On January 12, 2022, 9-month-old Grayson Alvarez and 3-year-old Gianni Gutierrez Riveron were fatally shot by their mother, Givelly Gutierrez-Matos, in their Land O' Lakes, Florida home in a murder-suicide. The parents had recently decided to separate following a dispute over infidelity. The mother and children visited the father at his workplace that morning, where the adults discussed separation plans; the mother displayed no concerning behaviors at that time. When the father returned home that evening, he found the mother and both children unresponsive from gunshot wounds and called 911. The medical examiner determined the cause of death for both children was gunshot wound of the head, ruled as homicides, while the mother's death was ruled a suicide by shotgun wound of the head. The firearm used was legal and registered to the father.

Notable Details
The news article states that "the gun used in the shooting was legal and registered to the husband," which is a notable detail about firearm access in the home. The fatality report also notes that on the morning of the incident, the mother visited the father at his workplace with the children, and "at that time the mother was not displaying any concerning behaviors," highlighting the absence of observable warning signs shortly before the murder-suicide. Additionally, the sheriff described the family as young and stated "deputies had never been called to their home before," and the fatality report confirms "there are no prior investigations involving the children as victims or the mother as an alleged perpetrator." The complete absence of prior risk indicators is significant context for understanding this case.
