Firefighters in Dubuque County are working to figure out what started a fire at a bowling alley Thursday morning. Fire crews said it happened around 2:40 a.m. at Cascade Lanes at 1303 1st Ave E. Crews did not say why they fire started but they believe it began in the bar area and spread to the bowling lanes. The Cascade fire chief tells TV9 the building appears to be a total loss. "The community will come behind them," said Cascade Fire Chief Denny Green. "And I'm sure - I'm hoping - they will rebuild and be better than ever, but that's going to be up to the owner. They will have a lot of support in this community, there's no doubt about that." No one was inside at the time. TV9 spoke to a firefighter on the scene who also works at the bowling alley. He said everything seemed normal as they closed the lanes down Wednesday night. Fire crews from Bernard and Monticello were called to help out.
