Score One for Mel Gibson—D.A. Says Oksana Extortion Case Is "Under Review"

Sheriff's detectives present evidence to prosecutors who will weigh whether to charge Grigorieva with attempted extortion

Mel Gibson might get some payback, after all.

The Los Angeles County District Attorney has been presented evidence and will now decide whether the Oscar winner's estranged baby mama, Oksana Grigorieva, will face criminal extortion charges involving the release of his infamous rant recordings.

"Sheriff's officials dropped off last part of the Mel investigation today," D.A. spokeswoman Jane Robison tells E! News. "It's under review."

At issue is whether the 40-year-old Russian musician intentionally tried to swindle the erstwhile Lethal Weapon into paying upwards of $15 million in hush money to keep those awfully embarassing voicemails from going public.

Grigorieva had signed a child custody settlement in May 2010 that included Gibson giving her child support, a house and joint custody of their 2-year-old daughter, Lucia—on the condition that she not release the tapes.

But she balked and renegged on the deal. A few months later, recordings of what appeared to be an emotionally unstable Gibson berating and terrorizing her surfaced online. In the wake of their release, Team Mel cried extortion and successfully persuaded authorities to probe the matter.

Grigorieva has repeatedly denied any wrongdoing.

The extortion case is separate from the domestic violence allegations Grigorieva has lodged against Gibson. The D.A. has been reviewing that case since August now, but no charges have been filed.
