A defense lawyer for former Navajo tribal chairman Peter MacDonald said his client may not survive the jail sentences imposed by a tribal judge.

District Judge Robert Yazzie on Tuesday sentenced MacDonald to 450 days in jail for profiteering in the tribe's $33.4 million purchase of a ranch. The sentence is to be served after a term of nearly six years imposed from a previous trial.MacDonald's attorney, Shannon Robinson, said his client lost 15 pounds while in jail for 20 days before being released to prepare for the second trial.

"My client will not survive this sentence," Robinson said.

He argued that the tribal jail was not built to handle long-term incarcerations.
