TOWN OF HIXON, Wis. -

Authorities have identified a rural Owen teenager who died after a farm accident in west-central Wisconsin.

Clark County sheriff's officials say 16-year-old Jonas Hoover was found Wednesday in a manure tank in the Town of Hixon.

Investigators have said Hoover apparently was spreading manure in a field when he stopped the tractor after emptying the manure tank he was pulling. He entered the empty manure tank, apparently because of a maintenance issue, and was found unconscious inside.

It's not known how long the boy was in the tank. He was taken to a hospital where he was pronounced dead.

Authorities said Friday that the manure tank was malfunctioning and a piece of metal was found near the agitating valve.
