Whether Mel Gibson and Oksana Grigorieva will face any criminal charges following their nasty breakup now lies in the hands of Los Angeles prosecutors.
L.A. Sheriff officials confirmed Wednesday that they’ve wrapped a seven-month-long investigation into allegations that the Russian musician tried to extort millions from the actor/director with recorded phone conversations.
Gibson, meanwhile, is accused of domestic violence after a scuffle between the former couple at his Malibu home in Jan. 2010. Gibson admitted in court documents only to slapping Grigorieva to restrain her from shaking their baby Lucia.
If charged and convicted with extortion, Grigorieva could face up to several years in prison, however experts say the case would be difficult to prove since it’s common to use incriminating evidence as a bargaining chip in civil law cases.
Gibson, if charged and convicted with domestic violence, would likely not face any significant jail time since he has no prior record of the alleged crime and it’s debatable whether Grigorieva’s alleged injuries rise to a felony level.
