Hawaii island police have confirmed the identity of a body that was found in the Wailuku River in Hilo on Sunday as 28-year-old Kelly Mrowinski of Chicago.

Mrowinski and a male co-worker were hiking above Piihonua Falls on Jan. 26, when an apparent flash flood swept then into the Wailuku River on Jan. 26. The male was able to swim to the riverbank, but Mrowinski was missing. Crews conducted an extensive aerial and land search in the following days, but could not locate her. The search continued in late January and early February.

Mrowinski was working as a traveling nurse at Hilo Medical Center.

The Medical Examiner who performed the autopsy concluded the cause of death of “freshwater drowning” and ruled the death as accidental.
