Article reference: 2026000143.

Details of the Arrest

Limited public information is available as of late Friday evening, given the recency of the incident. The charges indicate that authorities allege Cossom’s actions or inactions directly contributed to serious physical harm to a child and/or a dependent individual under his care. Iowa law treats such cases with significant gravity, particularly when serious injury is involved.

•  Child Endangerment – Serious Injury typically applies when a person knowingly exposes a child to a dangerous situation that results in serious bodily injury.

•  Willful Injury Causing Serious Injury involves the intentional infliction of harm resulting in substantial physical impairment or disfigurement.

•  Neglect or Abandonment of a Dependent Person addresses failures to provide necessary care, supervision, or support to vulnerable individuals, which can escalate based on the outcome.

No further details on the victim(s), specific circumstances of the incident, or the ongoing investigation have been released by authorities. Dubuque police have not yet issued a formal press statement on this case.

Legal Implications and Process

Under Iowa Code, these felony charges carry substantial penalties:

•  Felony child endangerment causing serious injury can result in up to 10 years in prison.

•  Willful injury causing serious injury is also punishable by up to 10 years.

•  Neglect of a dependent person penalties vary but can be severe depending on the degree of harm.

Cossom is presumed innocent until proven guilty in a court of law. He will likely appear in court soon for an initial appearance, bond hearing, and formal charging. A no-contact order with any alleged victims is standard in cases of this nature.

Broader Considerations

Child endangerment and neglect cases in Dubuque and across Iowa often involve coordinated responses between law enforcement, the Iowa Department of Health and Human Services (HHS), medical professionals, and child protective services. These incidents underscore the importance of adequate supervision and care for vulnerable dependents.
