The man who confessed to the twin attacks that killed 93 people in Norway will be arraigned in court Monday and has requested an open hearing for his first appearance so that he can explain his massacre to the public.

But prosecutors have asked that the court be closed to the public and media. They've also asked that Anders Behring Breivik be held for eight weeks, said Oslo District Court spokeswoman Irene Ramm.

Breivik, 32, has confessed he was behind the bombing in downtown Oslo and shooting massacre at a youth camp outside the capital, but denies criminal responsibility. His lawyer Geir Lippestad told Norwegian broadcaster NRK that Breivik has requested to appear in a uniform during the hearing, but didn't know what kind.

Typically, the accused is brought to court every four weeks while prosecutors prepare their case, so a judge can approve his continued detention. In cases of serious crimes or where the defendant has admitted to the charges, longer periods of detention are not unusual.

The search for more victims continues and police have not released the names of the dead. But Norway's royal court said Monday that those killed at the island retreat included Crown Princess Mette-Marit's stepbrother, an off-duty police officer, who was working there as a security guard.

Court spokeswoman Marianne Hagen told The Associated Press that his name was Trond Berntsen, the son of Mette-Marit's stepfather, who died in 2008.

Meanwhile, French police are searching the suspect's father's home Monday. About a dozen officers surrounded the house in Couranel in southern France, entering and leaving at irregular intervals. The house is cordoned off, and reporters do not have access.

The regional gendarme service confirmed the house was that of Anders Behring Breivik's father but would not comment on the search operation. News reports have said Breivik's father, Jens Breivik, has not been in touch with his son in many years.

The attacks rattled Norway, a small and wealthy country unused to political violence, and known internationally as a peace mediator, prominent foreign aid donor and as home of the Nobel Peace Prize. Survivors of the camp shooting on the Utoya island described how a gunman dressed in a police uniform urged people to come closer and then opened fire, sending panicked youth fleeing into the water.

Police say 86 people were killed. About 90 minutes earlier, a car bomb exploded in the government district in central Oslo, killing seven.

More than 90 people were wounded, and others remain missing at both crime scenes.

Norwegian newspaper Aftenposten, without citing sources, reported that Breivik told investigators that he had hoped to reach the island while former Prime Minister Harlem Brundtland was visiting the youth camp of Norway's left-leaning Labor Party, but got there after she had left. Oslo police spokesman Henning Holtaas declined to comment on the report.

Breivik laid out his extreme nationalist philosophy as well as his attack methods in a 1,500-page manifesto. It also describes how he bought armor, guns, tons of fertilizer and other bomb components, stashed caches of weapons and wiping his computer hard drive _ all while evading police suspicion and being nice to his neighbors.

Dr. Colin Poole, head of surgery at Ringriket Hospital in Honefoss northwest of Oslo, told The Associated Press that the gunman used special bullets designed to disintegrate inside the body and cause maximum internal damage. Poole said surgeons treating 16 gunshot victims have recovered no full bullets.

"These bullets more or less exploded inside the body," Poole said. "It's caused us all kinds of extra problems in dealing with the wounds they cause, with very strange trajectories."

Ballistics experts say "dum-dum"-style bullets also are lighter in weight and can be fired with greater accuracy over varying distances.
