On November 18, 2022, shortly before 5 a.m., 35-year-old Jonah Adams, a Navy veteran from Waldorf, Maryland, broke into the home of his ex-girlfriend JoAnna Cottle on Laurel Oak Road in Chesterfield County, Virginia, and fatally shot her and her three children: 13-year-old Kaelyn M. Parson and 4-year-old twins Kinsey M. Cottle and Jayson L. Cottle. All four victims were pronounced dead at the scene. Adams was the biological father of the twins and had a documented history of domestic violence against the family, including a 2018 domestic assault report and a protective order that had since become inactive. Adams used a sawed-off gun in the killings. He was subsequently convicted of 17 felony charges and sentenced to 13 life sentences plus 18 years in prison.

Individuals Involved
Was an adoptive parent or guardian involved in the death?
Was a biological father involved in the death?
Jonah Adams, the perpetrator, was the biological father of 4-year-old twins Kinsey M. Cottle and Jayson L. Cottle. Document 1 states: "JoAnna Cottle was Adams' ex-girlfriend and he was the father of both Kinsey and Jayson." Document 3 confirms: "Adams…was previously in a relationship with JoAnna Cottle and is the father of Kinsey and Jayson Cottle, according to police."
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)?
For 13-year-old Kaelyn M. Parson, the perpetrator Jonah Adams was not her biological father but was her mother's ex-boyfriend — making him a male paramour. Document 1 states: "JoAnna Cottle was Adams' ex-girlfriend and he was the father of both Kinsey and Jayson," confirming he was not Kaelyn's father. Kaelyn's different surname (Parson vs. Cottle) further supports that she had a different father.
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?
Document 1 reports that Jonah Adams was found guilty and sentenced: "Jonah Adams, a Maryland man found guilty of the 2022 murders…was sentenced to 13 life sentences plus 18 years in prison on Tuesday." He was convicted of 17 felony charges.
Is domestic violence by the parent/caregiver referenced?
Document 1 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 explicitly documents a history of domestic violence by the parent/caregiver (Adams) against the family.
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 references "A domestic assault report and an inactive protective order against Adams from 2018." This 2018 domestic assault report predates the 2022 fatal incident and implies prior criminal involvement (a domestic assault report filed with police strongly suggests a prior arrest, charge, or at minimum a formal law enforcement action). The protective order also implies prior legal proceedings. These are separate from the charges arising from the 2022 murders.
Is substance use by the parent/caregiver referenced?
Notable Details
Several notable details emerge from these documents. First, Adams was identified as a Navy veteran (Document 2: "35-year-old Navy veteran Jonah Adams"). Second, a 2018 domestic assault report and protective order against Adams had become "inactive" by the time of the 2022 murders (Document 1: "an inactive protective order against Adams from 2018"), raising policy questions about the adequacy and duration of protective orders in domestic violence cases. Third, Adams used a sawed-off gun to commit the murders and was charged with armed burglary for breaking into the home (Document 1: "Four counts of using a sawed-off gun to commit a crime" and "One count of armed burglary, entering house to murder"). The lapsed protective order and documented prior domestic violence history that failed to prevent this quadruple homicide point to potential systemic gaps in domestic violence prevention.
