Isaiah went missing at about 7:30 p.m. Tuesday from the 1500 block of 180th Street after playing with his brother, according to his father, Justin Theis.

Since that night, volunteers and law enforcement agencies have searched for Isaiah on foot, with the aid of dogs, and in the air, only stopping the search during overnight hours.

The area that volunteers searched and re-searched Wednesday held corn stalks up to 6 feet tall, ponds and woodlands.  The hundreds of volunteers searched in groups of 10 or 12, taking turns combing through the area and resting so as to keep healthy in the sweltering heat.
