A Clark County, Nevada, coroner's toxicology report released in September found multiple psychiatric and other drugs in the system of a 34-year-old mother who allegedly shot and killed her 11-year-old daughter on February 15, 2026, at a Las Vegas hotel following a cheer competition. The case has drawn attention from Citizens Commission on Human Rights International (CCHR), which is now urging that such toxicology screening be conducted in all evidence homicides, attempted homicides, murder-suicides, and mass acts of violence to determine whether mind-altering psychiatric drugs were present. Currently, such testing is seldom performed, leaving a critical gap in evidence.
CCHR has compiled 145 violent crimes involving individuals taking or withdrawing from psychiatric drugs. Five additional cases this year resulted in 12 deaths, including nine children; two suspects also died. Two suspects were U.S. military veterans, and two were parents who killed their own children. Only the Las Vegas case published toxicology results. Jan Eastgate, President of CCHR International, stated, "There is a blackout on the evidence that could show whether the drugs were present and how they could influence the suspect's behavior." Since 2004, CCHR has identified 57 drug-regulatory warnings and labeling updates linking some psychiatric drugs to violence, aggression, or hostility; 13 cite homicidal ideation.
The other four 2026 cases, based on law-enforcement, family, and court accounts, include a Florida man who stabbed a woman more than 50 times while on psychotropic drugs and may have stopped taking them; a Louisiana veteran who shot eight children, seven his own, before being killed; a California Navy veteran who allegedly beat an Army veteran to death while medicated; and a California man with schizophrenia who stabbed an actor to death after possibly stopping his medication. None of these cases have published toxicology, highlighting the gap CCHR seeks to close.
To address this, CCHR is urging legislators to sponsor bills modeled on Tennessee Public Chapter 897 (SB 2088/HB 2013), effective July 1, 2026. That law requires toxicology screening for psychiatric drugs, including at therapeutic levels, when a deceased person is suspected in a mass attack in which the perpetrator tried to kill four or more people. With consent, it also allows tests on living suspects in specified circumstances. De-identified, HIPAA-compliant results go to a health science center for analysis and recommendations to government. CCHR wants the mandate broader and more public. "The weapon or the body count should not decide whether this evidence is collected," Eastgate said.
CCHR is also concerned about cases where mothers killed or tried to kill their children after documented mental-health struggles, with authorities not reporting toxicology testing or not releasing results. The Las Vegas case is rare in publishing a full psychotropic panel on both mother and child. Other cases include the 2023 Duxbury, Massachusetts, tragedy where a mother strangled her three children after being prescribed about 13 psychiatric drugs, and a 2001 Houston case where a mother drowned her five children after being prescribed antidepressants and an antipsychotic. These cases put potential polypharmacy risks on the public record.
The five 2026 cases update CCHR International's running count from 145 incidents in its report Psychiatric Drugs Create Violence and Suicide to 150. That report compiles violent acts by people reported to be taking psychiatric drugs or withdrawing from them. The Violence Prevention Project's U.S. Mass Shooter Database separately found that 24% of mass shooters in its set had been taking psychiatric drugs, though sealed records and sparse toxicology mean that figure is incomplete. CCHR further documents this issue in its documentary, Prescription for Violence.
CCHR is calling on every state legislature to require psychiatric-drug toxicology—and public, de-identified reporting of results—whenever a suspect in a homicide, attempted homicide, or murder-suicide has a known psychiatric history, a current or recent prescription, or an involuntary hold. Tennessee wrote a starting rule for mass attacks, but the five cases of 2026 and mother cases with no published labs show why that rule does not go far enough. The implications are significant: without routine testing, the role of psychiatric drugs in violent acts remains unknown, potentially affecting public safety, legal outcomes, and mental health policies. For readers, this underscores the need for transparency and accountability in how such cases are investigated and reported.
