A criminal complaint says a top amateur female golfer from Spain died after being repeatedly stabbed by a homeless man at a course near her university campus in Iowa. A complaint filed Tuesday charges 22-year-old Collin Daniel Richards with first-degree murder in the slaying of 22-year old Celia Barquin Arozamena, who attended Iowa State University. Barquin was found dead Monday morning in a pond at Coldwater Golf Links in Ames. She had stab wounds to her upper torso, head and neck.

The complaint says Richards was living in a tent in a temporary camp near the golf course and that he had allegedly told an acquaintance about his “urge to rape and kill a woman.” Officers say Richards had several scratches on his face and a deep laceration on his left hand. They recovered a knife in his possession.
