An investigation is still under way to determine what started a fire that caused $20,000 worth of damage to the Utah Valley Meat Packaging Co., 40 S. Second West, Friday afternoon.

Four engines responded to the 1:30 p.m. blaze, which destroyed the basement of the building, said Mark Ostler, acting captain for Fire Station No. 1.The walls of the building, which is being salvaged prior to remodeling, are filled with sawdust and cork insulation and are highly combustible.

A business next door, Modern Cleaners, received minor smoke damage.
