On November 18, 2022, at approximately 4 a.m., Jonah Adams — a Navy veteran from Maryland and the ex-boyfriend of JoAnna Cottle — broke into the Cottle family home in the 4200 block of Laurel Oak Road in Chester, Chesterfield County, Virginia. JoAnna Cottle called 911 after seeing Adams outside wearing a camouflage mask, but before police could arrive, Adams forced entry and fatally shot JoAnna (age 39) and her three children: Kaelyn M. Parson (age 13) and 4-year-old twins Kinsey M. Cottle and Jayson L. Cottle, who were Adams' biological children. All four died at the scene from gunshot wounds. Adams used a sawed-off gun. He fled but was arrested later that day at his Maryland home. A prior domestic assault report and a protective order request (which had been denied by a judge) from 2018 helped police identify Adams as the suspect. He was convicted of 17 felony charges and sentenced to 13 life sentences plus 18 years in prison.
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?
All victims were killed by gunshots. Document 1 (WRIC) states Adams "shot four people" and he was convicted of "Four counts of using a sawed-off gun to commit a crime." Document 3 (WTVR) describes officers hearing gunshots while responding and finding the victims dead "all from gunshot wounds."

All three children were shot to death by Jonah Adams. Document 1 (WRIC) states: "he shot four people: JoAnna Cottle, 13-year-old Kaelyn M. Parson and 4-year-old twins Kinsey M. Cottle and Jayson L. Cottle. All four died at the scene." Document 2 (WWBT) states they were "shot to death." Gunshot wounds constitute inflicted injury.

Individuals Involved
Was an adoptive parent or guardian involved in the death?
Was a biological father involved in the death?
Jonah Adams was the biological father of the 4-year-old twins Kinsey and Jayson Cottle. Document 1 (WRIC) states he was "found guilty of the 2022 murders of a Chesterfield County woman and her three children — including his own 4-year-old twins." Document 2 (WWBT) confirms: "Adams was previously in a relationship with JoAnna and is the father of Kinsey and Jayson Cottle." He killed his own biological children.
Was a biological mother involved in the death?
Was a day care worker, babysitter, or nanny 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)?
Jonah Adams was the mother's ex-boyfriend. For Kaelyn M. Parson (who has a different last name and was not Adams' biological child), Adams was a male paramour of the household — the mother's ex-boyfriend. Document 1 (WRIC) states: "JoAnna Cottle was Adams' ex-girlfriend." Document 3 (WTVR) confirms: "her sister and Adams broke up before the babies were born." Adams killed Kaelyn, for whom he functioned as the mother's ex-boyfriend, not a biological parent.
Was another adult relative involved in the death? (e.g., grandfather, aunt)
Was a sibling involved in the death?
Child Characteristics
Was the child adopted?
Was the child homeschooled (including "cyberschooling") or taken out of school?
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 any mention of prematurity or low birthweight?
Is there a history of child protection reports prior to death (for this child or siblings)?
Does the child have a history of foster care (but not in care at time of incident)?
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?
Jonah Adams was arrested, tried, convicted, and sentenced. Document 3 (WTVR) states: "federal agents and police in Maryland arrested 35-year-old Navy veteran Jonah Adams." Document 2 (WWBT) confirms: "A Maryland man was convicted this week for the 2022 murder of a Chesterfield mother and her three children." Document 1 (WRIC) details his sentencing: "sentenced to 13 life sentences plus 18 years in prison."
Is domestic violence by the parent/caregiver referenced?
Multiple documents reference domestic violence by the perpetrator. Document 1 (WRIC) states: "A domestic assault report and an inactive protective order against Adams from 2018 contributed to the Chesterfield County Police Department identifying him as the suspect." Document 3 (WTVR) reports that JoAnna Cottle "previously filed for a protective order, but that it was denied by a judge." These clearly reference a history of domestic violence by Adams against the mother.
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?
Document 1 (WRIC) states: "A domestic assault report and an inactive protective order against Adams from 2018 contributed to the Chesterfield County Police Department identifying him as the suspect." This domestic assault report from 2018 predates the 2022 murders by four years and indicates prior criminal involvement (a documented domestic assault allegation with law enforcement). While not explicitly described as an arrest or conviction, it represents a documented criminal incident prior to the fatal event.
Is substance use by the parent/caregiver referenced?
Notable Details
Several notable details emerge from the documents that may materially affect understanding of this case. Document 3 (WTVR) reports that JoAnna Cottle had "previously filed for a protective order, but that it was denied by a judge," while Document 1 (WRIC) references "an inactive protective order against Adams from 2018." The denial of a protective order four years before the murders represents a potential systemic failure in domestic violence protection. Additionally, Document 3 (WTVR) describes how the mother called 911 about a possible intruder after seeing Adams outside wearing "a type of camouflage mask," and officers "were able to hear gunshots" while responding but arrived to find the suspect gone and all four victims dead. Adams was also identified as a Navy veteran, and the weapon used was a sawed-off gun (an illegal weapon). Adams received 13 life sentences plus 18 years and was ordered to pay over $1.3 million in fines and court costs.
