On September 28, 2023, Nancy Johnson (37) drowned her two children — Jacob Johnson (2) and Mia Johnson (5) — in a bathtub at their home in Semmes, Alabama, before hanging herself with a robe belt in a murder-suicide. Mia also had her throat slashed during the drowning, as the 5-year-old apparently fought back. The family was in the midst of a contentious divorce and custody battle; a court had just ordered joint custody with DHR protective supervision days before the killings, with an alternating-weeks arrangement set to begin October 1. The father, Derek Johnson, discovered the bodies after sleeping in an RV on the property and noticing the children were not awake the next morning. Nancy Johnson had a documented history of mental health issues and had pre-planned the act, leaving a suitcase with neighbors the day before and telling them to suspect her husband if she died.

'The DHR worker informed the Defendant (the father) that they do not feel it is safe for the minor children to remain in the care and custody of the Plaintiff (the mother).'" The Fox10 article states that a domestic relations judge "ordered that the Alabama Department of Human Resources be granted 'protective supervision' of them." This demonstrates prior child welfare involvement before the fatal incident.

Parent/Caregiver Factors
Was an adult charged or arrested for the child's death?
Is domestic violence by the parent/caregiver referenced?
Multiple sources reference domestic violence. The Fox10 article states: "Friend said his officers had answered six to eight domestic calls at the house in the last few months." The Fox10 article also mentions a "protection-from-abuse order" granted against the husband. The HuffPost article reports: "Last week, Johnson's husband was arrested on domestic violence charges after he allegedly broke into the home and attacked Johnson in order to take the children." The HuffPost article also states: "Semmes officers have responded to domestic incidents at the home in the past."
Is there any mention that the death occurred in a temporary shelter or while homeless?
Is an intellectual disability of the parent/caregiver referenced?
Is the mental health of the parent/caregiver referenced?
Multiple sources explicitly reference Nancy Johnson's mental health. The People article states: "court records stated that Nancy and Derek Johnson were in the midst of a divorce and custody battle, with Nancy showing signs of mental health issues." Derek wrote that "Nancy was having 'mental issues'" and "was having an identity crisis" since the pandemic. The HuffPost article reports: "Burch told reporters that Johnson had a history of psychiatric issues." The Fox News article states: "He always knew that Nancy struggled with mental health issues." Additionally, a DHR worker expressed concerns about "Johnson's mental health affecting the children's safety" per the HuffPost article.
Is a history of arrests or criminal charges for the parent/caregiver referenced?
The HuffPost article states: "Last week, Johnson's husband was arrested on domestic violence charges after he allegedly broke into the home and attacked Johnson in order to take the children, according to court documents." This arrest occurred approximately one week before the children's deaths on September 28, 2023, and is separate from the fatal incident itself. The husband (Derek Johnson) was a parent/caregiver of the children.
Is substance use by the parent/caregiver referenced?
Notable Details
Several notable details emerge across the sources that are not fully addressed by preceding questions. The HuffPost article reports that the day before the murders, Nancy Johnson "had left the neighbors with a purple suitcase that contained a note alluding to something happening to her, a small amount of cash, some clothing and her phone," and that "she had made comments to her neighbors right before her death that if she died, they should suspect her husband" — suggesting pre-planning and an attempt to frame Derek. Additionally, despite a DHR worker having told Derek "they do not feel it is safe for the minor children to remain in the care and custody of the Plaintiff (the mother)" (HuffPost), and despite six to eight domestic calls to the residence (Fox10), a court ordered joint custody with protective supervision just six days before the murders. The Fox News article reveals Derek had previously obtained emergency custody but dropped it when Nancy "said she wanted to reconcile," which he later described as manipulation. These details collectively suggest significant system-level failures in protecting the children despite multiple warning signs.
