UPDATE: Rock Island Fire Marshal Greg Marty said the cause of the explosion at Vintage Rose in Rock Island today was caused by a propane explosion. Equipment that was being used for jewelry repair ignited the explosion, he added.
Three people were treated at the scene for minor injuries. The extent and monetary value of damage is not known at this time. Contractors were on the scene Monday to help shore up two unstable walls. Vintage Rose and the comic book store Tim's Corner, will remain closed for an indefinite amount of time.
ROCK ISLAND -- Emergency crews were at the corner of 14th Avenue and 30th Street after an explosion was reported at antique store Vintage Rose.
