23, accused of gunning down a gang rival.

The shooting allegedly occurred during the annual Annie Malone parade in May 2005. Dunn was fingered by a witness who, through a bus window, says he spotted him pulling the trigger.

But Moore, who at the time was campaigning for ward committeeman, testified that he never saw Dunn on the street that day.

At City Hall today, Moore reiterated to me that he was less than a half-block from the shooting, and never spied Dunn.

The case has been in the news in more ways than one. A month after the shooting, police officers — searching for Dunn — got into an altercation with his 69-year-old grandmother, blasting her with pepper spray before arresting her for assault.

The officers were later disciplined, and the incident prompted Mayor Francis Slay and Chief Joe Mokwa to deliver their personal apologies to the grandmother, Ruby Harriel.

Members of Dunn’s family were again upset last week when the jury returned its guilty verdict. According to Post-Dispatch court scribe Robert Patrick, Dunn’s mother and sister were arrested after a “near riot” in the courtroom.

Though Moore was not in the courtroom at the time, he shares their frustration.

“They got the wrong person,” Moore says. “They absolutely have the wrong young man.”
