A Sioux Falls man will spend the rest of his life in prison for using a shovel to murder another man at a homeless camp.
A judge on Thursday sentenced Eugene Martin to life in prison without the possibility of parole for killing Robert Thunder Hawk, 45, in May 2012.
Martin said in court that he was sorry for Thunder Hawk's death but he maintains his innocence.
Authorities say Martin and Clint Cottonwood were drinking alcohol with Thunder Hawk when Thunder Hawk made comments about Martin's girlfriend that led to a fight. Cottonwood pleaded guilty to manslaughter last summer and was sentenced to 25 years in prison. He testified against Martin, who was convicted last November of murder.
