The woman had been given money to do shopping but instead used it for gambling
The incident took place at Obuya market in Kotienoresi village of Rangwe constituency, Homa Bay.
"She had refused to board, fearing she would be beaten after losing the money," one said.
The area chief Kennedy Akoko said the woman left home for the market on Wednesday afternoon but did not return after losing the amount.
The Chief said the husband launched a search and found her at the market, arguing with gambling machine owners.
The man told the business people that he gave his wife the money for shopping but that she took more from their stash.
“The woman was found near a gambling machine," Akoko said. She jumped off the motorcycle and died due to head injuries before they got home."
Homa Bay County Police Commander Marius Tum said Auma fell head first.
"The area is rocky," he said, and urged residents to find amicable ways of solving their problems.
The body was taken to Homa Bay Referral Hospital mortuary.
