Charlie Sheen will fight for his freedom beginning Monday when he faces three domestic violence charges stemming from an incident with Brooke Mueller and RadarOnline.com has learned that his defense will attack the credibility of the police officer who interviewed Mueller at the scene. 
 
 RadarOnline.com has also learned that there are no independent witnesses to whatever happened between Brooke and Charlie, complicating the prosecution’s efforts to convict the Two and a Half Men star. 
 
 A source close to the situation told RadarOnline.com that Assistant District Attorney Arnold Mordkin and his team will heavily rely on Mueller’s emotional 911 call where she claimed Sheen had a knife, threatened her and that she was scared for her life.

 The Two And A Half Men star’s legal team, meanwhile, will claim that no offense happened and are gearing up to attack the credibility of local Patrol Officer Valerie McFarlane who has just been fired from the Colorado Police Department. 
 
 McFarlane was one of two responding officers to the couple’s Aspen home after Mueller called 911 on Christmas. 
 
 She was the officer that interviewed Mueller about the incident while the other arresting officer, Rick Magnuson, who interviewed Sheen, also has a murky past. Mueller told McFarlane that Sheen held a knife to her throat and threatened to kill her.

 McFarlane was fired from the police department for a series of incidents, which included allegedly attending and gaining free entry to the Jazz Aspen Snowmass Labor Day Festival in her police uniform while off duty; a direct violation of department policy. 
 
 She also reportedly gained VIP access and snuck her daughter and her daughter’s boyfriend into the VIP area. 
 
 A source told RadarOnline.com: “It’s going to be very interesting because there does not seem to be any plea deal on the horizon and both sides believe they have strong arguments to make.

 “Mordkin does not believe that the defense bringing-up McFarlane’s credibility is as strong as Mueller’s actual 911 call. 
 
 “It should make for an explosive situation and the stakes have never been higher for Charlie Sheen at this stage in his career.” 
 
 Sheen is facing one felony and two misdemeanor charges in connection with the domestic violence incident – since the Christmas arrest he has entered rehab and so has his wife Brooke Mueller.

 RadarOnline.com has also learned there are no witnesses to the incident between Charlie and Brooke, a good situation for the defense. 
 
 As RadarOnline.com reported earlier, Sheen’s legal team will actually try to discredit his wife’s recollection of events to the police because of her alcohol and drug problems. She had been drinking heavily and doing drugs in the hours before calling 911. 
 
 “Charlie is going to contend that everything Brooke told police isn’t true – that she was out of her head, that she was so messed up she didn’t know what was going on,” one source said.

 The other thing Sheen has going for him is Mueller does not want to cooperate with prosecutors. And while she has to be careful about backing off her story because she could be prosecuted for making false statements to police, she also does not have to cooperate with prosecutors. 
 
 Colorado has cracked down on domestic violence cases and won convictions without the testimony of the beaten spouse but this case is more difficult for prosecutors because Mueller’s heavy drug and alcohol usage at the time of the incident will harm her credibility.

I look forward to complying with the court's decision, getting on with my life and putting this behind me."
– The female cop who busted actor Charlie Sheen after he busted up his wife said she's appalled he got off with a quickie visit to a Malibu rehab center. “I wish that the judge could have seen what Mrs. Sheen looked like that Christmas Day and felt the terror that she must have experienced," said Valerie McFarlane. The former cop said she saw red marks on Brooke Mueller's neck and arm and that she was "crying uncontrollably" as she told cops that her husband had threatened her with a knife. A smiling Sheen quipped to TMZ as he left court after sentencing yesterday that he was "off to Disneyland." "This kind of sentence sends the message that victims are not important," said McFarlane. Her attorney, Gloria Allred, called the sentence "laughable." McFarlane was fired shortly after Sheen's arrest for a series of incidents, including getting into a jazz festival free in uniform while she was off duty. Sheen reportedly exploited her firing to help his case.
