Jacksonville Sheriff’s Office investigates undetermined death after woman found unresponsive in East Arlington home

What investigators say happened

Jacksonville Sheriff’s Office detectives are investigating an undetermined death after officers were called to an East Arlington home the evening of Friday, January 30, 2026. Police responded at about 8:05 p.m. following a report of an unresponsive person.

When officers arrived, they found an adult woman in a bedroom. Jacksonville Fire and Rescue responded and pronounced her dead at the scene.

Status of the case

Police have classified the incident as an “undetermined death,” a designation typically used in the early stages of an investigation when the cause and manner of death have not yet been confirmed.

Detectives are coordinating with the State Attorney’s Office and the Medical Examiner’s Office as the inquiry continues. Those agencies can play distinct roles: investigators work to establish what occurred and whether any criminal activity is involved, while the medical examiner evaluates medical evidence to determine cause and manner of death.

Who was in the home

Preliminary information indicates the woman was inside the residence with her adult son when she became unresponsive. Police say the son was in the home at the time and is cooperating with detectives. Investigators reported he is being interviewed as part of the fact-finding process.

What information has not been released

As of Saturday morning, police had not released the woman’s identity or age, and no cause of death had been announced. Investigators also had not said whether there were visible signs of trauma, whether a weapon was involved, or whether anyone else may have been present at or near the home.

No arrests were announced, and authorities have not described the case as a homicide.

What typically happens next

• Detectives gather statements and timeline details from people connected to the home and any potential witnesses.

• Investigators may seek physical evidence from the scene and review available surveillance or digital records where applicable.

• The Medical Examiner’s Office may conduct an examination, which can include an autopsy and additional testing before issuing findings.

• If evidence indicates criminal conduct, detectives may consult prosecutors as they evaluate potential charges.

The investigation remains ongoing, and authorities have indicated additional details will depend on investigative and medical findings.
