Arson is suspected in a house fire that spread to damage two neighboring homes in Alton on Sunday.  The blaze broke out before dawn at an unoccupied home in the 1100 block of East 7th Street, and was fanned by the wind to a next door residence, and also damaged siding to a home on the other side.  No one was injured, and arson investigators will be on the scene today.

The fire was reported just after 4:30am when fire crews were called to the residence.  The fire was reported to be under control after 8am Sunday, but crews were on the scene into the afternoon.  People living inside a duplex next to where the fire broke out were evacuated but may not be able to return to their homes.  A home on the other side of the burned structure sustained mostly exterior damage to siding.
