NAVARRE, Ohio (AP) — A sheriff's office says a natural gas pipeline explosion in Ohio killed a man doing maintenance work.

The explosion Monday killed a Columbia Gas Transmission pipeline worker and caused a large gas leak just south of Canton that forced authorities to evacuate the neighborhood.

The Stark County Sheriff's office identified the victim as 60-year-old Wesley Johnson, of Wooster.

The Repository in Canton reports that investigators believe a cap on the end of a pipeline gave way, but the cause isn't known.

Gas odors drifted more than four miles away after the explosion sent natural gas spewing from a valve.

Most residents were able to return to their homes within an hour.
