Investigators determined that a fire set early Sunday at a Lawrence property rental office was intentionally set.
The fire broke out just after midnight Sunday at Jayhawk Property Management, 1912 W. 25th St.
Fire Chief Mark Bradford stopped short of calling the fire arson, saying Wednesday that more needs to be known about the reason the fire was set before making that ruling.
Bradford would not reveal details about whether the fire was set inside or outside of the building.
He also declined to say what was used to ignite the blaze, which caused an estimated $45,000 in damage to the structure and its contents.
