Investigators in Ohio are probing the cause of a blaze that led to the death of a veteran Cincinnati firefighter.

Cincinnati Fire Chief Richard Braun says besides learning the fire's origin, local authorities will make a wide-ranging investigation of the circumstances of 29-year firefighter Daryl Gordon's death and review department policies and procedures. Federal occupational safety authorities also will investigate.

An Ohio State Fire Marshal's office spokeswoman says it is available to help, if needed.

Braun says the department is mourning Gordon's loss amid an outpouring of support from the community and other fire departments. His funeral likely will be next week.

Authorities say the 54-year-old Gordon died at a hospital Thursday morning after falling down an elevator shaft while looking for people to rescue in a burning apartment building.
