Investigating Suicide by Cop incidents: What to remember & what to get

Suicide by cop scenarios can be emotionally trying to the officers involved, which can pose additional issues if officers start to second-guess their actions

Suicide by cop (SBC) incidents pose a number of unique tactical challenges and they can pose considerable investigatory challenges as well. In addition to the usual exploration into how a shooting occurred, more focus than usual needs to be dedicated to explaining specifically why it occurred in SBC encounters.

The aftermath of SBC incidents is often emotionally charged and barbed with claims of excessive force and criminal intent on the part of the officer(s) involved. Rarely will the public and media accept law enforcement claims of being forced into shooting someone. More likely, officers will be challenged with the idea that they should have recognized that the subject was emotionally distraught and offered "help" not gunfire.

Additionally, SBC scenarios can be emotionally trying ‒ sometimes devastating ‒ to the officers involved, which can pose additional issues. They may begin second-guessing their actions and wonder whether they actually could have done something differently to avoid the need to deliver deadly force. Believing that they had no choice but to respond as they did ‒ actually accepting the fact that the suicidal subject did have control of the situation enough to force the officer's hand ‒ can be a tough pill to swallow.

Investigators need to balance the search for shooting-specific evidence with the collection of information that will greatly help with case preparation and evaluation in the likely event of litigation against the police agency, the municipality and the officer.

SBC expert Dr. Barry Perrou, former commander of the hostage/crisis negotiations unit of Los Angeles County Sheriff's Office and the person responsible for creating the agency's Peer Counseling Program, has identified four things to remember when dealing with SBC investigations:

1. Emotions of witnesses may change following an SBC, so timely investigations are essential

Suicidal people often make comments to those close to them that reveal their tendencies. This can be trying on these "confidants," who may spend a great deal of time and energy worrying about them and exhaustively trying to reverse the person's thinking.

When the suicide has been carried out, these people may be fully willing to confirm that the subject was suicidal and to admit that they've been trying to re-route the person's self-destructive path. They may be quick to support an officer's claim that there was nothing that could have been done to prevent the need to deliver deadly force and may even empathize with the officer, given the fact that they, too, have tried to talk the subject out of his suicide mission but were unsuccessful.

As time goes by, however, understanding and empathy may change to confusion, anger and second-guessing of the officer's actions. Witnesses may begin to believe, in hindsight, that less-lethal means could have been used to control the subject and end his threatening behavior. They may forget the true deadly dynamics of the encounter and begin to come to dangerous conclusions relative to the officer's handling of the situation (Claims like, "Maybe he should have just kept talking to him. He wanted to kill himself, not the officer." Or "Come to think of it, how come the officer didn't try to just shoot the gun out of his hand?")

The sooner witnesses and those close to the subject can be interviewed, the better.

2. Don't jeopardize an investigation with second-guessing

Police psychologists have found that one of the most emotionally distressing experiences an officer can have is to be put in a situation over which he or she has no control. Admitting and accepting that he was not able to direct an encounter can be a difficult reality for an officer to come to grips with and in some instances, they just can't do it. They will fall into a trap of believing that there just had to be something else they could have done to prevent being forced into shooting someone. They would rather believe that they failed in some way than accept the fact that the subject had control and was successfully able to force him to pull the trigger. This kind of thinking can be dangerous for the officer emotionally, professionally and legally.

During investigations, it's important to remember your training and the realities of the deadly force encounter you were involved in. Suicidal subjects can become homicidal if their plan to die isn't working out as they had hoped, and any threatening claim or action against you must be taken seriously.

If your life or the lives of others was in danger, you are called upon as a police officer to cease that threat. If that involved delivering deadly force to a subject who refused to comply with your orders and continued to act in a threatening fashion, so be it. You did what you had to do. Believe that. Don't fall prey to voices of doubt that may surface after the fact. Believe in the justifiable nature of your actions and stand firm during post-incident investigations.

3. Remember that you were manipulated…and that can be painful

In SBC scenarios, officers become foils in a subject's plot to die. This experience can be so emotionally intense, says Dr. Perrou, many officers exhibit several of the same symptoms as rape victims. During the investigation, they're required to relive that experience. The resulting emotional aftermath can be extremely painful and if not dealt with appropriately, can have significant and far-reaching consequences.

Realize that painful emotions are common after SBC events and they're normal. Be sure you get some emotional help. If your department provides that kind of support, take advantage of it. If not, seek your own assistance. If another officer in your agency or a neighboring agency has been involved in an SBC, seek him or her out. What did they experience? How did they feel? For the sake of yourself and your career, you must take care of yourself emotionally.

4. Investigatory details that can help prove that the incident was a subject-driven suicide by cop situation are critical

In “Suicide By Cop: Inducing Officers to Shoot,” Dr. Perrou along with former Santa Rosa (Calif.) City Attorney Brien Farrell write, "Recognizing that SBC situations are lethal traps designed to place officers in a no-option situation, it is important to capture all aspects of the subject's psychological 'being' and 'existence' at the time of the shooting, and collect evidence of their psycho-social mind set in the days and possibly weeks leading up to the encounter. SBC situations are emotionally charged investigations. For the public, the media, your agency, the DA’s office, and defense attorneys representing the law enforcement agency and the officers involved, an immediate and comprehensive investigation is critical."

Perrou and Farrell provide the following investigative checklist to better ensure your ability to support a claim of suicide by cop. "Please remember that as mentioned above, time is of the essence," Perrou said. "This information must be gathered immediately. If you wait 12 hours, it will be cold."

He also points out that it's also important to act promptly to preempt any obstructive moves an attorney might make that could hinder your ability to gather what you need quickly.

"Investigators need to balance the search for shooting-specific evidence with the collection of the information [below] that will greatly help with case preparation and evaluation in the likely event of litigation against the police agency, the municipality and the officer," write Perrou and Farrell. "As the solicited information may not appear necessary at the time of the shooting investigation, it is absolutely essential in defining the actions of the subject/suspect, the dynamics of the incident and helps with advising and/or defending the department in the event of a lawsuit."
