SANTO DOMINGO, Dominican Republic — The owners of a nightclub whose roof collapsed and killed more than 230 people in the Dominican Republic capital nearly a year ago appeared in court Monday for their first hearing.

Siblings Antonio and Maribel Espaillat, the owners of Jet Set, are accused of involuntary manslaughter and involuntary assault and battery. If found guilty, they could face up to two years in prison.

The judge showed up but postponed the hearing until April 6.

Lawyers for families crowded the courtroom. As the siblings left, a group of people yelled, “Damn you!” and “Murders, both of you are murderers!”

The collapse on April 8 shook the country, with 236 people killed and more than 100 injured as authorities worked frantically for days to reach people under the rubble.

The Public Prosecutor’s Office has asserted that it has hundreds of pieces of evidence tying the siblings to the collapse.

Spokespeople for the Espaillat brothers did not immediately respond to a request for comment. The siblings were arrested more than two months after the collapse.

Prosecutors have accused the Espaillats of trying to intimidate or manipulate employees. Antonio Espaillat is considered a powerful business person, owning upscale entertainment centers and dozens of local radio stations.

Hundreds were at the nightclub when the roof collapsed, attending a concert by singer Rubby Pérez, who was among the victims. Others included Nelsy Cruz, the governor of Montecristi province and sister of Major League Baseball All-Star Nelson Cruz, and former MLB pitcher Octavio Dotel, who was pulled from the debris but died in a hospital.
