Law enforcement and other search and rescue workers have been looking since Friday afternoon for a 17-month-old boy who may have fallen into the river at Crow Agency.
The search began after law enforcement got a call that the little boy was missing, Matthew Pryor, special agent in charge of BIA law enforcement, said Saturday afternoon.
Searchers have been looking in and along the banks of the Little Big Horn River, Pryor said.
Searchers saw indicators where someone may have fallen in the water, Pryor said.
Along with BIA officers and agents, searchers have been brought in from Crow Natural Resources, the National Park Service, the FBI and officers from Big Horn and other counties.
There are divers in the water and dogs tracking the boy's scent.
"The dogs brought us to a location where we're really searching hard," Pryor said. "The river's flowing and the water is high, so we're trying to be methodical in our search."
