A woman reportedly died while under Johnson County officers’ control, according to a press release.

A release from the Iowa Department of Public Safety said officials are investigating the death of Crystal Hawkins, 26, following an incident in which she was arrested on a warrant requiring her to serve 30 days in jail.

After Hawkins was brought to the Johnson County Jail on Oct. 10, the release said she became ill prior to being booked and was transported to the University of Iowa Hospitals and Clinics, where she was admitted as a patient.

On Oct. 11, the Johnson County medical examiner informed the sheriff’s office that Hawkins had died while being treated at UIHC.

The release said the DCI and Johnson County medical examiner are working together to determine the cause of Hawkins’ death.

Final results of an autopsy, performed Oct. 12, will not be available for one to two months, the release said.
