Authorities call off ground search for brothers

RED LAKE, Minn. (AP) -- Authorities called off a major ground search Sunday on the Red Lake Indian Reservation after they turned up no sign of two young brothers who have been missing since they went out to play Wednesday morning.
But FBI Special Agent Paul McCabe said authorities would continue pursuing leads, and the effort to find 4-year-old Tristan White and 2-year-old Avery Stately was not over.
"We will not stop looking for Tristan and Avery until they are found," McCabe said.
McCabe said it's still unclear whether they wandered off or were taken. "We don't have any indication at this time that foul play is involved," he said.
Investigators had received about 70 phone tips, McCabe said, but none led to the boys so far.
The FBI last week offered a 20,000 reward for information that leads to the boys.
Falling temperatures had dimmed hopes that the boys could have survived in the woods. By Sunday, afternoon temperatures in the area were in the 20s, and there was a chilly wind out of the northwest.
