Recent months have seen a series of devastating murder-suicides across the United States, leaving families shattered and authorities searching for motives. While relatively rare, experts suggest this disturbing trend is growing, particularly in cases involving intimate partners.
In one such incident in Hopkins, Minnesota, Nathan Brown was found dead from a self-inflicted gunshot wound. His wife, Kristen, and their seven-year-old daughter, Evie, were found fatally stabbed in their home, where six other children were present and unharmed. Brown's mother was discovered stabbed to death in her home hours later. Police are investigating the incident as a domestic-related homicide, with reports suggesting Kristen Brown was planning to leave her husband. Nathan Brown had no prior convictions beyond a drunk driving incident and had co-owned a licensed daycare with his wife since 2019.
Another case involved Tracey Parker Willetts and Stephen Larnell Willetts, found dead in their North Carolina home the day after their 40th wedding anniversary. Evidence suggests Tracey Willetts fatally shot her husband before taking her own life. A grieving family member revealed the couple had lost both their sons between 2013 and 2014, one to suicide and the other to a terminal illness, which reportedly devastated Tracey's mental well-being.
In Grand Haven, Michigan, Kristopher Karolkiewicz is believed to have fatally shot his wife, Amanda 'Mandy' Karolkiewicz, and their six children, ages five to 15, before turning the gun on himself. Online posts by Amanda Karolkiewicz suggested her husband had an affair and engaged in deceitful behavior, causing her deep insecurity. She also alluded to potential financial troubles and her husband had recently lost his job.
Though police departments do not always track murder-suicides as a distinct phenomenon, a 2025 Columbia University study indicated a growing number of these incidents. Between 2016 and 2022, an estimated 1,052 deaths were associated with murder-suicides annually, with nearly 6,000 deaths linked to the phenomenon over that period. The study found that roughly 3,000 of these were homicides and 2,600 were suicides. "This works out to several deaths per day in the U.S. from homicide-suicide," said Susan Hatters Friedman, a forensic psychiatry professor at Case Western Reserve University. "Rates are higher than earlier estimates, but still homicide-suicide is fortunately relatively rare."
Perpetrators are typically white males, and a significant percentage of homicide victims are killed by a current or former intimate partner. Experts like Dr. Shannon Franklin, a psychologist, note that these incidents rarely stem from a single cause. Potential contributing factors include relationship conflict, significant losses, substance abuse, extreme hopelessness, prior acts of violence, and access to lethal methods. Signs of escalating aggressive behavior or threats can sometimes precede these tragedies.
Financial strain, custody battles, substance abuse, and job loss are also cited as potential contributors. "Acute mental health symptoms, such as severe depression, can also elevate risk of both homicide and suicide," Hatters Friedman added. The Columbia study observed a gradual annual increase in murder-suicides between 2016 and 2022, with firearms being the method in nearly 90% of cases.
While common factors are identified, prevention remains challenging as many individuals experiencing similar issues do not resort to violence. Hatters Friedman's research on psychological autopsies revealed that two-thirds of perpetrators had made verbal or written threats beforehand, often describing themselves as "depressed men who were abusing substances and undergoing separation." Perpetrators can be categorized, with the most common type being intimate-possessive. Other motives can include revenge, illness of a victim, or psychosis.
Authorities emphasize that understanding the precise triggers can be difficult, as these events may be the culmination of long-term planning or an impulsive act. "And a lot of times, there is much more going on under the surface than a family or the news media may know," Hatters Friedman stated. The study identified Alaska and Arizona as states with higher rates of these incidents, while Massachusetts and New Hampshire had the lowest.
