Firefighters from three different counties teamed up to fight a large blaze that broke out in Ingleside Monday night.

Video of the fire was provided by Roger Herrera.

It happened in a building that used to be home to the Two Sisters Sewing Shop, located on Main Street. It was being expanded to accommodate a real estate office, and the owner did not notice anything wrong before closing up for the evening.

"We don't know, we don't know if something was left inside," said Elizabeth Vaden-Beebe, the shop owner "We don't know if it was vandalism, because there was no electricity to the building, and it's just waiting for the Fire Marshal to let us know."

State fire marshals arrived at the scene shortly before noon Tuesday. They said it could be a couple of weeks before they determine what caused the building to go up in flames.
