Large structure fire in Canton, Mo.

The old Standard Machine building fully engulfed.

Update: The Canton Police Department is investigating Friday night's fire in the downtown area near the Lewis Street Playhouse. Investigators determined the fire was "incendiary in nature" and are now looking for suspects in the arson investigation.

Firefighters were back at the scene of the multiple structure fire Saturday afternoon. Fire rekindled in several places along the old Standard Machine building on Lewis Street, which was destroyed in Friday night's fire.

The Missouri State Fire Marshal andthe Canton Police Department are now investigating the fire that swept through three buildings on the block.

Crews responded to the original fire just after 7:30 p.m. Four other fire departments were called in to assist.

The blaze then spread to the old Janney's paint store after 8:30 p.m.

Crews brought in a bulldozer to start tearing down parts of that store once the fire was contained.

This was the second fire the Canton Fire Department had responded to since 6 p.m. Friday. The first was an abandoned house, at 712 Lewis Street. The fire was determined to be intentionally set. Two juveniles have been placed in the custody of the Lewis County Juvenile Authorities in connection with that fire.

A connection between both fires is currently being investigated.

Mark Bowen has owned the old Standard Machine building for 15 years. There was no active business in that building. Bystanders said the building was more than 100 years old.

The owner of the Lewis Street Playhouse, Jim Crenshaw, said his building had smoke and water damage.

A reporter on scene saw officers take a male teenager into the Canton Police Station just after 9:30 p.m.

No word on what started the fire at this time.
