MARTINEZ -- A pair of Bay Area cousins have been sentenced to state prison for raping an unconscious woman in Antioch more than a decade ago, a case in which an alleged third attacker is still wanted by police.

Lorenzo Preston, 28, of Vallejo, was sentenced Friday to eight years in prison for the Aug. 5, 2002, attack that occurred when the then-19-year-old victim was passed out from drinking a near-fatal amount of alcohol in an acquaintance's apartment.

Preston's cousin, Brian Bickham, 29, of Oakland, was sentenced in January to six years in prison. The men were each convicted by jury in December of one count of rape of an intoxicated person.

Judge Lewis Davis said Friday that he was giving Preston a stiffer sentence because he had a more extensive criminal history, including a prior prison sentence for pimping and pandering.

Still wanted on a rape charge in the case is Orlando Ellison, a 29-year-old last known to be living in Sacramento.

Warrants for Ellison, Bickham and Preston were issued in 2009 or after, when each of their DNA was matched to the crime through a law enforcement database, according to Contra Costa County deputy district attorney Derek Butts.

The victim, who was unable to attend Friday's sentencing, continues to cope with the severe emotional trauma caused by the rapes, Butts told the judge. She had little support after the event and has had a hard time forgiving herself for putting herself in a position to be victimized.

"These (court) proceedings have helped her tremendously," Butts said.
