LOS ANGELES – An attorney for the man who assassinated Robert F. Kennedy said Monday his client was transferred from a prison that houses high-risk offenders to a new facility where his life could be in danger.

Attorney William F. Pepper said Sirhan Sirhan opposed the move from the state prison in Corcoran, which houses high-risk prisoners such as Charles Manson, to Pleasant Valley State Prison in Coalinga.

“Our main concern is for his safety,” said Laurie Dusek, an associate of Pepper. “We are not sure that Pleasant Valley has the ability to protect him. He is a target.”

Pepper said he has new evidence and wants to reopen Sirhan’s case.

Oscar Hidalgo, a spokesman for the Department of Corrections and Rehabilitation, said Sirhan, 65, had requested the transfer and wants to stay in Pleasant Valley.

“After discussing his hesitation with prison officials at Pleasant Valley, Sirhan Sirhan indicated he wanted to stay at the new facility after all,” Hidalgo said. “He can indicate if he feels unsafe at any point and the department will respond appropriately.”
