A 22-year-old man faces first-degree murder charges in the killing of a former Iowa State University student. Ames Police say Collin Daniel Richards, with no known address, is charged with killing Celia Barquin Arozamena, 22. Cmdr. Geoff Huff says Barquin Arozamena's body was found around 10:30 Monday morning in a pond at Coldwater golf course. Police say it appears she was assaulted, which resulted in her death. In a statement, ISU President Wendy Wintersteen says she's deeply saddened to learn of Barquin Arozamena's death. She says she was a "talented student-athlete and an acclaimed golfer with a bright future." Iowa State athletics plan to honor Barquin Arozamena at Saturday's football game against Akron.
