NAIROBI, Kenya - Kenyan Olympic marathon champion Sammy Wanjiru died in a fall from a balcony after a domestic dispute involving his wife and another woman, police said on Monday.

One police official said Wanjiru committed suicide, while another said he jumped to stop his wife from leaving the house after she discovered him with another woman.

The 24-year-old runner died late on Sunday after jumping from a balcony at his home in the town of Nyahururu, in the Rift Valley, said John Mbijiwe, the police chief in Kenya's Central Province.
