The trial for one of the owners of a nightclub where a 2003 fire killed 100 people was postponed Wednesday until September.

Michael Derderian, who owned The Station in West Warwick along with his brother, had been scheduled to stand trial July 31. The proceedings were postponed to Sept. 5 to make sure that the new Kent County Courthouse currently under construction will be ready to handle the high-profile case.

A lawyer for Derderian did not immediately return a call Wednesday.

The brothers have each pleaded not guilty to 200 counts of involuntary manslaughter for the Feb. 20, 2003, fire, which began when a rock band's pyrotechnics ignited soundproofing foam.

No trial date has been set for Michael Derderian's brother, Jeffrey.

Daniel Biechele, former tour manager for the band Great White, was sentenced last month to four years in prison after pleading guilty to lighting the pyrotechnics.
