Investigators are trying to figure out what caused a fire at a Yakima bar that lead to $300,000 worth of damage. Firefighters responded to the Lewisville Tavern at 301 North Sixth Avenue at around 3:15 this morning. According to a press release, the fire that started on the outside of the building and then spread to the attic is deemed suspicious. Crews were hampered by the buildings layout so a hole was cut in the roof. The release says a firefighter had part of the ceiling fall on him and received minor injuries. About two dozen firefighters tried putting it out including some from the Yakima Training Center.
