Psychologist Flags Possible ‘Contagion Effect’ After Cluster of Valley Murder-Suicides

SCOTTSDALE — A man and a woman died Friday evening in what Scottsdale police believe was a murder-suicide near Pima and McDowell roads, the third similar Valley death investigation in roughly a month — a cluster that has prompted forensic psychologist Dr. John DeLaTorre to warn about a possible “contagion effect.”

Officers responded just after 6 p.m. Friday to reports of a shooting involving two people. Both were found with life-threatening injuries and later died at a hospital, according to Arizona’s Family. Police had not released ages or a detailed public narrative of what led to the shooting as of early Sunday. Neighbors described a quiet cul-de-sac suddenly filled with emergency lights and armed officers.

The Scottsdale case follows a mid-September investigation in Deer Valley in which two older adults were found dead from gunshot wounds inside a home, and a recent Peoria case in which detectives concluded an older couple died in a jointly planned double suicide and left notes. DeLaTorre told Arizona’s Family that when one high-profile tragedy is followed by similar events, some people already in crisis may interpret the news as a cue that “now is the time.”

National aging data underscore why older adults are a focus for prevention advocates: adults 65 and older account for about 22% of U.S. suicides while making up roughly 16% of the population, and adults 75 and older have the highest overall suicide rate of any age group, according to figures cited from the National Council on Aging. DeLaTorre pointed to caregiver fatigue and distorted “altruistic” thinking — the belief that ending both lives somehow spares a partner from suffering — as dynamics that can raise risk when chronic illness or dementia is in the household.

Mental health advocates say open, careful conversation remains a prevention tool even as researchers debate how media coverage interacts with contagion. Anyone in crisis, or anyone worried about someone else, can call or text 988 to reach the Suicide and Crisis Lifeline. Local newsrooms also urge tips and programming feedback through their public contact lines rather than speculation on social media.
