DAVIDSON COUNTY, N.C. -- A string of fires that burned overnight in Davidson County are under investigation.
All four fires happened within three hours overnight and three of them occurred within three miles of each other.
Officials say the close proximity and timing of the fires is "suspicious."
Crews first responded around 1 a.m. to a dumpster fire at 4643 Friedberg Church Road near Mrs. Hanes' Moravian Cookies. A second fire destroyed 10-12 rolls of hay about a quarter of a mile down the road from the dumpster fire.
A third fire was called in around 1:15 a.m. at Arcadia Nursery and Garden Center on N.C. 150 near Community Road.
The fire consumed the main building and an attached greenhouse. The business had been around for 45 years, according to the owner. No injuries were reported.
A neighbor told FOX8's Michael Spears that she believes she heard a car spin out and drive away shortly before seeing the building go up in flames.
A fourth fire, that destroyed a bus, was reported around 3:40 a.m. at Finch YMCA on Mendenhall Street in Thomasville. Officials believe someone intentionally set fire to the bus.
All four fires are under investigation, but authorities haven't officially determined a cause or how they may be linked.
