A man has been charged with four counts of selling crack cocaine out of a Dubuque candy store near two park playgrounds.

Dwayne Montrell Howard, 35, has pleaded not guilty.

A federal indictment filed in Cedar Rapids says Howard sold crack to an undercover police officer four times in January and February. Three sales were inside Wayne's Candy, a store Howard operated in Dubuque.

A judge Wednesday ordered Howard held without bond, citing a lengthy criminal record in Illinois. Trial is set for Oct. 20.

If convicted Howard faces a maximum prison sentence of 160 years and fine of up to $8 million.

Howard's public defender, Max Wolson, would not comment, a woman in his office said.

The candy store is closed.
