NEW ORLEANS - Officials say they don't suspect foul play in the death of woman whose body was discovered in an Audubon Park lagoon in New Orleans. 

New Orleans Police Superintendent Michael Harrison said in a statement on Tuesday that they have no evidence so far to suggest foul play in the death.

Police said the woman was spotted floating in the lagoon Monday morning and firefighters retrieved the body. Officials have not released her name or cause of death. Detectives are still waiting on word from the Coroner's Office.

Harrison assured concerned residents that the park is safe, saying they should exercise the same caution they should always use in their everyday lives.

Dr. Jeffrey Rouse said in a brief statement Wednesday investigators believe the middle aged woman was possibly homeless by evidence found at the scene.

Rouse said an autopsy revealed no trauma and that the cause of death was drowning. He says toxicology and other medical testing is pending, as is fingerprint confirmation of the woman's identity.
