NEW CARLISLE, Ind. (AP) _ The leader of a northern Indiana town's volunteer fire department says it is going through a lot of grief and disbelief after its assistant chief was killed at a business blaze this week.

Many people have left flowers and mementos outside the New Carlisle fire station since 41-year-old Jamie Middlebrook died Tuesday night when a roof collapsed on him.

New Carlisle Fire Chief Joshua Schweizer says Middlebrook was the backbone of the department in the town about 10 miles west of South Bend.

Services for Middlebrook will be held at Bethel College in Mishawaka, beginning with visitation on Sunday and his funeral on Monday.

A cause for the fire at K-Fex Inc. hasn't yet been determined.
