Dickinson, N.D. (AP) The father of one of three missing college students says they often went star gazing near a lake in southwestern North Dakota and police don't suspect foul play in their disappearances.

Kyrstin Gemar's father, Lenny Gemar, told ABC's "Good Morning America" in a telephone interview on Tuesday that the Dickinson State University softball players would hang out by Patterson Lake.

Police say 22-year-old Kyrstin Gemar, 21-year-old Ashley Neufeld and 20-year-old Afton Williamson called a friend late Sunday night, and she called 911 to report they needed help. Police Lt. Dave Wallace says water was mentioned but the context wasn't clear.

Dickinson police say the search for the women resumed Tuesday morning with at least three airplanes. Members of the fire department also were taking a boat out on Patterson Lake, just southwest of Dickinson, a city of 16,000 people about 100 miles west of Bismarck and 60 miles east of the Montana state line.
