Malachi Lave'atu Osai, 75, of Idaho Falls, passed peacefully at his home on April 5, 2015. He was born April 20, 1939 in Nomuka, Tonga to Osai Lauia and Vailini Kamoto Vakafutu.

He was a member of the first Tongan Ward in the U.S. Malachi was a loving, husband, father, grandfather, and great-grandfather. He enjoyed working, singing, fishing, dancing, joking, and serving. It was his foremost goal to bring his family from Tonga to America for a better life which he accomplished. Malachi said "I am a poor man, my position is to help, not to be successful. Enjoy your life, don't be a burden, remember where you came from. I don't wear a ta'ovala, the low and the dirty is my position. I wear a nice suit and tie to show respect to my father. We came to America."
