A Plymouth farmer died Monday when his clothing got caught in a shaft connecting an engine and a pump on an irrigation device in one of his fields west of LaPaz. Rick Pertics, 61, of Plymouth told his wife he would be tending to his irrigation equipment overnight, according to Marshall County Deputy Coroner Les Trump. Family members went to the farm Monday when they couldn’t reach Pertics by telephone and found his body next to the irrigation equipment. Trump says the time of death is uncertain but confirms that Pertis died of severe internal injuries. Final autopsy results will be ready in about six weeks.
