The Reno Fire Department is investigating a string of fires started along the Fourth Street corridor last night. Three of the fires were starting in trash bins, the first being reported just after 5:30 on the 400 block of Spokane Street. The next was on East Fourth, then a fire on Lake, and another on Ralston Street. Firefighters found no evidence of an accelerant  being used, but they do have a description of a vehicle that may be connected to the fire. They’re looking for a gray Ford F-150 truck seen in the area where the fires started. If you have any information, you can remain anonymous by calling secret witness, 322-4900.
