Firefighters responded to a 7:50 a.m. alarm at 267 Katherine St., east of Louisiana Street and south of South Park Avenue.

The fire left an estimated $90,000 damage. The cause remains under investigation.

One firefighter was treated for neck burns, according to unconfirmed reports from witnesses.
