Just before 11 p.m. on Thursday, emergency personnel responded to a report that a person may have jumped from a bridge into the Missouri River in Great Falls.
Responding agencies included the Great Falls Police Department and Great Falls Fire Rescue.
They gathered at a spot on the east side of the river between the 9th Street bridge and the old 10th Street bridge.
In addition to visual searching, the GFPD used a drone to scan the entire area around the bridges from bank to bank.
They were unable to launch a search boat because the river in that area is too icy.
As of 11:45 p.m., there was no evidence that anyone had jumped or fallen into the river.
We will update you if there is any new information.
