DICKINSON, N.D. (AP) — Police say a dive team found nothing during a search of a North Dakota lake for signs of three missing college softball players .

Dickinson Police Lt. Dave Wallace said Tuesday that a search of a youth fishing area also found no trace of the Dickinson State University students.

The women are identified Kyrstin Gemar, 22, of San Diego; Afton Williamson, 20, of Lake Elsinore, Calif.; and Ashley Neufeld, 21, of Brandon, Manitoba in Canada. The three were believed to be in a white 1997 Jeep Cherokee with California plates when they were last heard from late Sunday night.

Gemar's father has said his daughter and her teammates often went star gazing on Patterson lake, just southwest of Dickinson, about 60 miles east of the Montana state line.
