Whenever I read about horrific violence like the incident in the Fort Lauderdale airport, I wonder what role psychiatric medications played. I wonder if the violent behavior was iatrogenic—was it caused by psychiatric medications? This question will sound counter intuitive for many people. Surely the reverse is true. Psychiatric medication and proper diagnosis should have prevented it. Let’s see if it is.

Esteban Santiago was deployed to Iraq from April 2010 to February 2011 with the 130^th Engineer Battalion, the 1013^th Engineer Company of the Puerto Rico National Guard. After flying from Alaska to Fort Lauderdale Florida, he retrieved his baggage, which incidentally contained a semi-automatic handgun. Santiago had followed proper protocol, checking the weapon with TSA. He went into the men’s bathroom, loaded his weapon and opened fire in Terminal 2 of the airport, killing five people and wounding six others. A witness said he was just randomly shooting people, with no rhyme or reason to it.

Family members reported that he was a changed man when he returned from Iraq. His aunt said his mind was not right. At times he seemed normal, but other times he seemed lost. In Iraq, his unit cleared roads of improvised explosive devices and maintained bridges. Two people in his unit died while he was in Iraq. His aunt said: “He talked about all the destruction and the killing of children. He had visions all the time.” He had changed.

His brother Bryan confirmed that recently Esteban was hallucinating, but said he was receiving psychological treatment. Bryan said he believes the shooting rampage resulted from mental issues that surfaced after the Iraq tour. When Esteban’s tour ended, he was hospitalized for mental problems. Upon his release, he went to Puerto Rico where his father was ill and eventually died. While in Puerto Rico, he received mental health therapy. Esteban eventually moved to Alaska, where he joined the Alaska National Guard in November 2014. He was discharged in August of 2016.

Over the course of 2016, Santiago was repeatedly reported to Anchorage police for physical disturbances. In January of 2016 he was arrested and charged with assault and criminal mischief after an argument with his girlfriend. He allegedly yelled at her while she was in the bathroom and broke down the bathroom door. She told investigators that he tried to strangle her and struck her on the side of the head.

Santiago pleaded no contest to criminal mischief and assault charges. Under a deferred prosecution agreement, his charges would have been dismissed if he complied with the conditions. He was due back in court on March 28^th, 2017 to assess his progress.

While living in Alaska, Esteban continued to receive psychological treatment, according to his brother. Although his girlfriend alerted the family to the situation in Alaska, Bryan said he did not know what mental health problem Esteban was being treated for; they never spoke about it by phone.

His son was born in September of 2016. In November of 2016, Esteban walked into an FBI office in Anchorage to report that his mind was being controlled by a U.S. intelligence agency. He told officials he had a firearm in his car, along with his newborn son. Santiago was checked into a mental health facility; his firearm was logged as evidence for safe keeping. The infant’s mother came for their child. FBI special agent Marlin Ritzman said:

During the interview, Mr. Santiago appeared agitated, incoherent and made disjointed statements. Although he stated he did not wish to harm anyone, as a result of his erratic behavior our agents contacted local authorities, who took custody of Mr. Santiago and transported him to the local medical facility for evaluation.

After conducting database reviews, interagency checks and interviews with his family members, the FBI closed its assessment of Santiago. Agents found no ties to terrorism during their investigation. A CNN senior law enforcement analyst and former FBI assistant director said Santiago hadn’t been adjudicated a felon and he hadn’t been adjudicated as mentally ill. So they couldn’t keep his weapon. The Walther 9-millimeter pistol was returned to him in the beginning of December. Authorities told CNN it was the pistol he used in the shooting incident in Fort Lauderdale.

Typically, Esteban was considered to be a calm young man who was never violent. Recently he began selling his possessions, including his car. Friends and associates noticed more erratic behavior. He bought a one-way ticket to Fort Lauderdale and packed his pistol and two magazines. His carryon bag with the pistol was his only luggage. He flew from Anchorage to Minneapolis to Fort Lauderdale. He retrieved his bag from the baggage claim area and went into a men’s room stall to load his pistol.

He shot the first people he saw, going up and down the carousels of the baggage claim, shooting through luggage to get at people that were hiding. He thinks he fired 15 bullets, aiming at his victim’s heads. A witness said Esteban showed no remorse. He didn’t say anything. “No emotion, no nothing. About as straight-faced as you get.” Afterwards, he just lay face down, spread eagle, waiting for the deputies to come and get him.

The above report was pieced together from information contained in the following reports by The New York Times here,  NJ.com here, CNN here, and NPR here.

There was no explicit mention of Santiago’s repeated involvement in “psychological treatment” involving psychiatric medications, but it highly probable he was taking psychiatric medication of some sort. The lack of any mention of his being prescribed medication may simply be due to confidentiality regulations. Or this silence could be due to the chicken-and-egg argument often applied to incidents involving violence and individuals with known psychiatric problems. Their mental illness, not the drugs to treat it, caused their horrific behavior.

Several psychiatrists have voiced concerns with psychiatry, its over reliance upon medication and denial of serious adverse effects from medication, like violence and suicide. Joanna Moncrieff said she’s sad her profession has not taken the harms drug treatments can do more seriously. She said it has a long history of ignoring the adverse effects of drugs, or attributing them to the underlying disease—of blaming the patient instead of the drug. “Too many psychiatrists have just accepted that drug treatments are good, and have not wanted to contemplate that actually these treatments could be harmful.”

First and foremost, she said, psychiatry needs to adopt a drug-centered model for understanding its drug treatments and what they do to people. Psychiatrists need more information, knowledge and training on what the drugs do—what effects they produce in people; “how they change the way that people think and feel and what sort of impact those changes have on people’s lives.” Watch two brief videos of her expressing her concerns here. You can read more about her “drug-centered model” here on this website: “A Drug is a Drug is a Drug.”

Peter Breggin has raised concerns with the association of violence and antidepressants since the early days of Prozac. In his 1991 book, Toxic Psychiatry, Dr. Breggin related newspaper and scientific reports pointing to an association between Prozac and “compulsive, self-destructive and murderous activities.” He said then he was personally familiar with several cases of compulsive suicidal or violent feelings that developed after taking Prozac. Over the years, his familiarity grew.

In “Psychiatry Has No Answer to Gun Massacres,” Breggin described how the Columbine High School shooter, Eric Harris had a “therapeutic” level of Luvox (fluvoxamine) in his body at the time of the murders.  He had a dose increase in his medication 2 ½ months before the assault and showed signs of drug toxicity five weeks before the event. James Holmes, the Aurora Colorado theater shooter, was in psychiatric treatment with the medical director of student health services, who was considered an expert on campus violence. She was concerned enough about Holmes to report him to the campus police and the campus threat assessment team a few weeks before the assault. When the assessment team suggested putting him on a 72-hour involuntary hold, she rejected the idea. “When Holmes quit school, the school washed its hands of all responsibility for him.”

In a 2010 journal article, “Antidepressant-Induced Suicide, Violence, and Mania: Risks for Military Personnel,” Dr. Breggin related how the adverse effects described in the 2009 edition of the Physicians’ Desk Reference for Zoloft (sertaline) resembled the most frequent psychiatric disorder associated with combat—PTSD—with its hyperalert overstimulated symptoms. He said identical or nearly identical warnings can be found in all antidepressant labels. “All these potentially dangerous symptoms are also commonly seen in PTSD in military personnel, posing the risk of worsening this common military disorder.”

Looking at the revised 2016 medication guide for Zoloft, we see that nothing much has changed with regard to adverse effect warnings. It said Zoloft and other antidepressant medications could increase suicidal thoughts or actions. Symptoms needing immediate attention included: acting aggressively or violent, feeling agitated, restless angry or irritable, an increase in activity or talking more than what is normal, acting on dangerous impulses, trouble sleeping, new or worse anxiety or panic attacks, trouble sleeping, other unusual changes in behavior or mood.

A condition known as “serotonin syndrome” has symptoms such as: agitation, hallucinations, coma and other changes in mental status. Symptoms of potential manic episodes included: greatly increased energy, racing thoughts, unusually grand ideas, severe trouble sleeping’s, reckless behavior, excessive happiness, talking more or faster.

Dr. Breggin concluded his article with the following cautions and recommendations. He said there was a strong possibility the increased suicide rates among active-duty soldiers were in part caused or made worse by the widespread prescription of antidepressant medication. Alone, they can cause a stimulant-like series of adverse effects. “These symptoms of activation can combine adversely with similar PTSD symptoms found so commonly in soldiers during and after combat.” He recommended the military study the relationship between psychiatric drug treatment and suicide as well as random or personal violence. He also suggested that antidepressants should be avoided in the treatment of military personnel.

Another emerging concern of an association between antidepressants and violence is in the research done by Yolande Lucire. She suggested that mutations in CYP450-encoding genes contributed to problems metabolizing psychiatric drugs, and thus were contributing factors in three cases of antidepressant-induced akathisia-induced homicide. The cytochrome P450 family of enzymes is responsible for metabolizing most of the drugs used in psychiatry. You can read her article here. You can also find another article: “Psych Drugs and Violence” on this web site. Within that article you will find a link to another article by Lucire on antidepressant-induced akathisia-related homicide and the CYP450 genes.

Hasn’t there been enough evidence associating suicide and violence with psychiatric medications, especially antidepressants, for open dialogue and more comprehensive scientific research into this public health issue? How many more Columbines, Auroras and Fort Lauderdales need to happen before we begin to address the association of psychiatric drugs and violence?
