South Dakota man dies after donating part of liver

Rod Arnold said. The coroner hasnt determined a cause of death, he said.
"He was a man of uncommon character and someone I looked up to," Rod Arnold said. "What he did for Chad was really just an extension of how he lived his life."
Rod Arnold said his brother "never really wavered" in his decision to give part of his liver to help his brother battle an incurable liver disease known as PSC.
"From the beginning he just said, I gotta do this," Rod Arnold said.
Shortly before the procedure, Ryan Arnold told KDVR-TV he wanted to give his brother the chance to live a long life.
"Im healthy and I know Ill stay healthy," Ryan Arnold told the television station. "Ill recover and I want to see him do the things he wants to do, and spend time with his family, and I want to have him around for a long time."
Rod Arnold said that shortly after the procedure, Ryan went to Chads hospital room and told him, "I love you bro, youre worth it. I believe in you."
Ryan Arnold is survived by his wife, Shannon, and three sons, ages 1, 4, and 6.
Ryan Arnold was an orthodontist in Watertown and was planning to take over his fathers practice there. He loved "pretty much anything outdoors" and spent nearly every moment with his children, going to the lake on a boat and tubing, Rod Arnold said. He enjoyed hunting and fishing and was committed to his church.
"Our desire, if possible, is that what comes out of this is an awareness of the kind of man Ryan was," Rod Arnold said.
