Jennifer Gallagher, 46, her husband of seven years and five-year-old son were in West Lake Okoboji in Iowa when after a night time swim, she was reported missing the morning of August 7.
According to a news release from the local authorities, a family member pulled Jennifer's body from under the dock later that day.
"She worked the morning after the Batman massacre in a very busy unit of the hospital - so she saw everything really, some really bad injuries," her husband, Greg Pinson told Ireland's the Herald.
"She was wonderful to our son Jack. She loved him more than anything in the world. I admired her so much and loved her dearly. We're struggling to cope without her."
Greg explained that he and their son Jack were sleeping when Jennifer decided to take a boat out on the lake.
"She wasn't a very strong swimmer and I suppose she just wasn't able to stay afloat. The hardest thing is I may never know what really happened to Jenny," he said.
Gallagher's death remains under investigation by the Dickinson County Sheriff's Office.
