Investigators from several fire departments and multiple insurance companies now say they can't tell what started a July 12 fire that torched multiple West Lafayette homes.
In a press release sent Friday morning, Wabash Township Fire Chief Ed Ward calls the investigation "exhaustive" and says some causes have been ruled out, such as a natural gas explosion.
The release says it's clear where the fire started -- the home at 3681 Tesla Drive in the Lindberg Village neighborhood on West Lafayette's far west side. But it also says the Indiana Fire Marshal's office now officially lists the fire's cause as "undetermined" and adds foul play is not suspected.
No one was hurt in the blaze, which started around 3 p.m. on a hot Friday afternoon, though one firefighter was treated for heat exhaustion.
In all, five homes were leveled by the flames and another four suffered noticeable exterior damage as a result of the heat.
Chief Ward was not immediately available for comment.
