Fifty years to the day after John F. Kennedy was assassinated, his brother's assassin was moved from a California prison in the Central Valley to a facility in San Diego.

Sirhan Sirhan was convicted for the assassination of U.S. Senator Robert F. Kennedy. On Friday, he was moved from Corcoran State Prison to the Richard J. Donovan Correction Facility in San Diego.

Sources confirmed to Team 10 the move happened, despite the state corrections website still displaying the Corcoran location on Friday afternoon.

The source said case factors was the reason for the location switch, and that it was not uncommon to move an inmate.

The Donovan facility is a level three prison. Level four houses the most dangerous criminals.

Sirhan killed RFK on June 5, 1968, as he campaigned for president in the kitchen of the Ambassador Hotel in Los Angeles. The assassination happened shortly after Kennedy spoke with supporters in the ballroom.

Sirhan, a Palestinian-Jordanian immigrant, shot Kennedy along with several other people. Kennedy died a day later, and the others recovered.

Like his brother's assassination, there have been conspiracy theories about RFK's murder. Sirhan's lawyers once claimed he was framed.

Sirhan is serving a life sentence. He was sentenced to death in 1969, and the sentence was commuted to life in prison in 1972.
