Fire officials say they suspect arson in two Casa Grande house fires that sparked within minutes of each other.
The Casa Grande Dispatch reports that the two fires were reported about two miles from each other within 15 minutes on Saturday.
Casa Grande Police spokesman Officer Thomas Anderson says no one was injured in either fire as both homes were unoccupied. The exact cause of each fire is under investigation, though arson is suspected.
Investigators are asking anyone with information about either fire to contact the department.
