SACRAMENTO, Calif. — A judge ruled Thursday that prosecutors can collect DNA, fingerprints and body photographs of the former policeman accused of being California’s Golden State Killer. Attorneys for Joseph DeAngelo, 72, had asked the court to halt the search, arguing the warrant it relied on should no longer be valid because it was granted before his arrest. But Superior Court Judge Michael Sweet sided with the district attorney and said that courts have repeatedly allowed the collection of such evidence because it’s not a form of testimony and would not harm DeAngelo’s right against self-incrimination. “There’s no basis to stop the execution of the search warrant,” he said. DeAngelo, appearing in court in an orange jumpsuit and handcuffed to a wheelchair, said nothing.
