"A tragic accident."

That's what the Maricopa County Sheriff's Office calls the death of a Navy vet who went missing at Lake Pleasant.

Joseph Casey, 34, vanished from the north end of Lake Pleasant on June 21. His body was found the evening of Friday, July 6 in the area of Castle Creek and French Creek roads.

There did not appear to be any trauma to the body nor was there evidence of foul play found at the scene. The state of the decomposition made visual identification impossible.

The body was turned over to the Office of the Medical Examiner for further examination. The Sheriff's Office Crime Lab was able to obtain a fingerprint impression from the body.

On Monday, July 9, the fingerprint was confirmed and verified to belong to Mr. Casey.
