Barquin, 22, was found dead at Coldwater Golf Links in Ames, Iowa, Monday morning.
Police were called to the golf course around 10.20am after golfers found an unattended golf bag. Cops embarked on a search and  discovered a body some distance from the bag.
A criminal complaint says Barquin, the Spanish national from Puente San Miguel, died following a knife attack. Investigators said she died after being repeatedly stabbed at the course, which is near her university campus. Barquin had stab wounds to her upper torso, head and neck.
A man has been charged with her murder. Police arrested 22-year-old Collin Daniel Richards and charged him with first-degree murder.
Police K9 tracked Barquin’s scent to a temporary camp along a creek near the golf course, where Richards had been living in a tent.
The complaint said 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 said he had a deep laceration on his left hand. They also recovered a knife in his possession. Richards’ mugshot was later released, showing what appeared to be defensive scratches under his right eye and on his left cheek.
A second acquaintance told police that Richards arrived at his home on Monday appearing ‘dishevelled and covered in blood, sand and water’. He bathed and left with his clothes in a backpack.
Investigators later recovered two pairs of shorts with blood stains and a knife that Richards allegedly gave to two other people after the slaying, the complaint said.
Those two individuals were driving Richards out of town after the killing, but he asked them to drop him off near the camp so he could get his tent and that’s when officers arrested him. Instead of making good his escape, he has been charged  him with first degree murder in Barquin’s death.
Richards was booked into the Story County Jail  Tuesday morning nd held on a $5million cash bond.
Authorities said Richards has no known address, but he does have a history of domestic violence.

A few months later he was involved in a domestic violence incident. He ended up pleading guilty in September 2015 to first-degree domestic abuse assault.
He spent 90 days in jail, was given one year on probation and a $315 fine.
In January 2017, he pleaded guilty to first-degree harassment and was sentenced to complete an anger management program, according to online records.
At the time, he was also give two years of probation, a 90-day suspended jail sentence and a $625 fine. Later that year, his father called police after coming home to find their residence badly damaged.
Court documents show that Richards admitted to breaking into the house to get his belongings after his parents kicked him out just days before the incident.
He caused more than $200 of damage and was arrested for trespassing.
In June, Richards was arrested for public intoxication. He was allegedly found passed out at a Hy-Vee supermarket.
Barquin, from Puente San Miguel in Spain, was the Iowa State Female Athlete of the Year and was finishing a civil engineering degree this semester, having missed the beginning of her university life to take part in the Youth Olympic Games in China.
Iowa State University said she was one of the most accomplished players in their golf history.
‘Celia had an infectious smile, a bubbly personality and anyone fortunate enough to know her was blessed,’ Iowa State Director of Athletics Jamie Pollard said in a statement from Iowa State.
‘Our Cyclone family mourns the tragic loss of Celia, a spectacular student-athlete and ISU ambassador,’ Pollard added.
Iowa State University President Dr Wendy Wintersteen said: ‘This is a tragic and senseless loss of a talented young woman and an acclaimed student athlete.

Wintersteen described her as a ‘dedicated civil engineering student’ and an ‘acclaimed golfer with a bright future’.
In April, Barquin became only the second women’s golfer at the university to earn medalist honors at a conference tournament when she won the 2018 Big 12 Championship with a three-shot victory (73-71-69=213).
Barquin reached the apex of her career in July, just two months before her death, when she hit a course-record at Penati Golf Resort in Slovakia in the third round on her way to a one-shot victory in the European Ladies Amateur Championship.

She became the third Cyclone women’s golfer to compete in the US Women’s Open Championship and was ranked No. 69 nationally by Golfweek.
Head women’s golf coach Christie Martens said Barquin was ‘loved by all her teammates and friends’ and was an ‘outstanding representative of our school.’
‘We will never forget her competitive drive to be the best and her passion for life,’ Martens added.
Her European win meant she would have been a competitor at next year’s Women’s British Open at Woburn.
Nacho Gervás, technical director of the Spanish Golf Federation, told El País newspaper: ‘She was a player who was heading for the very top, without a doubt.’
Iowa State athletics are planning to honor Barquin when they play Akron at football on Saturday.
Her funeral arrangements are still pending.
