On February 19, 2023, at approximately 9:30 a.m., 41-year-old Krzysztof Nieroda shot and killed his wife Justyna Nieroda, 41, and their 13-year-old daughter Natalie at their Chatham Place home in Linden, New Jersey, also shooting their 14-year-old son Sebastian in the head. After calling a relative to confess, Krzysztof turned the gun on himself. Police responding to a welfare check found Krzysztof, Justyna, and Natalie dead at the scene with the gun still in Krzysztof's hand, while Sebastian was found alive but critically wounded.

Notable Details
This was a family annihilation in which the father, Krzysztof Nieroda, killed his wife Justyna, their 13-year-old daughter Natalie, and their 14-year-old son Sebastian before committing suicide. The Newsweek article notes that the father "called a family member to confess after he shot his wife" and children, and shortly afterward "died by suicide." The 14-year-old son (this child) was found alive at the scene but later died from his injuries at University Hospital in Newark. Neighbors reported no prior warning signs — Krzysztof was described as "normal," "nice," and "kind," and neighbor Digna Alvarez said "I never heard any fights, nothing." The Newsweek article also contextualizes this within a broader pattern, noting there are "an estimated 11 murder-suicide cases a week across the United States" and that "Nine out of 10 incidents involve a gun."
