The state fire marshal’s office is investigating two suspicious fires in Herrin – they happened just minutes apart this weekend.

Fire fighters were first called to a home the 1200 block of North 13th Street early Sunday morning. Then just a few minutes later, fire fighters were called to a home on 7 Court C – pretty much on the opposite side of town.

Authorities say both homes were vacant and did not have electricity at the time the fires started.
