In Consalvo v. State, 697 So.2d 805 (Fla. 1996), the Court stated the application of this aggravator as follows: Typically, this aggravator is applied to the murder of law enforcement personnel. However, the above provision has been applied to the murder of a witness to a crime as well. In this instance, "the mere fact of a death is not enough to invoke this factor . . . . Proof of the requisite intent to avoid arrest and detection must be very strong in these cases." In other words, the evidence must prove that the sole or dominant motive for the killing was to eliminate a witness. Mere speculation on the part of the state that witness elimination was the dominant motive behind a murder cannot support the avoid arrest aggravator. Likewise, the mere fact that the victim knew and could identify defendant, without more, is insufficient to prove this aggravator. Additionally, a motive to eliminate a potential witness to an antecedent crime can provide the basis for this aggravating circumstance. And, it is not necessary that an arrest be imminent at the time of the murder. Finally, the avoid arrest aggravator can be supported by circumstantial evidence through inference from the facts shown.
