How a Mute tell his freind , a blind, that his wife is being killed by his another best freind, a deaf?

Once there live three people, a blind , a mute and a deaf. They were living together happily in a remote vilaage , far away from the city. They were not educated and are as farmers. Soon later they become best freinds,living in a small hut.One day , the blind married a beautiful woman as his wife. The deaf is very jealous and decided to blind 's wife. Then ,the day came when the deaf came and d blind 's wife but carelessly killed her. When the incident was happening, the mute saw it n decided to tell the blind about it. When blind came home , he thought his wife was dead due to illness as he trusted his freinds would not kill his wife , thus does not want to investigate.The mute wanted to tell him about the incident BUT how can he tell him? [ The Deaf might kill the mute if he know that the deaf knew how blind's wife got murdered.] [NOTE: they live in a remote village thus going to the city might take them up to a few days.] Please Give LOGICAL ANS ....
