The extortion investigation of Mel Gibson's ex-girlfriend Oksana Grigorieva drags on, with the case still not turned over to the L.A. District Attorney.
This has left prosecutors "frustrated" as they look to move forward with the domestic violence case against Mel and the extortion case against Oksana.
Until files are turned over, the D.A. can't file charges or drop the case.
While the investigation was said to be "substantially done" last week, prosecutors now don't think they will receive the case until next week, if that.
"The amount of hours the Sheriff's Department spent investigating Oksana is mind boggling," said one source. As is the fact that Mel ever dated her.
Sheriff's officials have spent months investigating claims that she, or someone close to her, tried to trade her silence in exchange for Gibson's cash.
The two are also in a bitter custody dispute over one-year-old Lucia."The Los Angeles County Sheriff's Department is stalling in turning over the Oksana case to the D.A.," said a source with knowledge of the case.
"It literally started out as probe into claims of extortion and now has evolved into them going over the testimony from the family law case."
"Prosecutors are getting very frustrated that they haven't officially turned it over and it's delaying a decision whether to charge Mel Gibson."
One theory: "It's almost as if the cops are waiting for Oksana to commit a crime to bolster their findings, which so far, are very anemic."
"It's unlikely any charges will be filed against Oksana Grigorieva."
Grigorieva has claimed Gibson punched her in the head at his Malibu home on January 6 if last year, while she held their then-infant daughter.
In Mel's sworn declaration, dated June 23, he admitted to slapping his ex across the face because she was hysterical and he feared for Lucia.
He denies he punched her then or any other time.
It's unclear if Mel will be charged, and what role, if any, Kristian Herzog will play in whether or not authorities decide to pursue either case.
