The Des Moines Register reports that 22-year-old Collin Richards entered the plea during a hearing Friday. He faces a mandatory sentence of life in prison when he's sentenced Aug. 23.

Richards had previously pleaded not guilty to the charge and was set to stand trial in September.

Police said Richards fatally stabbed 22-year-old Celia Barquin Arozamena last September while she was playing a round at a public course in Ames, near the university campus, and leaving her body in a pond on the course.

Investigators said Richards had been staying in a small homeless encampment in the woods near the public course.

Barquin Arozamena was a top golfer in Spain as a teenager and came to Iowa State to pursue her career.
