Iowa State University student found stabbed to death in pond; homeless suspect arrested

NEVADA, Iowa -- (WHO) -- Twenty-two-year-old Collin Richards went before a judge in Nevada, Iowa on Tuesday, where a $5 million cash-only bond was set. Richards is charged with first-degree murder in the death of 22-year-old Celia Barquin Arozamena, an Iowa State University student and former member of the ISU women's golf team from Puente San Miguel, Spain.

The criminal complaint in the case says Barquin Arozamena's body was found in a pond shortly after 11 a.m. Monday and “the victim sustained several stab wounds to the upper torso, head, and neck.”

While investigators were on scene they encountered a man walking on a nearby trail who said, “What did he do to her?” While speaking with law enforcement the man identified Richards, who he had been staying with in a nearby homeless camp, and told them within the past few days he “had made a statement to the effect of having an urge to rape and kill a woman.”

Around 2 p.m. officers located the camp and while in the area they were approached by Richards. The complaint says officers noticed he had several fresh scratches on his face and a deep laceration on his left hand that he tried to conceal. Richards told officers he stayed with another man during the day. When police interviewed him the man told them Richards “had appeared disheveled and covered in blood, sand, and water.” Officers found bloody clothing that tested positive for human blood in a backpack in Richards' possession. Police also recovered a knife Richards had given to witnesses in the case.
