BOULDER CITY, Nev. (AP) -- Authorities have pulled a body from the waters of Lake Mohave near the spot where a 31-year-old Southern California man went missing a week earlier. Officials at Lake Mead National Recreation Area say a visitor spotted a man's body floating near Cottonwood Cove on Sunday afternoon. Rangers who responded recovered it from the water. Coroner's officials haven't yet released the man's identity. Authorities were called Aug. 16 after a man jumped off a boat, began struggling and then slipped under the water. He wasn't wearing a life jacket at the time. Crews who searched the marina afterward were hampered by storms that made the water murky.
