Brooke Mueller

Charlie Sheen's estranged wife said this week that the TV star vowed to decapitate her and send her severed head to her mother. But Brooke Mueller's statements filed in court are not enough for the Los Angeles Police Department to open a criminal investigation. This week a judge issued a temporary restraining order against Sheen, who has pleaded no contest twice on domestic violence charges. But LAPD officials said they've determined that they can launch a probe only if Mueller files a complaint, which as of Friday she has not. "It is incumbent on her to come forward and make a police report," said Los Angeles Police Sgt. Mitzi Grasso.
