On July 3, 2023, in St. Ann, Missouri, 14-year-old Kyrien D. Stevenson was fatally shot by Coleman McIlvain, his mother's 34-year-old boyfriend. The shooting occurred after an argument in which Kyrien's mother, 30-year-old Seychelle Schaumburg, refused to let McIlvain drive while intoxicated. McIlvain shot Seychelle in the face, killing her, then turned the gun on her three children: Kyrien was found dead in the kitchen, his 5-year-old sister Ushara Schaumburg was shot three times and died at a hospital, and his 9-year-old sister Akuri Schaumburg survived after being shot in the hand. McIlvain then shot himself and also died at a hospital, making this a murder-suicide. A domestic violence claim had been filed against McIlvain just one week before the fatal shooting.

Is there any mention of a drowning incident (either intentional or accidental)?
Is there any mention of a firearm incident?
The medical examiner report states the cause of death as "Gunshot wound of chest." The Fox2Now article states that "an argument over driving intoxicated led Coleman Mcilvain to shoot and kill his girlfriend and two children," and the Kansas City Star article describes McIlvain pulling "out a firearm and shoot her right in the face." This is explicitly a firearm incident.

The medical examiner report (MO_23_1742.pdf) lists the cause of death as "Gunshot wound of chest" and the manner of death as "Homicide." The Kansas City Star article further states that the 14-year-old son "was pronounced dead in the kitchen with a gunshot wound to the head." This was an intentionally inflicted gunshot injury by Coleman McIlvain, the mother's boyfriend.
Is there any mention of malnutrition, starvation, or dehydration?
Is there any mention of medical neglect?
Is there any mention of a motor vehicle crash or incident?
Is there any mention of a murder-suicide incident?
The Kansas City Star article explicitly states: "Police said McIlvain shot himself after shooting his girlfriend and her three children, KTVI. He also died at a hospital." McIlvain killed Seychelle Schaumburg and two of her children, attempted to kill the third child, and then fatally shot himself, constituting a murder-suicide.

Individuals Involved
Was an adoptive parent or guardian involved in the death?

Was a female paramour or friend involved in the death (e.g., girlfriend, stepmother)?
Was a foster parent involved in the death?
Was a male paramour or friend involved in the death (e.g., boyfriend, stepfather)?
Both news articles identify the perpetrator as Coleman McIlvain, the mother's boyfriend. The Fox2Now article states: "an argument over driving intoxicated led Coleman Mcilvain to shoot and kill his girlfriend and two children." The Kansas City Star describes him as the woman's boyfriend: "A woman was shot in the face by her boyfriend, who then turned the gun on her three children."
Was another adult relative involved in the death? (e.g., grandfather, aunt)
Was a sibling involved in the death?
Child Characteristics

Was the child in foster care at the time of the incident?
Was the child living with relatives at the time of the incident (but not parents)?
Is there any mention of a neurological developmental child disability? (e.g., autism, intellectual disability, nonverbal)
Is there any mention of a physical child disability? (e.g., feeding tube)

Is there a history of a sibling death (separate incident from this death)?
Parent/Caregiver Factors
Was an adult charged or arrested for the child's death?
Is domestic violence by the parent/caregiver referenced?
The Fox2Now article states: "A week before the incident, Akuri's family filed a domestic violence claim against Mcilvain, after a fight escalated between the couple." Seychelle's grandmother Laura Ludwig described: "He just started screaming at her … listening to the voice, I could hear it escalate …. The anger kept escalating." The fatal shooting itself was also preceded by an argument between McIlvain and his girlfriend.
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?
Is a history of arrests or criminal charges for the parent/caregiver referenced?
A neighbor quoted in the Fox2Now article states: "the fact that this man had a rap sheet as long as the street, more could have been done to protect these kids." This strongly implies McIlvain had a significant prior criminal history predating the fatal incident. While the specific charges are not listed, the statement clearly refers to a record that existed before this shooting.
Is substance use by the parent/caregiver referenced?
Both news articles describe McIlvain (the mother's boyfriend who was acting in a caregiver role in the household) as being intoxicated at the time of the incident. The Fox2Now article states the argument was "over driving intoxicated" and quotes the police chief saying "because he's intoxicated and drunk." The Kansas City Star reports "The 9-year-old told police the shooting happened after the girl's mother would not let McIlvain drive drunk."
Notable Details
Several substantive details emerge from the text. First, a domestic violence claim was filed against Coleman McIlvain just one week before the fatal shooting, as the Fox2Now article reports: "A week before the incident, Akuri's family filed a domestic violence claim against Mcilvain, after a fight escalated between the couple." Despite this report and McIlvain's extensive prior criminal record (a neighbor stated "this man had a rap sheet as long as the street"), no intervention prevented the fatal shooting. Neighbors explicitly called out a systemic failure, with one stating "more could have been done to protect these kids." Additionally, the 9-year-old survivor Akuri told a neighbor immediately after the shooting: "I wanted to tell you, but I didn't know how," suggesting the children may have been aware of escalating danger. The incident was a mass shooting that killed three family members and the perpetrator, with only the 9-year-old surviving despite being shot at seven times. There is also a discrepancy between the medical examiner report (listing cause of death as "Gunshot wound of chest") and the Kansas City Star article (reporting the 14-year-old was found "with a gunshot wound to the head").
