Crews put out a fire near a lower beaver trail on Tuesday. A person walking their dog on the Tom and Sophie Vlassis Greenway just off of Martin Luther King Jr. Parkway and Euclid Avenue told us they heard a loud pop around 6:45 a.m. Fire crews doused a tree off the trail that was on fire. Officers on scene said that they found a homeless encampment in the area of the fire. They do not know the cause of the fire. No one was found and no injuries reported.
