Officials have determined the identity of a woman whose body was found in the Iowa River last week.

Darling Yosseli Acosta Rivera, 30, of Iowa City was pulled from the Iowa River near the Hills Access campground Feb. 16 at about 1:51 p.m., according to a news release from the Johnson County Sheriff's Office.

Rivera's cause of death has not been determined. Authorities said last week that she was dead when her body was pulled from the river.

In the release, Sheriff Lonny Pulkrabek said officials are requesting the public's assistance with the ongoing investigation into Rivera's death, but understand that some people who knew Rivera may be reluctant to come forward "out of fear of potential immigration enforcement issues."

Pulkrabek stressed in the release that the enforcement of immigration laws is the responsibility of the federal government, not the sheriff's office. Officials will only ask questions relating to the investigation into Rivera's cause of death, he said.

"The sheriff's office is not interested in a person's immigration status, but we are interested in talking to friends, family and acquaintances of Darling Yosseli Acosta Rivera," Pulkrabek said in the release.

Rivera's immigration status is not mentioned in the release.

Anyone with information is encouraged to call the Johnson County Sheriff's Office investigations division at (319) 356-6020 or the sheriff's office anonymous tip line at (319) 354-3729.
