Investigators say they’re chasing new leads every day to uncover what led to the killings of 4 men found in an Oklahoma river this week after they were dragged out of the water.
Authorities say the men had been in the water for months, but did not get their clothes wet until they were discovered Monday afternoon in the Red River.
There were no witnesses, it’s all being investigated by the FBI and a specialized unit from the Bureau of Criminal Investigation.
