On August 31, 2023, police in Waukee, Iowa responded to a 911 call at a residence on NW Greenwood Place and found 13-month-old DK unresponsive and without a pulse in an upstairs bedroom. The child was pronounced dead at the scene. Officers detected a strong odor of bleach and found several opened bottles of bleach and cleaning substances around the child's body; the carpet and bathroom floor were wet. The child's mother, 26-year-old Yemissi N. Keto, confessed during a police interview that she had held DK on the ground and poured bleach over his face with the intent to kill him. When the bleach failed to make the child pass out, she covered his nose and mouth with her hand, suffocating him to death. A Dallas County jury found Keto guilty of first-degree murder and child endangerment resulting in death, carrying a mandatory sentence of life in prison without the possibility of parole under Iowa law.
Contexts/Conditions
Is there any mention of child drug ingestion or overdose?
Is there any mention of a drowning incident (either intentional or accidental)?
Is there any mention of a firearm incident?
Is there any mention of inappropriate supervision (e.g., child wandered off and drowned)?
Is there any mention of inflicted injury? (e.g. slapped, punched, kicked, choked)
All three documents describe inflicted injuries. Document 1 states Keto "admitted to police that she had poured cleaning products on her 1-year-old son's face before suffocating him." The Law&Crime article provides more detail from the affidavit: "Yemissi (Keto) utilized her hand to cover DK's nose and mouth, causing him to suffocate and stop breathing." The child was deliberately suffocated and had bleach/cleaning products poured on his face.
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?
Is there any mention of outdoor elements (including hot car deaths)?
Is there any mention of prenatal substance exposure (including fetal alcohol syndrome or neonatal abstinence syndrome)?
Is there any mention of sexual abuse?
Is there any specific mention of shaken baby or abusive head trauma?
Is there any mention of prolonged abuse or torture (including restraints, captivity)?
The Law&Crime article, quoting the probable cause affidavit, states: "Keto, the parent of DK, did commit acts of torture and cruelty, which were intended to cause serious injury." The article also describes Keto dousing the child in bleach to try to make him "pass out" before manually suffocating him. The word "torture" is explicitly used in the legal affidavit. However, the evidence describes a single (albeit multi-step and extremely brutal) incident rather than a clear pattern of intentional cruelty over an extended period, which makes this ambiguous with respect to the question's clarifying criteria.
Is there any mention of an unsafe sleeping environment?

Was an adoptive parent or guardian involved in the death?
Was a biological father involved in the death?
Was a biological mother involved in the death?
All three documents identify Yemissi N. Keto as the child's biological mother. Document 1 states she was "a Waukee woman" convicted "for her infant's August 2023 death." Document 2 says she was "charged... in connection to the August death of her 1-year-old son." The Law&Crime article states: "Keto, the parent of DK, did commit acts of torture and cruelty." She was identified as the victim's mother in all sources.
