A west-central Missouri pond is the focus of a continuing search for a woman who has been missing for more than three weeks.

Teams are draining the pond in Benton County this week in search for any clues in the disappearance of 72-year-old Hellen Cook. She was last seen July 13, when she walked away from a vacation home near Warsaw. She suffers from Alzheimer's disease.

The woman's shoes and scarf were found in late July near the pond.

A Sedalia man charged with killing a fellow patient at a Columbia veterans' hospital will receive a court-ordered psychiatric exam after an earlier plea of not guilty by reason of mental disease or defect.

The Columbia Missourian reports that Boone County prosecutors and the lawyer for 33-year-old Rudy Perez Jr. agreed on the medical evaluation at a Monday hearing.
