The disappearance of an antique urn from the Kennedy family compound has added another twist to the investigation of an alleged rape at the mansion.

The urn and other objects allegedly were taken by the 29-year-old woman who claimed to have been raped at the seaside compound March 30, according to published reports Monday.Police spokesman Craig Gunkel confirmed police are looking into the disappearance of the urn. He said he was unaware of anything else being taken from the estate. The urn is being held as evidence, he said.

"I'm not really certain how it (the allegedly stolen items) got involved in this case," Gunkel said. "But the allegations on sexual assault and theft are being investigated as one case."

Police now have blood and hair samples from William Kennedy Smith, a suspect in the alleged rape. It could take up to two weeks for an analysis, Gunkel said. DNA testing will also be performed and will take longer, he said.

Smith, a 30-year-old medical student and nephew of Sen. Edward Kennedy, has denied any wrongdoing.
