On the call, Mueller tells the 911 operator that she is calling to report "domestic abuse," and alleges that Sheen threatened her with a knife, which she says was still in his possession at the time of the call.

She tells the operator, "We have people that are separating us," explaining that her husband was in the back room, and that he was preparing to leave. At one point she says, "He's trying to sneak out through the back right now," but follows that up with, "He's still here."

On the tape Mueller is also heard saying, "I thought I was going to die for one hour," but it wasn't clear whether that statement referred to the alleged incident with Sheen.
